The signals used by a scanning electron microscope to produce an image result from interactions of the electron beam with atoms at various depths within the sample. Various types of signals are produced including secondary electrons (SE), reflected or back-scattered electrons (BSE), characteristic X-rays and light (cathodoluminescence) (CL), absorbed current (specimen current) and transmitted electrons. Secondary electron detectors are standard equipment in all SEMs, but it is rare for a single machine to have detectors for all other possible signals.
That doesn't mean you won't make any money at the outset. No, as long as you configure the right free offer to capture those all-important email addresses on your squeeze pages, and you build a great value chain with excellent sales funnels, you'll succeed. If all that sounds confusing to you, don't worry, you'll learn over time. That's what internet marketing is all about. It's a constant and never-ending education into an oftentimes-convoluted field filled with less-than-scrupulous individuals.
In a typical SEM, an electron beam is thermionically emitted from an electron gun fitted with a tungsten filament cathode. Tungsten is normally used in thermionic electron guns because it has the highest melting point and lowest vapor pressure of all metals, thereby allowing it to be electrically heated for electron emission, and because of its low cost. Other types of electron emitters include lanthanum hexaboride (LaB

Sometimes considered to be a part of SEM, social media sites like Twitter, YouTube, Facebook, and Delicious have search fields and also pass authority to sites through links. Making sure your content and links are placed (where necessary) on these social media sites can increase your influence in user search engine queries. SMM is a rapidly growing area of Internet marketing but to discuss it further is beyond the scope of this Guide.
For any "attract" video, avoid speaking too much about your product. Instead, let your brand values and personality be your north star(s). Finally, because these videos can live on a variety of channels, keep in mind the strategies of each platform. For example, a Facebook video might have a square aspect ratio and text animations for soundless viewers.  http://www.youtube.com/watch?feature=youtube.be&v=7bNPg8UbhaE

Pay per click (PPC) advertising, commonly referred to as Search Engine Marketing, delivers targeted traffic and conversions and will yield results faster than organic search engine optimization. Successful PPC marketing programs offer incredible revenue and brand-building opportunities. However, without a thorough understanding of how PPC works, it is very easy to mismanage valuable advertising budgets. That’s where we come in!
Non-profit corporations and political entities use Internet marketing to raise awareness about the issues they address and engage individuals in their campaigns. They strongly favor social networking platforms because they are more personal than websites and they are easy to share, increasing the “viral” word-of-mouth effect that is so prevalent in online media.
There's a lot to learn when it comes to the internet marketing field in general, and the digital ether of the web is a crowded space filled with one know-it-all after another that wants to sell you the dream. However, what many people fail to do at the start, and something that Sharpe learned along the way, is to actually understand what's going on out there in the digital world and how businesses and e-commerce works in general, before diving in headfirst.

Measurement of the energy of photons emitted from the specimen is a common method to get analytical capabilities. Examples are the energy-dispersive X-ray spectroscopy (EDS) detectors used in elemental analysis and cathodoluminescence microscope (CL) systems that analyse the intensity and spectrum of electron-induced luminescence in (for example) geological specimens. In SEM systems using these detectors it is common to color code these extra signals and superimpose them in a single color image, so that differences in the distribution of the various components of the specimen can be seen clearly and compared. Optionally, the standard secondary electron image can be merged with the one or more compositional channels, so that the specimen's structure and composition can be compared. Such images can be made while maintaining the full integrity of the original signal data, which is not modified in any way.

SEO is the discipline that allows people and websites to access the potential of the internet. It’s about knowing when your site is the right result, and admitting to yourself when it is the wrong result. SEO is making your company and services more accessible to your prospective customers by studying what they need and creating the resources to serve them.
As we’ve been told by the Google rater’s guide, we ideally want to focus upon building sites that raters might see as involving Expertise, Authoritativeness, and Trustworthiness. A recent Google patent told us that it might look at search results to gauge the authoritativeness of pages in search results, and if pages within those results don’t meet a specific threshold of authoritativeness, Google may perform a search on a related query to find other authoritative search results, which could then be blended into search results for that initial query.
There are numerous repositories to source affiliate products and services from. However, some of the biggest are sites like Clickbank, Commission Junction, LinkShare and JVZoo. You'll need to go through an application process, for the most part, to get approved to sell certain products, services or digital information products. Once approved, be prepared to hustle.
As the number of sites on the Web increased in the mid-to-late 1990s, search engines started appearing to help people find information quickly. Search engines developed business models to finance their services, such as pay per click programs offered by Open Text[7] in 1996 and then Goto.com[8] in 1998. Goto.com later changed its name[9] to Overture in 2001, was purchased by Yahoo! in 2003, and now offers paid search opportunities for advertisers through Yahoo! Search Marketing. Google also began to offer advertisements on search results pages in 2000 through the Google AdWords program. By 2007, pay-per-click programs proved to be primary moneymakers[10] for search engines. In a market dominated by Google, in 2009 Yahoo! and Microsoft announced the intention to forge an alliance. The Yahoo! & Microsoft Search Alliance eventually received approval from regulators in the US and Europe in February 2010.[11]

Marketing departments are the primary beneficiaries of SEM. By paying for certain keyword terms, they can drive inbound traffic to websites. SEM helps boost traffic by making products and services display more prominently given paid advertising. While website browsers may benefit from SEM by having products and services more easily brought to their attention, they also have to be on guard against website activity that is spurious or doesn’t address their needs.
Both use keyword research to uncover popular search terms. The first step for both SEM and SEO is performing keyword research to identify the best keywords to target. The research includes looking at keyword popularity to determine the top keywords or buying keywords that your ideal audience searches for. It also includes looking at keyword competition to see what other brands are targeting the same keywords and determining what you will need to do to compete with those other companies. http://m.youtube.com/watch?feature=player_embedded&v=7bNPg8UbhaE

Social Media Marketing - The term 'Digital Marketing' has a number of marketing facets as it supports different channels used in and among these, comes the Social Media. When we use social media channels ( Facebook, Twitter, Pinterest, Instagram, Google+, etc.) to market a product or service, the strategy is called Social Media Marketing. It is a procedure wherein strategies are made and executed to draw in traffic for a website or to gain attention of buyers over the web using different social media platforms.
The criteria and metrics can be classified according to its type and time span. Regarding the type, we can either evaluate these campaigns "Quantitatively" or "Qualitatively". Quantitative metrics may include "Sales Volume" and "Revenue Increase/Decrease". While qualitative metrics may include the enhanced "Brand awareness, image and health" as well as the "relationship with the customers". http://youtube.com/v/e29F5n3ea0I

Google's search engine marketing is one of the western world's marketing leaders, while its search engine marketing is its biggest source of profit.[17] Google's search engine providers are clearly ahead of the Yahoo and Bing network. The display of unknown search results is free, while advertisers are willing to pay for each click of the ad in the sponsored search results.
DisabledGO, an information provider for people with disabilities in the UK and Ireland, hired Agency51 to implement an SEO migration strategy to move DisabledGO from an old platform to a new one. By applying 301 redirects to old URLS, transferring metadata, setting up Google webmaster tools, and creating a new sitemap, Agency 51 was able to successfully transfer DisabledGO to a new platform while keeping their previous SEO power alive. Additionally, they were able to boost visitor numbers by 21% year over year, and the site restructuring allowed DisabledGO to rank higher than competitors. Their case study is available on SingleGrain.com.
In the 2000s, with more and more Internet users and the birth of iPhone, customers started searching products and making decisions about their needs online first, instead of consulting a salesperson, which created a new problem for the marketing department of a company. In addition, a survey in 2000 in the United Kingdom found that most retailers had not registered their own domain address.[12] These problems made marketers find the digital ways for market development.

Companies often use email marketing to re-engage past customers, but a “Where’d You Go? Want To Buy This?” message can come across as aggressive, and you want to be careful with your wording to cultivate a long-term email subscriber. This is why JetBlue’s one year re-engagement email works so well -- it uses humor to convey a sense of friendliness and fun, while simultaneously reminding an old email subscriber they might want to check out some of JetBlue’s new flight deals.
Finally, it’s critical you spend time and resources on your business’s website design. When these aforementioned customers find your website, they’ll likely feel deterred from trusting your brand and purchasing your product if they find your site confusing or unhelpful. For this reason, it’s important you take the time to create a user-friendly (and mobile-friendly) website.
Google’s Accelerated Mobile Project (AMP) will gain even more popularity. AMP is a collaboration between developers and other industry professionals to create a massive open source library that offers users more opportunity to create quick and smooth mobile-friendly web pages. This is one area where we’ll be seeing the death of slow-loading pages that rank low. The use of AMP has resulted in huge increases in mobile searches and traffic from major publications such as the Washington Post and Slate.
Search engine optimization consultants expanded their offerings to help businesses learn about and use the advertising opportunities offered by search engines, and new agencies focusing primarily upon marketing and advertising through search engines emerged. The term "search engine marketing" was popularized by Danny Sullivan in 2001[12] to cover the spectrum of activities involved in performing SEO, managing paid listings at the search engines, submitting sites to directories, and developing online marketing strategies for businesses, organizations, and individuals.
Around the world, 91 percent of consumers are likely to reward brands for authenticity and share the brand with friends and family, and 62 percent are likely to purchase from or show greater interest in purchasing from a brand that authentically expresses itself. Interestingly, U.S. consumers were less likely to build trust with new brands as compared to others globally, particularly the openness expressed by Asian consumers. For U.S.-based businesses marketing domestically, video content is the key to building trust.
Brand awareness has been proven to work with more effectiveness in countries that are high in uncertainty avoidance, also these countries that have uncertainty avoidance; social media marketing works effectively. Yet brands must be careful not to be excessive on the use of this type of marketing, as well as solely relying on it as it may have implications that could negatively harness their image. Brands that represent themselves in an anthropomorphizing manner are more likely to succeed in situations where a brand is marketing to this demographic. "Since social media use can enhance the knowledge of the brand and thus decrease the uncertainty, it is possible that people with high uncertainty avoidance, such as the French, will particularly appreciate the high social media interaction with an anthropomorphized brand." Moreover, digital platform provides an ease to the brand and its customers to interact directly and exchange their motives virtually.[33]

In secondary electron imaging (SEI), the secondary electrons are emitted from very close to the specimen surface. Consequently, SEI can produce very high-resolution images of a sample surface, revealing details less than 1 nm in size. Back-scattered electrons (BSE) are beam electrons that are reflected from the sample by elastic scattering. They emerge from deeper locations within the specimen and, consequently, the resolution of BSE images is less than SE images. However, BSE are often used in analytical SEM, along with the spectra made from the characteristic X-rays, because the intensity of the BSE signal is strongly related to the atomic number (Z) of the specimen. BSE images can provide information about the distribution, but not the identity, of different elements in the sample. In samples predominantly composed of light elements, such as biological specimens, BSE imaging can image colloidal gold immuno-labels of 5 or 10 nm diameter, which would otherwise be difficult or impossible to detect in secondary electron images.[13] Characteristic X-rays are emitted when the electron beam removes an inner shell electron from the sample, causing a higher-energy electron to fill the shell and release energy. The energy or wavelength of these characteristic X-rays can be measured by Energy-dispersive X-ray spectroscopy or Wavelength-dispersive X-ray spectroscopy and used to identify and measure the abundance of elements in the sample and map their distribution.


Using Dr Dave Chaffey's approach, the digital marketing planning (DMP) has three main stages: Opportunity, Strategy and Action. He suggests that any business looking to implement a successful digital marketing strategy must structure their plan by looking at opportunity, strategy and action. This generic strategic approach often has phases of situation review, goal setting, strategy formulation, resource allocation and monitoring.[59]
It is very rare for an individual to enter a management role early in his or her career. Most marketing managers have spent several years working somewhere else on a marketing team. This assumes the existence of at least a bachelor's degree, but an advanced degree such as a master’s in marketing or business administration can give an aspiring manager a deciding edge.

SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[48] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[49]
Using influencers to market your products or services is a great way to quickly saturate yourself into the marketplace, no matter what you're peddling. However, finding the right influencer at the right price is the hard part. You don't necessarily have to go to the top-tier influencers; you can also opt for micro-influencers (those that have 10,000 to 100,000 followers or fans).
Display advertising - As the term infers, Online Display Advertisement deals with showcasing promotional messages or ideas to the consumer on the internet. This includes a wide range of advertisements like advertising blogs, networks, interstitial ads, contextual data, ads on the search engines, classified or dynamic advertisement etc. The method can target specific audience tuning in from different types of locals to view a particular advertisement, the variations can be found as the most productive element of this method. http://m.youtube.com/e/e29F5n3ea0I
The first component of Google's trust has to do with age. Age is more than a number. But it's not just the age when you first registered your website. The indexed age has to do with two factors: i) the date that Google originally found your website, and; ii) what happened between the time that Google found your website and the present moment in time.

Try sparking your audience’s curiosity by asking questions and using teasers to hook their attention right away. Your video should immediately convey its value and answer that “why should I watch it?” question that will be on your audience’s mind. Should they watch it because it will make them laugh, because it will inspire them to act or because it will teach them something new? http://www.youtube.com/v/e29F5n3ea0I

You should optimize your site to serve your users' needs. One of those users is a search engine, which helps other users discover your content. Search Engine Optimization is about helping search engines understand and present content. Your site may be smaller or larger than our example site and offer vastly different content, but the optimization topics we discuss below should apply to sites of all sizes and types. We hope our guide gives you some fresh ideas on how to improve your website, and we'd love to hear your questions, feedback, and success stories in the Google Webmaster Help Forum1.
Why It Worked So Well: Not sure. The opening frame image (idiot holding a plastic head) may have had something to do with it as it looked unusual? Or, it may have been the topic, which was asking a question that was clearly going to be answered in the video? Or was it that the topic was challenging the expected norm from a company that does SEO work? I am not sure!

Completion rate: Completion rate is the number of people who completed your video divided by the number of people who played it. Completion rate, and other engagement metrics, are a great way to gauge a viewer’s reaction to your video. Do you have a low completion rate? Are people all dropping off at a certain point? This might be a sign that your video content is not resonating with your target audience. https://www.youtube.com/e/e29F5n3ea0I


2. Domain authority and page authority. Next, you should learn about domain authority and page authority, and how they predict your site’s search rankings. Here’s the basic idea; your site’s domain authority is a proprietary score, provided by Moz, of how “trustworthy” your domain is. It’s calculated based on the quantity and quality of inbound links to your website. The higher it is, the higher all your pages across your domain are likely to rank in organic search results. Page authority is very similar, but page-specific, and you can use it to engineer a link architecture that strategically favors some of your pages over others. Authority depends on the authority and volume of inbound links.

On the other hand, a website can have a fantastic paid search strategy in place and experience short-term gains in traffic and click-through rates (CTR) while missing SEO optimization completely. In this case, growth will be fast and visitors/clicks will be generated through a more diverse set of keywords—but it may cost quite a bit of money that would be more effective elsewhere.

Consider the age of your business. If you just opened your business and launched your website, it’s going to take time to develop your SEO and begin to appear organically in the search. While that doesn’t mean you shouldn’t put together an SEO strategy, it does mean that you could benefit from an SEM strategy until you build your SEO. SEM is an effective way to drive traffic while building organic SEO.
Nonconducting specimens may be imaged without coating using an environmental SEM (ESEM) or low-voltage mode of SEM operation.[17] In ESEM instruments the specimen is placed in a relatively high-pressure chamber and the electron optical column is differentially pumped to keep vacuum adequately low at the electron gun. The high-pressure region around the sample in the ESEM neutralizes charge and provides an amplification of the secondary electron signal.[citation needed] Low-voltage SEM is typically conducted in an instrument with a field emission guns (FEG) which is capable of producing high primary electron brightness and small spot size even at low accelerating potentials. To prevent charging of non-conductive specimens, operating conditions must be adjusted such that the incoming beam current is equal to sum of outcoming secondary and backscattered electrons currents a condition that is more often met at accelerating voltages of 0.3–4 kV.[citation needed]
The definition of video marketing is not complex. In fact, it’s rather simple: using video to promote or market your brand, product or service. A strong marketing campaign incorporates video into the mix. Customer testimonials, videos from live events, how-to videos, explainer videos, corporate training videos, viral (entertainment) videos — the list goes on.
If you own, manage, monetize, or promote online content via Google Search, this guide is meant for you. You might be the owner of a growing and thriving business, the webmaster of a dozen sites, the SEO specialist in a Web agency or a DIY SEO ninja passionate about the mechanics of Search : this guide is meant for you. If you're interested in having a complete overview of the basics of SEO according to our best practices, you are indeed in the right place. This guide won't provide any secrets that'll automatically rank your site first in Google (sorry!), but following the best practices outlined below will hopefully make it easier for search engines to crawl, index and understand your content.

Place strategic search phrases on pages. Integrate selected keywords into your website source code and existing content on designated pages. Make sure to apply a sug­gested guideline of one to three keywords/phrases per content page and add more pages to complete the list. Ensure that related words are used as a natural inclu­sion of your keywords. It helps the search engines quickly determine what the page is about. A natural approach to this works best. In the past, 100 to 300 words on a page was recommended. Many tests show that pages with 800 to 2,000 words can outperform shorter ones. In the end, the users, the marketplace, content and links will determine the popularity and ranking numbers.

Keeping up with the latest trends is a must for any business, but ignoring technology trends in the digital world is the matter of staying in business. Unfortunately, those trends (while easy enough to find mentioned online) are rarely explained well. There seems to be this mistaken idea that anyone who has an interest or need in the practice will just magically get the jargon. As we all know, that is one superpower that doesn’t exist in the real world.


This method requires an SEM image obtained in oblique low angle lighting. The grey-level is then interpreted as the slope, and the slope integrated to restore the specimen topography. This method is interesting for visual enhancement and the detection of the shape and position of objects ; however the vertical heights cannot usually be calibrated, contrary to other methods such as photogrammetry.[41]
Lastly, 2018 has brought about a penchant for the authentic and raw. According to HubSpot Research, consumers and customers actually prefer lower quality, “authentic” video over high-quality video that seems artificial and inauthentic. What does this mean for you? That video is within reach for businesses of virtually any size — team and budget, alike.
To create an effective DMP, a business first needs to review the marketplace and set 'SMART' (Specific, Measurable, Actionable, Relevant and Time-Bound) objectives.[60] They can set SMART objectives by reviewing the current benchmarks and key performance indicators (KPIs) of the company and competitors. It is pertinent that the analytics used for the KPIs be customised to the type, objectives, mission and vision of the company.[61][62]
You’ve launched an amazing product or service. Now what? Now, you need to get the word out. When done well, good PR can be much more effective and less expensive than advertising. Regardless of whether you want to hire a fancy agency or awesome consultant, make sure that you know what you’re doing and what types of ROI to expect. Relationships are the heart and soul of PR. This chapter will teach you how to ignore the noise and focus on substantive, measurable results.

He goes on to say that some of their videos might be seen as ‘edgy.’ However, HubSpot try not to be too conservative. Instead, they actively encourage video creators to be creative and take risks. Think your B2B audience can’t handle humour? Dharmesh makes an excellent point: the HubSpot audience is primarily B2B (but that won’t hold them back from being entertaining). Don’t feel constrained by what’s gone before you in your industry and don’t try to emulate your competitor’s stiff tone and yawnsome script. Stand out and take a chance on being funny.
The popularity of video also means that more content at the top of the funnel has to be in video format. In B2C it’s almost obvious. But B2B-people are people, too. Video content is more likely to keep the audience in the comfort zone, and they will not engage in system 2 thinking. System 1 autopilot mental state should lead to less critical thinking, less friction, and more conversions.
Of course, you can also include shorter content on YouTube as well, especially if your content is in YouTube’s ad format – viewers don’t have much patience to wait through ads on YouTube, and will often skip ads as soon as they are able. This is your opportunity to use the short-form content you’ve created that jumps immediately into your message and entices viewers to keep watching right from the first second. https://www.youtube.com/watch?v=e29F5n3ea0I&app=m

PPC advertising is a method of advertising on search engines like Google and Bing. As mentioned earlier, with PPC ads, you pay each time that ad is clicked on. PPC ads also exist on social media platforms like Instagram and Facebook as well. However, if you're going to engage in PPC advertising, it's important that you determine conversion rates by using tracking pixels.
Email marketing is the practice of nurturing leads and driving sales through email communications with your customers. Like social media, the goal is to remind users that you’re here and your product is waiting. Unlike social media, however, you can be a lot more aggressive with your sales techniques, as people expect that email marketing will contain offers, product announcements and calls to action.
Video advertising is becoming more and more affordable and widespread. Video adoption grows partly because advances in technology but also because it’s easy to spread across the globe. Making marketing videos for your business requires creativity and knowledge of human psychology. The cocktail of these components makes it possible to create real miracles of advertising at minimal cost. http://youtube.com/watch?feature=player_embedded&v=7bNPg8UbhaE
Completion rate: Completion rate is the number of people who completed your video divided by the number of people who played it. Completion rate, and other engagement metrics, are a great way to gauge a viewer’s reaction to your video. Do you have a low completion rate? Are people all dropping off at a certain point? This might be a sign that your video content is not resonating with your target audience.
Disney initially stated they wouldn’t exceed one million in donations, but ended up donating two million after the campaign blew up. #ShareYourEars campaign garnered 420 million social media impressions, and increased Make-A-Wish’s social media reach by 330%. The campaign is a powerful example of using an internet marketing strategy for a good cause. #ShareYourEars raised brand awareness, cultivated a connected online community, and positively affected Disney’s brand image.

I liken this to a paradoxical Catch-22 scenario, because it seems like without one you can't have the other. It takes money to drive traffic, but it takes traffic to make money. So don't make the mistake that millions of other online marketers make around the world. Before you attempt to scale or send any semblance of traffic to your offers, be sure to split-test things to oblivion and determine your conversion rates before diving in headfirst.
In a typical SEM, an electron beam is thermionically emitted from an electron gun fitted with a tungsten filament cathode. Tungsten is normally used in thermionic electron guns because it has the highest melting point and lowest vapor pressure of all metals, thereby allowing it to be electrically heated for electron emission, and because of its low cost. Other types of electron emitters include lanthanum hexaboride (LaB
The winners of the auction are generally determined by something called ad rank—a rank that considers the maximum bid set by each advertiser, which can range from pennies to unlimited (within certain restrictions), and an ad’s Quality Score. Other factors that influence an auction include the type of device being used, the searcher’s language preferences, their location, and the time of day.
The allure of so-called internet riches is nothing new. At every bend and turn in a gauntlet of online gurus, you'll find internet marketers looking to hype up this supposed dream of making money online or earning passive income while kicking up your feet and letting the cash roll in. While internet marketing doesn't quite work that way, in that you actually do have to put in the work, it isn't too difficult to separate the proverbial men from the boys when it comes to the real online earners.
After your site has been built out, creating a social media presence is the best second step for most businesses. All businesses should have a Facebook Page that’s fully fleshed out with plenty of information about your business. Depending on your audience, you can also start a Twitter, Instagram, and/or Pinterest account. Social media is a long-term commitment that requires frequently updating and monitoring, but it’s one of the best ways to build an online community around your business.

photogrammetry is the most metrologically accurate method to bring the third dimension to SEM images[41]. Contrary to photometric methods (next paragraph), photogrammetry calculates absolute heights using triangulation methods. The drawbacks are that it works only if there is a minimum texture, and it requires two images to be acquired from two different angles, which implies the use of a tilt stage. (Photogrammetry is a software operation that calculates the shift (or "disparity") for each pixel, between the left image and the right image of the same pair. Such disparity reflects the local height).
The SEM is routinely used to generate high-resolution images of shapes of objects (SEI) and to show spatial variations in chemical compositions: 1) acquiring elemental maps or spot chemical analyses using EDS, 2)discrimination of phases based on mean atomic number (commonly related to relative density) using BSE, and 3) compositional maps based on differences in trace element "activitors" (typically transition metal and Rare Earth elements) using CL. The SEM is also widely used to identify phases based on qualitative chemical analysis and/or crystalline structure. Precise measurement of very small features and objects down to 50 nm in size is also accomplished using the SEM. Backescattered electron images (BSE) can be used for rapid discrimination of phases in multiphase samples. SEMs equipped with diffracted backscattered electron detectors (EBSD) can be used to examine microfabric and crystallographic orientation in many materials.
Your iPhone might do a great job of focusing on the subject when you take photos, when when it comes to video, the camera will continue adjusting and re-adjusting as you move around the scene. To solve this problem, lock the exposure before you press record. Hold your finger down on the subject of the video until a yellow box appears with the words “AE/AF Lock”.
When you ask your friends which online video platform they use, the answer you probably hear the most is YouTube. YouTube is the largest video hosting platform, the second largest search platform after Google, and the third most visited website in the world. Every single day, people watch over five billion videos on YouTube. It’s also free to upload your videos to YouTube and optimize them for search.
White balance tells your camera the color temperature of the environment you’re shooting in. Different types of light have different colors. For example, incandescent bulbs (like what many people put in a lamp) have a very warm color. The florescent lights (if you’re reading this in an office, look up) are a little bit cooler. Daylight is cooler yet. Before you begin shooting, you have to adjust your camera’s white balance according to your setup.
Organic search (SEO): When you enter a keyword or phrase into a search engine like Google or Yahoo!, the organic results are displayed in the main body of the page.When your prospects search for information about your products and services, you want to rank highly in search engine results. By “optimizing” your site, you can improve your ranking for important search terms and phrases (“keywords”). You can also improve your rank by getting other important sites to link to yours. https://www.youtube.com/watch?feature=player_embedded&v=7bNPg8UbhaE
In some contexts, the term SEM is used exclusively to mean pay per click advertising,[2] particularly in the commercial advertising and marketing communities which have a vested interest in this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as search engine optimization and search retargeting.
But beyond video’s unique ability to convert like no other, the medium has become especially valuable to data-driven marketers. This is because you can track and measure audience engagement for video in a really meaningful way. You can tie your videos directly to the deals they are helping to influence and you can see which assets are actually resonating based on content engagement analytics. This is the reporting that marketing desperately needs to identify their most engaged leads faster and prove the value of game-changing initiatives.
As we’ve been told by the Google rater’s guide, we ideally want to focus upon building sites that raters might see as involving Expertise, Authoritativeness, and Trustworthiness. A recent Google patent told us that it might look at search results to gauge the authoritativeness of pages in search results, and if pages within those results don’t meet a specific threshold of authoritativeness, Google may perform a search on a related query to find other authoritative search results, which could then be blended into search results for that initial query.
Web design is a very technical field that requires high literacy in many different kinds of software, including image editing and website architecture programs. A designer should be comfortable with computer “languages” like HTML and stay up to date on new technological developments. The designer is also an artist, so he or she should also have a firm grasp on aesthetics, visual continuity, and image composition.
Prioritizing clicks refers to display click ads, although advantageous by being ‘simple, fast and inexpensive’ rates for display ads in 2016 is only 0.10 percent in the United States. This means one in a thousand click ads are relevant therefore having little effect. This displays that marketing companies should not just use click ads to evaluate the effectiveness of display advertisements (Whiteside, 2016).[42] https://www.youtube.com/watch?feature=player_embedded&v=e29F5n3ea0I
For example, what are the quality and quantity of the links that have been created over time? Are they natural and organic links stemming from relevant and high quality content, or are they spammy links, unnatural links or coming from bad link neighborhoods? Are all the links coming from the same few websites over time or is there a healthy amount of global IP diversification in the links?

PPC (paid search marketing): PPC (pay per click) advertising involves paying to have search engines display your website's promotion in or alongside search results. For example, Google's Adwords program will display your ad at the top or right side of the search results page (placement depends on many factors including keywords and quality of ad). Google will also feed your ads to websites running its Adsense program. There are other types of PPC marketing, such as Facebook Ads. In PPC advertising, you pay each time someone clicks on your offer. Paid search differs from organic search in that you're paying to have your website or offer displayed higher in search results.
