Magnification in an SEM can be controlled over a range of about 6 orders of magnitude from about 10 to 500,000 times. Unlike optical and transmission electron microscopes, image magnification in an SEM is not a function of the power of the objective lens. SEMs may have condenser and objective lenses, but their function is to focus the beam to a spot, and not to image the specimen. Provided the electron gun can generate a beam with sufficiently small diameter, an SEM could in principle work entirely without condenser or objective lenses, although it might not be very versatile or achieve very high resolution. In an SEM, as in scanning probe microscopy, magnification results from the ratio of the dimensions of the raster on the specimen and the raster on the display device. Assuming that the display screen has a fixed size, higher magnification results from reducing the size of the raster on the specimen, and vice versa. Magnification is therefore controlled by the current supplied to the x, y scanning coils, or the voltage supplied to the x, y deflector plates, and not by objective lens power.
With 360° videos, viewers “scroll” around to see content from every angle — as if they were physically standing within the content. This spherical video style allows viewers to experience a location or event, such as exploring Antarctica or meeting a hammerhead shark. VR allows viewers to navigate and control their experience. These videos are usually viewed through devices such as Oculus Rift or Google Cardboard.
An authority website is a site that is trusted by its users, the industry it operates in, other websites and search engines. Traditionally a link from an authority website is very valuable, as it’s seen as a vote of confidence. The more of these you have, and the higher quality content you produce, the more likely your own site will become an authority too.
As an alternative to simply replacing each grey level by a color, a sample observed by an oblique beam allows researchers to create an approximative topography image (see further section "Photometric 3D rendering from a single SEM image"). Such topography can then be processed by 3D-rendering algorithms for a more natural rendering of the surface texture

You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.


In fact, according to a Google-commissioned Nielsen study, on mobile alone, in an average week, YouTube reaches more adults 18-plus during prime time than any cable network does. And, with people freaking out over the mere idea that Netflix has started testing ads on its platform, more companies will be turning to Youtube next year to get their video advertisements in front of a large audience which doesn't mind seeing ads ahead of video content. https://www.youtube.com/watch?feature=youtube_gdata&v=7bNPg8UbhaE

What is ​search engine optimization, then? It's not secrets or tricks — just ranking methodologies to follow in order to help a site that offers value to users beat the competition in search results. Today, you must be committed not just to optimizing your domain, but also to making it a quality site that attracts links naturally and is worthy of ranking. https://youtube.com/e/7bNPg8UbhaE
If your video is product- or service-centric, potential customers have no chance at feeling some connection with your video. Your product or service just helps them accomplish a job that they need to complete! But, if you take a human-centric approach, you have a chance to grab their attention even when they are not explicitly looking to solve a problem. They can enjoy your story and learn a little more about your brand without feeling like they are watching an advertisement. https://www.youtube.com/watch?v=e29F5n3ea0I&feature=kp

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. http://m.www.youtube.com/watch?feature=player_embedded&v=7bNPg8UbhaE
Paid channel marketing is something you’ve probably come across in some form or another. Other names for this topic include Search Engine Marketing (SEM), online advertising, or pay-per-click (PPC) marketing. Very often, marketers use these terms interchangeably to describe the same concept — traffic purchased through online ads. Marketers frequently shy away from this technique because it costs money. This perspective will put you at a significant disadvantage. It’s not uncommon for companies to run PPC campaigns with uncapped budgets. Why? Because you should be generating an ROI anyway. This chapter walks through the basics of how.
Next, consider your audience and the overall mood for your production. Are you targeting a small audience that will appreciate the newest, underground hip-hop track, or do you need something that will appeal to many demographics? Are you creating a practical product tutorial or an upbeat event recap? Be sure to choose music that enhances the overall tone of your video. https://www.youtube.com/embed/7bNPg8UbhaE

As you know, other social media sites also offer a video experience, including Vine, Instagram, and Twitter. These sites are perfect for even shorter content, since Vine videos can only be 6 seconds long, while Instagram Twitter videos can be around 15 to 20 seconds. This may sound scary, but short video lengths force marketers to practice the art of brevity; if the content isn’t fundamental to your message, what’s it doing in there? The human attention span is considered to be only 8 seconds long, so you can look at it this way: your short videos are bound to hold most people’s attention til the end!
In the section on preparing talent, we discussed how to record your script in short sections. If the editor were to stitch these sections together side-by-side, the subject’s face and hands might abruptly switch between clips. This is called a jump cut, and for editors, it poses an interesting challenge. Thankfully, this is where b-roll comes in handy, to mask these jump cuts.
Keywords can also guide other promotional efforts—even business decisions. In the “Beginner’s Guide to SEO,” the team at Moz wrote: “The usefulness of this intelligence cannot be overstated; with keyword research, you can predict shifts in demand, respond to changing market conditions, and produce the products, services, and content that web searchers are actively seeking.”
Digital marketing planning is a term used in marketing management. It describes the first stage of forming a digital marketing strategy for the wider digital marketing system. The difference between digital and traditional marketing planning is that it uses digitally based communication tools and technology such as Social, Web, Mobile, Scannable Surface.[57][58] Nevertheless, both are aligned with the vision, the mission of the company and the overarching business strategy.[59] https://youtube.com/watch?v=e29F5n3ea0I

Robots.txt is not an appropriate or effective way of blocking sensitive or confidential material. It only instructs well-behaved crawlers that the pages are not for them, but it does not prevent your server from delivering those pages to a browser that requests them. One reason is that search engines could still reference the URLs you block (showing just the URL, no title or snippet) if there happen to be links to those URLs somewhere on the Internet (like referrer logs). Also, non-compliant or rogue search engines that don't acknowledge the Robots Exclusion Standard could disobey the instructions of your robots.txt. Finally, a curious user could examine the directories or subdirectories in your robots.txt file and guess the URL of the content that you don't want seen.
Search Engine Marketing, or SEM, is the method of gaining traffic by purchasing ads on search engines. It is also called paid search and sometimes referred to as CPC (cost-per-click) or PPC (pay-per-click) marketing, because most search ads are sold on a CPC / PPC basis. Like Search Engine Optimization (SEO), it relies on keywords that activate your results into the paid advertising section of the search results page.
In 2013, the Tenth Circuit Court of Appeals held in Lens.com, Inc. v. 1-800 Contacts, Inc. that online contact lens seller Lens.com did not commit trademark infringement when it purchased search advertisements using competitor 1-800 Contacts' federally registered 1800 CONTACTS trademark as a keyword. In August 2016, the Federal Trade Commission filed an administrative complaint against 1-800 Contacts alleging, among other things, that its trademark enforcement practices in the search engine marketing space have unreasonably restrained competition in violation of the FTC Act. 1-800 Contacts has denied all wrongdoing and is scheduled to appear before an FTC administrative law judge in April 2017.[29]
An Internet marketing campaign is not an isolated, one-off proposal. Any company that plans on using it once is certain to continue to use it. An individual who is knowledgeable about all aspects of an Internet marketing campaign and who has strong interpersonal skills is well-suited to maintain an ongoing managerial role on a dedicated marketing team.

Video advertising - This type of advertising in terms of digital/online means are advertisements that play on online videos e.g. YouTube videos. This type of marketing has seen an increase in popularity over time.[50] Online Video Advertising usually consists of three types: Pre-Roll advertisements which play before the video is watched, Mid-Roll advertisements which play during the video, or Post-Roll advertisements which play after the video is watched.[51] Post-roll advertisements were shown to have better brand recognition in relation to the other types, where-as "ad-context congruity/incongruity plays an important role in reinforcing ad memorability".[50] Due to selective attention from viewers, there is the likelihood that the message may not be received.[52] The main advantage of video advertising is that it disrupts the viewing experience of the video and therefore there is a difficulty in attempting to avoid them. How a consumer interacts with online video advertising can come down to three stages: Pre attention, attention, and behavioural decision.[53] These online advertisements give the brand/business options and choices. These consist of length, position, adjacent video content which all directly affect the effectiveness of the produced advertisement time,[50] therefore manipulating these variables will yield different results. Length of the advertisement has shown to affect memorability where-as longer duration resulted in increased brand recognition.[50] This type of advertising, due to its nature of interruption of the viewer, it is likely that the consumer may feel as if their experience is being interrupted or invaded, creating negative perception of the brand.[50] These advertisements are also available to be shared by the viewers, adding to the attractiveness of this platform. Sharing these videos can be equated to the online version of word by mouth marketing, extending number of people reached.[54] Sharing videos creates six different outcomes: these being "pleasure, affection, inclusion, escape, relaxation, and control".[50] As well, videos that have entertainment value are more likely to be shared, yet pleasure is the strongest motivator to pass videos on. Creating a ‘viral’ trend from mass amount of a brands advertisement can maximize the outcome of an online video advert whether it be positive or a negative outcome.
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. http://youtube.com/watch?v=e29F5n3ea0I&app=desktop
Not every single ad will appear on every single search. This is because the ad auction takes a variety of factors into account when determining the placement of ads on the SERP, and because not every keyword has sufficient commercial intent to justify displaying ads next to results. However, the two main factors that Google evaluates as part of the ad auction process are your maximum bid and the Quality Score of your ads.
Both require knowing your audience. To succeed at both strategies, you must have a good understanding of your audience and how they act. By using buyer personas and psychographic segmentation, you can get to know your audience, discover what their needs are, and what they are searching for. Then you can create valuable content that shows up when they go looking for solutions related to your brand.
Writing blog posts is especially effective for providing different opportunities to land on page one of search engines -- for instance, maybe your eyeglass store’s website is on page three of Google for “eyeglasses,” but your “Best Sunglasses of 2018” blog post is on page one, pulling in an impressive amount of traffic (over time, that blog post could also boost your overall website to page one).
Many blogging software packages automatically nofollow user comments, but those that don't can most likely be manually edited to do this. This advice also goes for other areas of your site that may involve user-generated content, such as guest books, forums, shout-boards, referrer listings, etc. If you're willing to vouch for links added by third parties (for example, if a commenter is trusted on your site), then there's no need to use nofollow on links; however, linking to sites that Google considers spammy can affect the reputation of your own site. The Webmaster Help Center has more tips on avoiding comment spam39, for example by using CAPTCHAs and turning on comment moderation.
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. http://youtube.com/embed/e29F5n3ea0I
For example: If you sell household electronics and your paid ad promotes your selection of noise-cancelling headphones, your landing page should feature your noise-cancelling headphones. Directing people to your homepage instead, where they’ll need to sift through your product categories or do another search, will lead to frustration and a poor chance of getting the sale. http://www.youtube.com/embed/7bNPg8UbhaE
