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.
When writing this guide, we reached out to the marketer community to collect case studies and learnings about creative marketing strategies. Most of these examples are included throughout the guide, but some didn’t quite fit. So we included those loose ends here, from the perspective of four awesome marketers. What better way to wrap up this guide than with you, our community?
We still seem to have PageRank as an important ranking factor from Google, but have been told that Google is using a machine learning approach called RankBrain. The focus of this RankBrain approach is to help the search engine understand the meaning of queries better, and provide answers that (still) focus upon meeting the situational and informational needs of searchers.
Fixation is usually performed by incubation in a solution of a buffered chemical fixative, such as glutaraldehyde, sometimes in combination with formaldehyde[20][21][22] and other fixatives,[23] and optionally followed by postfixation with osmium tetroxide.[20] The fixed tissue is then dehydrated. Because air-drying causes collapse and shrinkage, this is commonly achieved by replacement of water in the cells with organic solvents such as ethanol or acetone, and replacement of these solvents in turn with a transitional fluid such as liquid carbon dioxide by critical point drying.[24] The carbon dioxide is finally removed while in a supercritical state, so that no gas–liquid interface is present within the sample during drying. https://www.youtube.com/watch?v=7bNPg8UbhaE&app=desktop
Paid search is precise and agile. You get the searchers you want, but you pay for that convenience. SEO is technically free, but it takes research and effort to make sure your net is in the right place and catching the right kind of fish. It also takes longer to move a net than to pack up your tackle and try another lake, and the same is true for drastically changing an SEO campaign versus changing a paid search campaign.
SEM on the other hand, encompases any strategy that involves gaining traffic from search engines like Google and Bing. Along with SEO being a tool, SEM encompases paid placement such as pay-per-click (PPC) or cost-per-click (CPC), paid inclusion that simply gets you ranked for a price, and of course traditional ads placed on SERPs. All of these subsets are unique and their tools perform different functions.
Often the line between pay per click advertising and paid inclusion is debatable. Some have lobbied for any paid listings to be labeled as an advertisement, while defenders insist they are not actually ads since the webmasters do not control the content of the listing, its ranking, or even whether it is shown to any users. Another advantage of paid inclusion is that it allows site owners to specify particular schedules for crawling pages. In the general case, one has no control as to when their page will be crawled or added to a search engine index. Paid inclusion proves to be particularly useful for cases where pages are dynamically generated and frequently modified.
When referring to the homepage, a trailing slash after the hostname is optional since it leads to the same content ("https://example.com/" is the same as "https://example.com"). For the path and filename, a trailing slash would be seen as a different URL (signaling either a file or a directory), for example, "https://example.com/fish" is not the same as "https://example.com/fish/".
This SEO tutorial teaches you a "beat the leader" approach to search engine ranking with SEO tips that have worked for our digital marketing clients. To see what Google or Bing thinks is best for any specific attribute, we look at the sites they are currently rewarding — the top-ranked results. Once you know what structural and content choices worked for the "leaders," you can do even better by making your pages the "least imperfect"!

Marketers understand that this "hunt mode" means that the searcher may very well be at the beginning, middle, or end stages of the buying cycle. When someone is researching a product or service to satisfy an immediate or future need they are in an unusual state: they desire relevant information and are open to digesting and acting on the information at their fingertips, all made possible by a search engine. This makes search engine results some of the best sources of targeted traffic, whether this traffic originates from "organic" unpaid search listings or paid advertising listings.
In addition to helping you find keywords you should be bidding on, thorough keyword research can also help you identify negative keywords – search terms that you should exclude from your campaigns. Negative keywords aren’t terms with negative connotations, but rather irrelevant terms that are highly unlikely to result in conversions. For example, if you sell ice cream, you might want to exclude the keyword “ice cream recipes”, as users searching for ice cream recipes are unlikely to be in the market for your product.
The answer, at its basis, is largely what I convey in a great majority of my books about search engine optimization and online marketing. It all boils down to one simple concept: add tremendous amounts of value to the world. The more value you add, the more successful you become. Essentially, you have to do the most amount of work (initially at least) for the least return. Not the other way around.
There are ten essential types of marketing that can be done online. Some of these can be broken down into organic marketing and others can be categorized as paid marketing. Organic, of course, is the allure of marketing professionals from around the planet. It's free and its unencumbered traffic that simply keeps coming. Paid marketing, on the other hand, is still a very attractive proposition as long as the marketing pays for itself by having the right type of offer that converts.
The fact is, YouTube is the second biggest search engine, next to Google. Yet in a recent study, 87% of marketers said they planned on placing video ads on Facebook, compared with 81.5% on YouTube. Don’t make the mistake of valuing one over the other, even with fancy numbers like Facebook’s 4 billion video views: after all, Facebook videos autoplay, so any view that lasts at least 3 seconds is counted as a full view. 4 billion is an impressive number no matter how you look at it, but keep the whole story in mind.

Before launching any marketing campaign, it’s important to determine your primary video goal. This could be to increase brand awareness, engagement, or even conversions for a free trial. It’s crucial to pick out just one or two goals for each video. When you define more than that, your video will seem unfocused, making it difficult for viewers to determine what they should do next.


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.
After you’ve determined the type of music you need, it’s time to start analyzing potential songs. Consider the song’s pacing. Songs with a steady rhythm are easy to change to suit your video style. Hoping to include your favorite, Top 40 hit? Popular, radio songs are usually structured in 4-5 parts and can be difficult to transition. Try to choose simple songs that are easy to loop. If you’re looking for an instrumental song, be sure to find something that was recorded with real instruments. Songs made with digital samples can make your video feel unprofessional and out of date.
There’s obviously a huge number of reasons why a website might link to another and not all of them fit into the categories above. A good rule of thumb on whether a link is valuable is to consider the quality of referral traffic (visitors that might click on the link to visit your website). If the site won’t send any visitors, or the audience is completely unrelated and irrelevant, then it might not really be a link that’s worth pursuing.

Understand that whatever you're going to do, you'll need traffic. If you don't have any money at the outset, your hands will be tied no matter what anyone tells you. The truth is that you need to drive traffic to your offers if you want them to convert. These are what we call landing pages or squeeze pages. This is where you're coming into contact with the customers, either for the first time or after they get to know you a little bit better.

SEM is not a camera and the detector is not continuously image-forming like a CCD array or film. Unlike in an optical system, the resolution is not limited by the diffraction limit, fineness of lenses or mirrors or detector array resolution. The focusing optics can be large and coarse, and the SE detector is fist-sized and simply detects current. Instead, the spatial resolution of the SEM depends on the size of the electron spot, which in turn depends on both the wavelength of the electrons and the electron-optical system that produces the scanning beam. The resolution is also limited by the size of the interaction volume, the volume of specimen material that interacts with the electron beam. The spot size and the interaction volume are both large compared to the distances between atoms, so the resolution of the SEM is not high enough to image individual atoms, as is possible with transmission electron microscope (TEM). The SEM has compensating advantages, though, including the ability to image a comparatively large area of the specimen; the ability to image bulk materials (not just thin films or foils); and the variety of analytical modes available for measuring the composition and properties of the specimen. Depending on the instrument, the resolution can fall somewhere between less than 1 nm and 20 nm. As of 2009, The world's highest resolution conventional (≤30 kV) SEM can reach a point resolution of 0.4 nm using a secondary electron detector.[30] https://youtube.com/watch?v=e29F5n3ea0I&app=desktop
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.
Tripods range tremendously in price, and the quality of your tripod should depend on the level of camera and lens you have. If you’re shooting with your phone, you can get by with a table mount like the Arkon Tripod Mount or a full-size tripod like the Acuvar 50” Aluminum Tripod. For a DSLR, Manfrotto makes a variety of trustworthy tripods starting with the Manfrotto BeFree and increasing in quality and price from there.

Vlogging has become huge on Youtube. Vloggers film multiple aspects of their daily lives whether they be mundane, like preparing breakfast, or exciting, like going on vacation. Businesses and entrepreneurs have slowly been invading the vlogging world lately; and in 2019, you can expect this practice to become even more popular. Reason? Vlogging gives your viewers a peek into your life and can help you form a better connection with your audience.
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.
Synthetic replicas can be made to avoid the use of original samples when they are not suitable or available for SEM examination due to methodological obstacles or legal issues. This technique is achieved in two steps: (1) a mold of the original surface is made using a silicone-based dental elastomer, and (2) a replica of the original surface is obtained by pouring a synthetic resin into the mold.[18]
Website saturation and popularity, or how much presence a website has on search engines, can be analyzed through the number of pages of the site that are indexed by search engines (saturation) and how many backlinks the site has (popularity). It requires pages to contain keywords people are looking for and ensure that they rank high enough in search engine rankings. Most search engines include some form of link popularity in their ranking algorithms. The following are major tools measuring various aspects of saturation and link popularity: Link Popularity, Top 10 Google Analysis, and Marketleap's Link Popularity and Search Engine Saturation.
Search engines use complex mathematical algorithms to guess which websites a user seeks. In this diagram, if each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Websites getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded.
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.
Influencer marketing: Important nodes are identified within related communities, known as influencers. This is becoming an important concept in digital targeting. It is possible to reach influencers via paid advertising, such as Facebook Advertising or Google Adwords campaigns, or through sophisticated sCRM (social customer relationship management) software, such as SAP C4C, Microsoft Dynamics, Sage CRM and Salesforce CRM. Many universities now focus, at Masters level, on engagement strategies for influencers.

Companies that employ overly aggressive techniques can get their client websites banned from the search results. In 2005, the Wall Street Journal reported on a company, Traffic Power, which allegedly used high-risk techniques and failed to disclose those risks to its clients.[15] Wired magazine reported that the same company sued blogger and SEO Aaron Wall for writing about the ban.[16] Google's Matt Cutts later confirmed that Google did in fact ban Traffic Power and some of its clients.[17]
"Convert" videos may include a webinar filled with tactical advice, product demos sent via email, landing page promotional videos, case studies, or more in-depth explainer and how-to videos. For example, while an "attract" video might provide a quick tip for nailing a sales pitch, a "convert" video could be an animated explainer video that breaks down the inbound sales methodology. https://m.youtube.com/embed/e29F5n3ea0I
Internet Live Stats claims that there are over 66,000 searches per second on Google each day. (Note that this is figure was taken at the time of writing – if you click on the link you’ll likely find a different number, as data from this source is collected in real time.) That’s a lot of activity for any given business to compete with and is why SEO is such an important (but tricky) area of digital marketing to know. 
Search engine marketing, or SEM, is meant to cover both search engine optimization (SEO) and paid search, also known as PPC (pay-per-click) or CPC (cost-per-click). From enhancing content with organic keywords to making sure a landing page meets Google AdWords quality guidelines, any optimization for the web traditionally fell under the umbrella of SEM. Over time, though, SEM has come to mean something much more specific. Popular usage now covers paid search exclusively, with SEO separated out. SEM still refers occasionally to paid search with a minor emphasis on SEO, but that’s even rarer than using the term properly. For clarity’s sake, I’ll replace SEM with “paid search” for the rest of this post. http://www.youtube.com/v/e29F5n3ea0I&feature=share
You may not want certain pages of your site crawled because they might not be useful to users if found in a search engine's search results. If you do want to prevent search engines from crawling your pages, Google Search Console has a friendly robots.txt generator to help you create this file. Note that if your site uses subdomains and you wish to have certain pages not crawled on a particular subdomain, you'll have to create a separate robots.txt file for that subdomain. For more information on robots.txt, we suggest this Webmaster Help Center guide on using robots.txt files13.
SEM on the other hand, encompases any strategy that involves gaining traffic from search engines like Google and Bing. Along with SEO being a tool, SEM encompases paid placement such as pay-per-click (PPC) or cost-per-click (CPC), paid inclusion that simply gets you ranked for a price, and of course traditional ads placed on SERPs. All of these subsets are unique and their tools perform different functions.
Jim Boykin blows my mind every time I talk to him. I have been doing SEO for 15 years and yet I am amazed at the deep stuff Jim comes up with. Simply amazing insights and always on the cutting edge. He cuts through the BS and tells you what really works and what doesn't. After our chat, I grabbed my main SEO guy and took him to lunch and said "you have to help me process all this new info..." I was literally pacing around the room...I have so many new ideas to experiment with that I would never have stumbled onto on my own. He is the Michael Jordan or the Jerry Garcia of links...Hope to go to NY again to Jim's amazing SEO classes. Thanks Jim! Michael G.
We combine our sophisticated Search Engine Optimization skills with our ORM tools such as social media, social bookmarking, PR, video optimization, and content marketing to decrease the visibility of potentially damaging content. We also work with our clients to create rebuttal pages, micro-sites, positive reviews, social media profiles, and blogs in order to increase the volume of positive content that can be optimized for great search results.
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
Internet marketing, or online marketing, refers to advertising and marketing efforts that use the Web and email to drive direct sales via electronic commerce, in addition to sales leads from websites or emails. Internet marketing and online advertising efforts are typically used in conjunction with traditional types of advertising such as radio, television, newspapers and magazines.
Google's core algorithms and its propensity to shroud its data in layers of obscurity is not something new. However, it is critical to any understanding of marketing on the internet simply because this visibility is at the heart of everything else that you do. Forget about social media and other forms of marketing for the time being. Search engine optimization (SEO) offers up the proverbial key to near-limitless amounts of traffic on the web.
Was reviewing some competitive data and thought this was pretty interesting. I ran a batch analysis on Ahrefs of competitors. See attached screenshot. With just 603 backlinks, Our site is ranking up there with sites with 2x, 3x, 10x the number of backlinks/unique ips. Guessing some of this authority is coming from the backlinks program and general good quality of those links. Hard to speculate but nice to see. Ben R. http://www.youtube.com/e/7bNPg8UbhaE
