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.
For instance, you might use Facebook’s Lookalike Audiences to get your message in front of an audience similar to your core demographic. Or, you could pay a social media influencer to share images of your products to her already well-established community. Paid social media can attract new customers to your brand or product, but you’ll want to conduct market research and A/B testing before investing too much in one social media channel.
There are several ways to increase your social media video subscribers. Use video SEO to make it easier for target audiences to find your videos. Include attractive custom thumbnails to make your videos more enticing. Use end cards and annotations to include calls to action asking viewers to subscribe. You can also promote your videos on your website, landing pages or blog posts. And you can use influencer marketing to spread the word about your video content and gain new subscribers that way.
The impact on who you hire. If you’re looking for an SEO specialist and using SEM terminology, you’ll be inundated with applicants who have more experience with paid search than with SEO. You may also find an SEO pro with paid search experience, but I don’t recommend having a single person handle both. For the best results, you need to focus on one or the other. Some specialists can compartmentalize and not let paid and organic-keyword research taint each other, but many have trouble—upping the risk that your pair of keyword strategies will meld into one.
The fee structure is both a filter against superfluous submissions and a revenue generator. Typically, the fee covers an annual subscription for one webpage, which will automatically be catalogued on a regular basis. However, some companies are experimenting with non-subscription based fee structures where purchased listings are displayed permanently. A per-click fee may also apply. Each search engine is different. Some sites allow only paid inclusion, although these have had little success. More frequently, many search engines, like Yahoo!,[18] mix paid inclusion (per-page and per-click fee) with results from web crawling. Others, like Google (and as of 2006, Ask.com[19][20]), do not let webmasters pay to be in their search engine listing (advertisements are shown separately and labeled as such).
When they’re considering buying something and want to research their options, there’s a variety of methods used. Some of the top tactics are a search engine, visiting a company or product’s official website, looking at review websites, and watching videos. Video could easily be incorporated into every one of those places, giving your brand a better chance of convincing the consumer.

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.
Liis, I couldn’t agree more with everything you say here. It’s such a motivating stuff . I can’t believe how far video has come since the early YouTube days. Social video is now such an important tool to modern marketing that my clients keep asking for more. The results really speak for themselves. I also love how more and more tools pop up (like slide.ly/promo and wevideo.com) to help make videos more accessible and possible for brands and companies of all sizes, not just the big brands. It’s been an interesting journey watching video grow up until now, but, I can’t wait to see what the future of video marketing will look like.

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.
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.
Gaining Google's trust doesn't happen overnight. It takes time. Think about building up your relationship with anyone. The longer you know that person, the more likely that trust will solidify. So, the reasoning is, that if Google just met you, it's going to have a hard time trusting you. If you want Google to trust you, you have to get other people that Google already trusts, to vouch for you. This is also known as link-building.
In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[21] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer. https://m.youtube.com/watch?v=e29F5n3ea0I&feature=youtube_gdata

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]
SEO is an acronym for "search engine optimization" or "search engine optimizer." Deciding to hire an SEO is a big decision that can potentially improve your site and save time, but you can also risk damage to your site and reputation. Make sure to research the potential advantages as well as the damage that an irresponsible SEO can do to your site. Many SEOs and other agencies and consultants provide useful services for website owners, including:
We recently published an infographic on how powerful video will become. But the future has already arrived. This has been a full-on video revolution year for marketers. According to Wyzowl statistics, 63% of businesses have started using video content marketing. Out of those 82% of businesses feel video marketing is an important part of their strategy. Video is progressing rapidly and will reach new heights sooner than we think. This trend is fueled by 83% of businesses believing that video marketing gives them a good ROI.
The first commercial development of the ESEM in the late 1980s[32][33] allowed samples to be observed in low-pressure gaseous environments (e.g. 1–50 Torr or 0.1–6.7 kPa) and high relative humidity (up to 100%). This was made possible by the development of a secondary-electron detector[34][35] capable of operating in the presence of water vapour and by the use of pressure-limiting apertures with differential pumping in the path of the electron beam to separate the vacuum region (around the gun and lenses) from the sample chamber.
SEM search results have ad extensions. SEO search results have featured snippets. When comparing SEM vs. SEO, you’ll also find differences in the appearance of the search results. SEM search results may include ad extensions, which can add on additional links, phone numbers, and callouts. On the other hand, SEO results may appear with featured snippets in search.
7. Keyword research. Specific target keywords aren’t as important for SEO success as they used to be, now that Google search is fueled by semantic and contextual understanding, but you should still be able to identify both head keyword (short, high-volume keywords) and long-tail keyword (longer, conversational, low-volume keywords) targets to guide the direction of your campaign. http://m.youtu.be/7bNPg8UbhaE
