A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample. The electron beam is scanned in a raster scan pattern, and the position of the beam is combined with the detected signal to produce an image. SEM can achieve resolution better than 1 nanometer. Specimens are observed in high vacuum in conventional SEM, or in low vacuum or wet conditions in variable pressure or environmental SEM, and at a wide range of cryogenic or elevated temperatures with specialized instruments.[1]

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.
It is important for a firm to reach out to consumers and create a two-way communication model, as digital marketing allows consumers to give back feed back to the firm on a community based site or straight directly to the firm via email.[24] Firms should seek this long term communication relationship by using multiple forms of channels and using promotional strategies related to their target consumer as well as word-of mouth marketing.[24] https://www.youtube.com/v/7bNPg8UbhaE&feature=kp
SEM search placements include an “Ad” designation. SEO does not. Search results that appear as a result of SEM or SEO look different on SERPs. Paid ads that receive placement through SEM tactics are often identified as an ad (e.g., by an icon appearing next to the placement), whereas the search results that appear as a result of organic SEO are not marked in such manner.
With video content marketing, businesses find that certain metrics used to determine the success of web campaigns improve drastically. Dwell time is the most obvious, as engaging video content will likely keep visitors around for longer. 57 percent of retail brands said they notice average order values increase when users watch just one video they’ve produced and sales totals double when people have watched 10 or more videos.
Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches.[62] In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007.[63] As of 2006, Google had an 85–90% market share in Germany.[64] While there were hundreds of SEO firms in the US at that time, there were only about five in Germany.[64] As of June 2008, the marketshare of Google in the UK was close to 90% according to Hitwise.[65] That market share is achieved in a number of countries. https://m.youtube.com/watch?feature=player_embedded&v=e29F5n3ea0I

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
"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
