The scanning electron microscope (SEM) uses a focused beam of high-energy electrons to generate a variety of signals at the surface of solid specimens. The signals that derive from electron-sample interactions reveal information about the sample including external morphology (texture), chemical composition, and crystalline structure and orientation of materials making up the sample. In most applications, data are collected over a selected area of the surface of the sample, and a 2-dimensional image is generated that displays spatial variations in these properties. Areas ranging from approximately 1 cm to 5 microns in width can be imaged in a scanning mode using conventional SEM techniques (magnification ranging from 20X to approximately 30,000X, spatial resolution of 50 to 100 nm). The SEM is also capable of performing analyses of selected point locations on the sample; this approach is especially useful in qualitatively or semi-quantitatively determining chemical compositions (using EDS), crystalline structure, and crystal orientations (using EBSD). The design and function of the SEM is very similar to the EPMA and considerable overlap in capabilities exists between the two instruments.
Within your channel itself, you can also organize videos into playlists, making it easy for your audience to search within your content. As a social platform, viewers can engage with your videos by liking and commenting on them, providing you another chance to interact with your audience. YouTube also offers a variety of advertising options for more sophisticated targeting.
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.
Now that you’ve attracted video viewers and website visitors, the next step is to convert these visitors into leads. With most inbound marketing content, this means collecting some sort of contact information via a form. Video can aid this process by visualizing a solution to the buyer’s problem, whether that’s before the form on a landing page or as the offer itself. Overall, the goal of this kind of video is to educate and excite.
In order to engage customers, retailers must shift from a linear marketing approach of one-way communication to a value exchange model of mutual dialogue and benefit-sharing between provider and consumer.[21] Exchanges are more non-linear, free flowing, and both one-to-many or one-on-one.[5] The spread of information and awareness can occur across numerous channels, such as the blogosphere, YouTube, Facebook, Instagram, Snapchat, Pinterest, and a variety of other platforms. Online communities and social networks allow individuals to easily create content and publicly publish their opinions, experiences, and thoughts and feelings about many topics and products, hyper-accelerating the diffusion of information.[22] http://m.www.youtube.com/embed/e29F5n3ea0I
Search engines are a powerful channel for connecting with new audiences. Companies like Google and Bing look to connect their customers with the best user experience possible. Step one of a strong SEO strategy is to make sure that your website content and products are the best that they can be. Step 2 is to communicate that user experience information to search engines so that you rank in the right place. SEO is competitive and has a reputation of being a black art. Here’s how to get started the right way.
To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots (usually ). When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam.[45]
There is limited real estate for the top positions in organic search results. With the amount of content on the web today and the number of competitors you have, it can be hard to get in a top position, even despite your best efforts. If you’re a new business or an existing one trying to build your online presence, SEM/PPC advertising can get you in front of highly targeted customers.

View count: View count is the number of times your video has been viewed — also referred to as reach. This metric is great to track if your goal is to increase brand awareness and have your content seen by as many people as possible. However, it’s important to remember that every video hosting platform measures a view differently. For example, a view on YouTube is 30 seconds while a view on Facebook is only 3 seconds. Be sure to read the fine print before reporting on your video view count.
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

A disadvantage of digital advertising is the large amount of competing goods and services that are also using the same digital marketing strategies. For example, when someone searches for a specific product from a specific company online, if a similar company uses targeted advertising online then they can appear on the customer's home page, allowing the customer to look at alternative options for a cheaper price or better quality of the same product or a quicker way of finding what they want online.
ESEM is especially useful for non-metallic and biological materials because coating with carbon or gold is unnecessary. Uncoated Plastics and Elastomers can be routinely examined, as can uncoated biological samples. Coating can be difficult to reverse, may conceal small features on the surface of the sample and may reduce the value of the results obtained. X-ray analysis is difficult with a coating of a heavy metal, so carbon coatings are routinely used in conventional SEMs, but ESEM makes it possible to perform X-ray microanalysis on uncoated non-conductive specimens; however some specific for ESEM artifacts are introduced in X-ray analysis. ESEM may be the preferred for electron microscopy of unique samples from criminal or civil actions, where forensic analysis may need to be repeated by several different experts.

Small business owners sometimes think that search engine marketing (SEM), also known as pay-per-click advertising (PPC), is not lucrative option for them. They may think they can’t afford it, or that their online presence is not important if they are a local or service-based business. The truth is, as search engines have undeniably become a part of our lifestyles as consumers, there are many ways to leverage them for businesses of any size. This post will introduce you to the basics and benefits of search engine marketing (SEM).
Search engines find and catalog web pages through spidering (also known as webcrawling) software. Spidering software "crawls" through the internet and grabs information from websites which is used to build search engine indexes. Unfortunately, not all search engine spidering software works the same way, so what gives a page a high ranking on one search engine may not necessarily give it a high ranking on another. Note that rather than waiting for a search engine to discover a newly created page, web designers can submit the page directly to search engines for cataloging.

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!

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

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. https://www.youtube.com/watch?v=7bNPg8UbhaE

In 2007, Google announced a campaign against paid links that transfer PageRank.[29] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat nofollowed links in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[30] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated Javascript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and Javascript.[31] https://youtube.com/embed/7bNPg8UbhaE
