The SEM is routinely used to generate high-resolution images of shapes of objects (SEI) and to show spatial variations in chemical compositions: 1) acquiring elemental maps or spot chemical analyses using EDS, 2)discrimination of phases based on mean atomic number (commonly related to relative density) using BSE, and 3) compositional maps based on differences in trace element "activitors" (typically transition metal and Rare Earth elements) using CL. The SEM is also widely used to identify phases based on qualitative chemical analysis and/or crystalline structure. Precise measurement of very small features and objects down to 50 nm in size is also accomplished using the SEM. Backescattered electron images (BSE) can be used for rapid discrimination of phases in multiphase samples. SEMs equipped with diffracted backscattered electron detectors (EBSD) can be used to examine microfabric and crystallographic orientation in many materials.
Another example when the “nofollow" attribute can come handy are widget links. If you are using a third party's widget to enrich the experience of your site and engage users, check if it contains any links that you did not intend to place on your site along with the widget. Some widgets may add links to your site which are not your editorial choice and contain anchor text that you as a webmaster may not control. If removing such unwanted links from the widget is not possible, you can always disable them with “nofollow" attribute. If you create a widget for functionality or content that you provide, make sure to include the nofollow on links in the default code snippet.
Look at your short- and long-term goals to choose whether to focus on organic or paid search (or both). It takes time to improve your organic search rankings, but you can launch a paid search campaign tomorrow. However, there are other considerations: the amount of traffic you need, your budget, and your marketing objectives. Once you’ve reviewed the pros and cons, you can select the search strategy that’s right for you.
There are plenty of tactics you can use to ensure your videos get found easier in search engines. The first thing you should do to derive the maximum SEO value from your video (before you upload your video to any sharing sites) is to host it on your own domain. It’s also important to enable embedding on your video as this will help you increase the likelihood of receiving inbound marketing links. Oh and don’t forget to avail of video sitemaps – in this nifty document Google explains how to create a video sitemap with ease.
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?

Google's search engine marketing is one of the western world's marketing leaders, while its search engine marketing is its biggest source of profit.[17] Google's search engine providers are clearly ahead of the Yahoo and Bing network. The display of unknown search results is free, while advertisers are willing to pay for each click of the ad in the sponsored search results.
Paid Search: The advantage of paid search is that you can have your website listed on the first pages in a prominent spot on Google and other search engines. However, showing up is only part of the process. You need to create an ad that not only leads to clicks, but to sales or whatever result you're looking for. If you don't know what you're doing, it's possible to write an ad that people are drawn to and click on, however, you don't make sales. Since you pay per click, and clicks can add up quickly, you can lose money.
An omni-channel approach not only benefits consumers but also benefits business bottom line: Research suggests that customers spend more than double when purchasing through an omni-channel retailer as opposed to a single-channel retailer, and are often more loyal. This could be due to the ease of purchase and the wider availability of products.[24]
Entertainment — The Internet is a plethora of things to do. Some are looking for videos. Others are looking for games. Many are entertained by new stories. Others like financial calculators. Others want to learn something new. Think about what kind of entertainment your target is looking for. Relate it back to your brand. That’s a great way to use SEM to connect.
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.
If you're not using internet marketing to market your business you should be. An online presence is crucial to helping potential clients and customer find your business - even if your business is small and local. (In 2017, one third of all mobile searches were local and local search was growing 50% faster than mobile searches overall.) Online is where the eyeballs are so that's where your business needs to be. 
Make it as easy as possible for users to go from general content to the more specific content they want on your site. Add navigation pages when it makes sense and effectively work these into your internal link structure. Make sure all of the pages on your site are reachable through links, and that they don't require an internal "search" functionality to be found. Link to related pages, where appropriate, to allow users to discover similar content.
Conventional SEM requires samples to be imaged under vacuum, because a gas atmosphere rapidly spreads and attenuates electron beams. As a consequence, samples that produce a significant amount of vapour, e.g. wet biological samples or oil-bearing rock, must be either dried or cryogenically frozen. Processes involving phase transitions, such as the drying of adhesives or melting of alloys, liquid transport, chemical reactions, and solid-air-gas systems, in general cannot be observed. Some observations of living insects have been possible however.[31]
The concept behind Search Engine Marketing is quite simple: when a consumer or business person searches the Web through either a text box or by clicking through a directory hierarchy, he or she is in "hunt mode." This psychological state is unique because it signals to the search engine (and to marketers) that the person is looking for information, often of a direct or indirect commercial nature.
SEO should be a core tactic in any marketing strategy. While it might seem difficult to understand at first, as long as you find the right course, book or audiobook, and devote your time to learning, you'll be in good shape. Considering that there are over 200+ ranking factors in Google's current algorithms, learning, digesting and successfully implementing good SEO tactics is essential to the success of your website or blog.

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.
