Nonconducting specimens may be imaged without coating using an environmental SEM (ESEM) or low-voltage mode of SEM operation. In ESEM instruments the specimen is placed in a relatively high-pressure chamber and the electron optical column is differentially pumped to keep vacuum adequately low at the electron gun. The high-pressure region around the sample in the ESEM neutralizes charge and provides an amplification of the secondary electron signal. Low-voltage SEM is typically conducted in an instrument with a field emission guns (FEG) which is capable of producing high primary electron brightness and small spot size even at low accelerating potentials. To prevent charging of non-conductive specimens, operating conditions must be adjusted such that the incoming beam current is equal to sum of outcoming secondary and backscattered electrons currents a condition that is more often met at accelerating voltages of 0.3–4 kV.
Search engine optimization is a key part of online marketing because search is one of the primary ways that users navigate the web. In 2014, over 2.5 trillion searches were conducted worldwide across search engines such as Google, Bing, Yahoo, Baidu, and Yandex. For most websites, traffic that comes from search engines (known as "natural" or "organic" traffic) accounts for a large portion of their total traffic.
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.
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.
Did you know that 85% of Facebook video is watched with no sound? Many people watch videos in places where they can't turn the sound up, or where there's background noise. Those are two important reasons why video captions matter. And, of course, video captions matter for accessibility. Include captions, and you will improve you click-through rate as those with hearing loss or impairment can still understand your video content. Captions also help with SEO by providing text that search engines can find.
Website ranking doesn't just come from what's on your website. Google, the number one search engine used today, uses a variety of other factors to rank websites. Things like your social media activity, appearances on other sites through interviews or guest blogging, and being listed as a resource on another site all increase your standing in Google's eyes.
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.
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. Wired magazine reported that the same company sued blogger and SEO Aaron Wall for writing about the ban. Google's Matt Cutts later confirmed that Google did in fact ban Traffic Power and some of its clients.
Did you know that 65% of your audience are visual learners? One of the most powerful methods you can use for video marketing is to educate your audience. And the great thing is that education comes in many forms. For example, you can teach your customers how to use your product or service and provide useful tips on how to make the most of it. Or you can create a webinar to showcase your industry knowledge, position your brand as a thought leader, add value to your consumers’ lives and collect leads in the process.
There are a number of ways brands can use digital marketing to benefit their marketing efforts. The use of digital marketing in the digital era not only allows for brands to market their products and services, but also allows for online customer support through 24/7 services to make customers feel supported and valued. The use of social media interaction allows brands to receive both positive and negative feedback from their customers as well as determining what media platforms work well for them. As such, digital marketing has become an increased advantage for brands and businesses. It is now common for consumers to post feedback online through social media sources, blogs and websites on their experience with a product or brand. It has become increasingly popular for businesses to use and encourage these conversations through their social media channels to have direct contact with the customers and manage the feedback they receive appropriately.
But Google has championed machine learning as its future and seems 100 percent focused on growing this segment of the algorithm. Going forward, SEO practitioners will need to be proactive and invest in analyzing data and understanding search behavior across a variety of search and social platforms. This way they can develop the type of content that will motivate and influence user/search behavior which will in turn influence rankings and traffic.
