Backlinks (also known as “inbound links”, “incoming links” or “one way links”) are links from one website to a page on another website. Google and other major search engines consider backlinks “votes” for a specific page. Pages with a high number of backlinks tend to have high organic search engine rankings.
Bounce rate (sometimes confused with exit rate) is a term used in web site traffic analysis. It essentially represents the percentage of initial visitors to a site who “bounce” away to a different site or back to a search engine query results page, rather than continue on to other pages within the same site.
Google’s AdSense monetization platform for website publishers has continued to grow. As a result, a new business model appeared: “built for AdSense”.
Thousands of websites that were built specifically to satisfy search engine algorithms and rank high in the search engine results pages. Some of these were called “content farms” (see eHow) while others were simply called “built for AdSense” websites.
In both cases, the main goal of the publisher was to generate revenue through the display of advertising through providers like Google AdSense, rather than be a comprehensive resource on the given topic.
Critics claim that these sites produce marginal content, not of benefit to users, but good enough for search engines to rank.
