Long tail keywords are used when the website wants to refine search terms to the web page, as well as when the searcher is looking for something rather specific. Like normal keywords, long tail keywords are used to define what is on the web page and what the publisher wants to be found under in search engines and on search engine results pages. These keywords are highly specific, and draw less traffic for the website, but tend to draw more quality traffic, which leads in more conversions than normal keywords. Long tail keywords can also be used by publishers and visitors in different ways.
