Three Essential Keyword Research Tools

A keyword is a word or phrase that a web user types into the web browser in order to search for a topic that she is interested in finding information about. The web search engines take this word or phrase and searches its indexed catalogue and returns to the web browser those items (websites) that contain relevant content to the user. There are sophisticated algorithms behind the search that eliminate junk but that’s basically it – a search engine carries out a rapid search through an indexed database.
