Google Bombing
A Google bomb or Google wash is an attempt to influence the ranking of a given site in results returned by the Google search engine. Due to the way that Google's PageRank algorithm works, a website will be ranked higher if the sites that link to that page all use consistent anchor text. Googlebomb is used both as a verb and a noun.
For example, if a user registers many domains and all of them link to a main site with the text "... is a living legend" then searching for "living legend" on Google will return the main site higher in the ranking, even if the phrase "living legend" doesn't appear on the main site. A common means of exploiting this is through weblogs, where although the entry may disappear from the main page quickly, the short-term effects of a link can dramatically affect the ranking of a given site. Empirical results indicate that it does not take a large number of websites to achieve a Googlebomb. The effect has been achieved with only a handful of dedicated weblogs.
