The practice of getting a web page on a site you do not own or work on behalf of, to rank in Google for a particular keyword or phrase. The intent behind this could be humorous or malicious. Google bombers work by asking the internet community to link to a particular page on a website using prescriptive anchor text. Because Google’s algorithm takes into account anchor text from links to sites, if enough sites link using a particular word or phrase, the page / website will begin to rank for this term. Initially Google took the position that they would not alter any search engine results in order to preserve the integrity of their search engine. However, in September 2007, changes were made to the indexing structure in an attempt to defuse these bombs.
