Hi, Google bomb :- The combined effort of multiple webmasters to change the Google search results usually for humorous effect. The “miserable failure†– George Bush, and “greatest living American†– Steven Colbert Google bombs are famous examples
To make a site to rank for other keywords than is natural to appear. For example,if you make a site about "dogs" to rank for "seo services" or a site of a friend to rank for words "the most stupid man on the planet".
It does not work any longer unless the anchor text actually appears somewhere on the target page. If your competitor uses the word 'worst' on his page you could link to his site with 'worst' in anchor and it will then rank for 'worst realtor' or whatever his business is. :=)
It's when lots of people create thousands of links to one page to try to get that page to rank for whatever the anchor text of the links was. Ex: People link to George Bush's page with the anchor text "idiot". A few hours later, when you search "idiot" on Google, George Bush's page ranks first; just because of all the links.
definition - A Google bomb is an attempt to bias a search result on Google by increasing a Web page's PageRank algorithm not only considers keywords when determining PageRank, it also considers the number of other sites that link to a page and the words used in the link description. A successful Google bomb requires that a high number of Web sites link to a specific Web page using specific words in the hyperlink. Enlisting high-traffic sites is especially important when creating a Google bomb, as their outgoing hyperlinks weigh more in Google's search algorithm.
