Google bombing as defined by Answers.com: “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.”
In the largest ever case discovered of its kind, when a search is done on Google for the word “failure”, the result — George Bush’s Whitehouse Biography.
So it wasn’t just “miserable failure” that resulted in the number one rank for the current President much earlier. With 78.3 million results in Google for that word, it was no small feat to get this specific page ranked for that word.
All bloggers did was to place the URL for that site into the anchor text in their copy. The search engine spiders pick it up and used it to rank a page.
Following my discussion on anchor text you can begin to see that your site’s anchor text is one of the most important weighted factors to get ranked for your keywords.
Choose your anchor text wisely and well using research not guesswork.
