What exactly is Google bombing?
Google bombing is a kind of search engine optimization trick performed on a website or name to associate it with a specific (often insulting or comical) search phrase. For instance, whoever was behind the more evil than Satan himself attack of 1999 must have hated Microsoft and wanted to make a statement against the company. With the right kind of manipulative search engine optimization, the attacker would have made Google associate the Microsoft website with any searches for the phrase more evil than Satan himself.
Over the years, people have used Google bombing to ridicule hundreds of people, both famous and unknown. Sometimes people skilled in search engine optimization manage to use Google bombing to settle personal grudges too. People attacked in this way may sue and win compensation.
