In September 2000 the first Google bomb with a verifiable creator was created by Hugedisk Men's Magazine, a now-defunct online humor magazine, when it linked the text "dumb motherfucker" to a site selling George W. Bush

Adam Mathes is credited with coining the term "Google bombing" when he mentioned it in an article that appeared on April 6, 2001 in the online magazine uber.nu. In the article Mathes details his connection of the search term "talentless hack" to the website of his friend Andy Pressman by recruiting fellow webloggers to link to his friend's page with the desired term.

Uses as tactical media

The Google Bomb has been used for tactical media
Tactical media
Tactical media is a term coined in 1997, to de note a form of media activism that privileges temporary, hit-and-run interventions in the media sphere over the creation of permanent and alternative media outlets. Tactical media describes interventionist media art practices that engage and critique...

 as a way of performing a 'hit-and-run' media attack on popular topics. Such attacks include Anthony Cox's attack in 2003. He created a parody of the "404 – page not found" browser error message in response to the war in Iraq. The page looked like the error page but was titled "These Weapons of Mass Destruction cannot be displayed." This website could be found as one of the top hits on Google after the start of the war in Iraq.

Alternative meanings

The Google Bomb is often misunderstood by those in the media and publishing industry who do not retain technical knowledge of Google's ranking factors. For example, Alex Jones creates "Google Bombs" every week by dispatching instructions to his radio/internet listeners. In this context the term is used to describe a rapid and massive influx of keyword searches for a particular phrase. The keyword surge gives the illusion that the related content has suddenly become popular, however it is artificial in nature because it is created by a loyal following of people to a particular media outlet, often alternative media. The strategy behind this type of Google Bombing is to attract attention from the larger mainstream media and influence them to publish content related to the keyword.

Google bowling

By studying what types of ranking manipulations a search engine is punishing, a company can provoke a search engine into lowering the ranking of a competitor's website. This practice, known as Google bowling, is often done by purchasing Google bombing services (or other SEO

 techniques) not for one's own website, but rather for the website of the competitor. The attacker provokes the search company into punishing the "offending" competitor by displaying their page further down in the search results. For victims of Google bowling, it may be difficult to appeal the ranking decrease because Google avoids explaining penalties, preferring not to "educate" real offenders. However if the situation is clear-cut, Google could lift the penalty after submitting a request for reconsideration.
