Google says they’ve managed to neutralize the impact of a lot of Googlebombs.
A Googlebomb is a when a group of people get together to link to a certain site with a certain set of keywords, in order to convince Google that it ought to display that site at the top of search results when queried for these keywords. (This often worked because Google does a lot of backlinks analysis when they determine their search rankings – the words you search for need not be on the page itself which ranks well for it.) In the past, for example, people tried to connect George W. Bush’s official biography page with the word “failure”... and a counter-bomb tried to connect Michael Moore’s homepage with the same query. The impact of this trick can be increased by telling people who don’t know how Google works to “enter failure and hit the I’m Feeling Lucky button!”
Now Google always claimed that the impact of these Googlebombs wasn’t big in relation to all searches performed on Google; Google’s Marissa Mayer said Googlebombs are “distracting to some” without affecting “the overall quality of our search service,” and Matt Cutts agrees that tackling bomb phrases wasn’t high priority as they were “well off the beaten path.” But the truth is that the bombs still received major spotlighting within recurring blog and mainstream publications over the past years – and a lot of people misunderstood the Googlebombs, thinking it was Google who was delivering their opinions... a typical killing the messenger problem.
