Official Google Webmaster Central Blog: A quick word about Googlebombs

Co-written with Ryan Moulton and Kendra Carattini

We wanted to give a quick update about "Googlebombs." By improving our analysis of the link structure of the web, Google has begun minimizing the impact of many Googlebombs. Now we will typically return commentary, discussions, and articles about the Googlebombs instead. The actual scale of this change is pretty small (there are under a hundred well-known Googlebombs), but if you'd like to get more details about this topic, read on.

First off, let's back up and give some background. Unless you read all about search engines all day, you might wonder "What is a Googlebomb?" Technically, a "Googlebomb" (sometimes called a "linkbomb" since they're not specific to Google) refers to a prank where people attempt to cause someone else's site to rank for an obscure or meaningless query. Googlebombs very rarely happen for common queries, because the lack of any relevant results for that phrase is part of why a Googlebomb can work. One of the earliest Googlebombs was for the phrase "talentless hack," for example.

People have asked about how we feel about Googlebombs, and we have talked about them in the past. Because these pranks are normally for phrases that are well off the beaten path, they haven't been a very high priority for us. But over time, we've seen more people assume that they are Google's opinion, or that Google has hand-coded the results for these Googlebombed queries. That's not true, and it seemed like it was worth trying to correct that misperception. So a few of us who work here got together and came up with an algorithm that minimizes the impact of many Googlebombs.
