Fighting spam to keep your results safe and useful is a daily challenge.
While we want to be really transparent about how Search works, we also have to be careful not to reveal too much detail that would allow people to game our search results and degrade the experience for everyone.
We learned this lesson the hard way. Back in 1999, Google’s founders published a seminal paper on PageRank, a key innovation in Google’s algorithm. Once that paper was published, spammers tried to game Google by paying each other for links.
Search is a powerful tool. It helps people find, share, and access an amazing wealth of content regardless of how they connect or where they are located. We work hard to ensure that you see high quality Search results and not spam. We’re continuously improving our spam-fighting technology and will continue working closely with webmasters and others to foster and support a high-quality web ecosystem.
