Google Helps Webmasters Disavow Spammy Links

Google, to some, is a kind of god. So it's fitting that Google should offer redemption to those who have fallen from favor.

Google has just introduced what it calls its Disavow links tool, a way to disassociate one's website from linkspam.

In Google's book, linkspam is a sin. Linkspam, also known as Web spam or unnatural links, is a term to describe Web links that are deceptive or manipulative. Google sees a lot of linkspam because it treats links as votes for the relevancy of the designated website. Relevant websites appear at the top of search results lists and tend to get a lot of visitors; less relevant websites starve.

Many websites looking to improve their visibility in Google Search find it easier to pay some shady search engine optimization (SEO) firm to create a deluge of low-quality content that links back to the client's site than to craft copy so compelling that Internet users create links unbidden.

Google tries to discourage paid links, link exchanges, and other schemes designed to influence its relevancy rankings through its webmaster guidelines. But not everyone does the right thing.

Attempting to manipulate Google may pay off for a while, but sooner or later, Google is likely to catch on and the punishment can be severe. Several years ago, BMW was caught gaming Google's search system and Google reduced the PageRank of the offending website to zero, effectively excommunicating it for a time.

In a blog post, Jonathan Simon, webmaster trends analyst at Google, says that the Disavow tool is intended for website owners who have been notified of a manual spam action arising from "unnatural links" pointing at their site.

The first course of action he recommends is removing as many of the spammy links as possible. But because it's not always possible or practical to get in touch with the creators of incoming links, there's the Disavow tool. It tells Google to ignore incoming links that the website owner specifies in an uploaded file.

Google stresses that the Disavow tool is an advanced option that should be used with care. "If used incorrectly, this feature can potentially harm your site's performance in Google's search results," the company says on its website.
