GoogleI would wager that Web and SEO professionals have almost certainly made a massive dent in the nation’s supplies of both Red Bull and hard alcohol over the past few days. It reminds me a bit of last April, when Google rolled out its Penguin update, and websites all over the Internet saw huge chunks of traffic vaporize.

This time, it’s the new disavow tool, designed to take the sting out of low-quality inbound links and introduced with a warning to use it sparingly, if at all.

Google Disavow is a tool website administrators can use to remove “spammy links” to a site. Having a lot of “spammy links” to a site — from sites such as link farms, porn sites, or paid link campaigns — actually lowers your rankings at Google. You can’t prevent other sites from linking to you, however, and some sites do not respond to takedown requests. Google Disavow lets site administrators upload a list of links they want removed from their link profile. If Google thinks the request is genuine, it will “reconsider” the site’s Google rank, leaving out the spammy links.

Here is a complete 10-minute rundown by Google’s Matt Cutts:

Cutts even says in his video that they are well aware of the fact that some people will just dive in and start killing links left, right, and center. The thing I find interesting is that due to the timing, we can almost certainly identify one group of people that will probably do so: the political class.

I wrote last week about Mitt Romney accidentally Google bombing himself. Do you really think someone on his team is not seriously looking at this as a tool for mitigating the damage? Likewise, with Obama’s Web team, I’m sure there is a huge number of inbound links they would love to consign to oblivion. Even knowing that it might take weeks before there is any visible impact will be little impediment, I am sure.
