This is kinda amusing to me because my buddy Peter and I were just talking this morning about how it was inevitable that Google would have to weigh in on the comment spam plague. Today they announced on their blog that they will be implementing an “nofollow” tag that will allow you to block links on your site from being used for ranking purposes on Google. The same rule applies to MSN and Yahoo searches. From the blog post:
If you’re a blogger (or a blog reader), you’re painfully familiar with people who try to raise their own websites’ search engine rankings by submitting linked blog comments like “Visit my discount pharmaceuticals site.” This is called comment spam, we don’t like it either, and we’ve been testing a new tag that blocks it. From now on, when Google sees the attribute (rel=”nofollow”) on hyperlinks, those links won’t get any credit when we rank websites in our search results. This isn’t a negative vote for the site where the comment was posted; it’s just a way to make sure that spammers get no benefit from abusing public areas like blog comments, trackbacks, and referrer lists.

All I can say is thank goodness. Maybe it’ll at least slightly reduce the 300+ comment spams this site gets a day, although to keep beating a dead horse, the great product Spam Karma has been blocking them all. I’m also glad to see that my blogging engine, WordPress is already on the case.
