Earlier this week, Google's Matt Cutts ran down a bunch of new stuff Google's web spam team is working on. Cutts tweeted an extension of that today, noting that Google will continue to tackle link networks, and that in fact, they just took action on "several thousand linksellers" today.
In addition to http://t.co/ptV8oDZOwC it's safe to assume webspam will continue to tackle link networks that violate our guidelines as well.
In fact, we took action on several thousand linksellers in a paid-link-that-passes-PageRank network earlier today.
Let the good times roll.
Webmasters continue to anxiously await an upcoming, bigger version of the Penguin update, and Cutts also indicated that Panda would be easing up a bit.
As part of Cutts' big video, he said Google would continue to be vigilant when it comes to all types of link spam. Already, the webspam team is making good on its word.
