For myself this is the most interesting statement.
It’s worth noting that this update does not rely on the feedback we’ve received from the Personal Blocklist Chrome extension, which we launched last week. However, we did compare the Blocklist data we gathered with the sites identified by our algorithm, and we were very pleased that the preferences our users expressed by using the extension are well represented. If you take the top several dozen or so most-blocked domains from the Chrome extension, then this algorithmic change addresses 84% of them, which is strong independent confirmation of the user benefits.
Google has confirmed the value and accuracy of its Chrome blocker tool. The logical next step will be to include Chrome block data in the algorithm. Doing so will create a conveyor belt of sorts. As low quality sites are removed new sites will roll in. Any of these which are themselves low quality will become blocked by Chrome users. When enough people block a URL or site it too will be removed from the SERPs. A new site will enter the top rankings.
In this way Google can introduce constant filtering and, supposedly, improvement. If this is the Farmer Update then I predict the Kaizen Update is right around the corner.
