More Google search algorithm changes announced from Google today. This time its about finding more high-quality sites from search results as the search engine war vs content farms continues. They also mention what roll the Google Chrome Personal Blocklist Chrome extension played in making changes to the search algorithm. Here’s an excerpt from Google’s official blog.
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.
So, we’re very excited about this new ranking improvement because we believe it’s a big step in the right direction of helping people find ever higher quality in our results. We’ve been tackling these issues for more than a year, and working on this specific change for the past few months. And we’re working on many more updates that we believe will substantially improve the quality of the pages in our results.
