Official Google Webmaster Central Blog: Page layout algorithm improvement.
Google is improving their page layout algorithm to better handle the content-supersaturated pages we end up finding all too often.
As stated in the writeup, the algorithm change affects less than 1% of searches globally, but that seems odd to me. I search quite a bit, and it feels like I’ve ended up on these types of pages more than 1% of the time. I realize, though, that I’m far from the majority and am glad a change is in the works!
If we continue to do our jobs by designing and building sites of high quality, this algorithm change should help us and our clients rise in the ranks.
