Aaron Wall broke the news on his site about Google’s new algorithm update. Supposedly, this update places heavy emphasis on a site’s “brand.” You can read more about Aaron’s take on this issue here.
There are a good number of people complaining about this algorithm update. Apparently some sites have lost their ranks to more noteworthy brands. This certainly could be the reason why so many webmasters think big name companies are getting preference in the serps over their more relevant websites.
To put some water on this fire, Matt Cutts has publicly acknowledged that a change was recently made to Google’s algorithm. According to Matt, this is not a major update but one of the 300-400 minor updates they make yearly. Matt also noted that the change would probably not even be noticed by the majority of webmasters.
