24.02.2011 Google has introduced further changes in its algorithm, this time changes are to be more pronounced than usual.

What does this mean for the SEO?

This set of changes in SEO may affect approximately 11.8% of the search queries and will apply to the main part of the content published online. The purpose of the algorithm refresh is to eliminate the network of sites with low quality content that is not valuable enough to users and often have copied contents from other sites and online sources.

This change will mean that the Internet users will benefit from valuable, unique, informative and insightful content.

This change does not result only from taking into account the comments and suggestions arising from the users of popular Chrome plug-in :Personal Blocklist (which, incidentally, was also put into operation last week).

Unfortunately, the new Google algorithm will be present initially in the U.S., and then will be extended to other countries..
