Google filter away low quality search resuts

Following the release of a Google Chrome extension Personal Blocklist to facilitate blocking of sites from your search results and send the information back to Google so Google can eventually use submitted results to filter away low quality domains, thus improving search results, Google announced in a blog post that algorithm towards search rankings is updated.

This update is designed to reduce rankings for low-quality sites—sites which are low-value add for users, copy content from other websites or sites that are just not very useful. At the same time, it will provide better rankings for high-quality sites—sites with original content and information such as research, in-depth reports, thoughtful analysis and so on.
