On 24th Feb again Google announced the improvements taken place in the Google search results -
Many of the changes we make are so subtle that very few people notice them. But in the last day or so we launched a pretty big algorithmic improvement to our ranking—a change that noticeably impacts 11.8% of our queries—and we wanted to let people know what’s going on. 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.
Google have compared the Blocklist data gathered through the Personal Blocklist Chrome Extension to make the necessary changes. For now, we can see changes in Google U.S. search results only but will be rolled out soon everywhere. It is sure to see some ups and downs in the rankings if you have website targeted U.S. market.
We can see, G has clear intentions to stop Search Spam and only high-quality sites (websites with original content and information) will rank on the page 1.
