Google has altered the algorithm on its search engine to push good quality websites up in the search rankings while punishing those that offer poor quality content or copy from other websites.
The company explained in an official blog post that the algorithm update impacts 11.8 percent of its queries.
The update, targeted at creating a 'healthy web ecosystem', will result in low search rankings for websites that provide poor quality content, are not very useful or copy content from others. At the same time, the update will promote better websites, with original content, higher up in the search results.
Google said that it wasn't using the data compiled from the Personal Blocklist Chrome extension on its Chrome web browser for this update, but they did compare the user generated list with the list of websites created by its algorithm. The comparison with the user blocklist suggested that the new update was very effective in its purpose.
“Google depends on the high-quality content created by wonderful websites around the world, and we do have a responsibility to encourage a healthy web ecosystem. Therefore, it is important for high-quality sites to be rewarded, and that’s exactly what this change does,” Matt Cutts, Principal Engineer at Google wrote on the blog.
