Google Moves to Shuffle Down Low-Quality Sites

Google has made a significant change to its search engine that will push further down in its rankings websites that pilfer content from other places on the Internet or do not offer high-quality information, the company said in a blog post on Thursday.

The changes to its algorithms impact 11.8 percent of all queries, a significant change considering most people barely notice incremental changes the company makes. Initially, the change only applies to Google users in the U.S. but the company said it plans to roll it out further.

"We believe it's a big step in the right direction of helping people find ever higher quality in our results," wrote Amit Singhal, a Google Fellow, and Matt Cutts, a principal engineer. "We've been tackling these issues for more than a year, and working on this specific change for the past few months. And we're working on many more updates that we believe will substantially improve the quality of the pages in our results."

Many websites will cut portions of, for example, news articles with a small summary, which is usually cut directly from the story. The publisher of the site may offer little or no original content, but the sites can rise in the search rankings.
