The Google web search team launched a new Chrome extension to block low-quality sites from appearing in Google’s web search results. They explored different algorithms to detect content farms, which are sites with shallow or low-quality content. One of the signals we're exploring is explicit feedback from users.
Why this early release?
The Team launched an early, experimental Chrome extension so people can block sites from their web search results. If installed, the extension also sends blocked site information to Google, and they will study the resulting feedback and explore using it as a potential ranking signal for our search results.
How does it works?
When you block a site with the extension, you won’t see results from that domain again in your Google search results. You can always revoke a blocked site at the bottom of the search results, so it's easy to undo blocks.
You can also edit your list of blocked sites by clicking on the extension's icon in the top right of the Chrome window.
