New Chrome extension: block sites from Google’s web search results

News from Google

(Cross-posted on the Google Chrome Blog)We’ve been exploring 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. To that end, today we’re launching 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 we will study the resulting feedback and explore using it as a potential ranking signal for our search results.


You can download the extension and start blocking sites now. It looks like this:


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.

This is an early test, but the extension is available in English, French, German, Italian, Portuguese, Russian, Spanish and Turkish. We hope this extension improves your search experience, and thanks in advance for participating in this experiment. If you’re a tech-savvy Chrome user, please download and try the Personal Blocklist extension today.
