Google today released an early, experimental Chrome extension to help people block sites from their web search results. Once installed, the extension would sends blocked site information to Google, who in turn will study the resulting feedback and explore using it as a potential ranking signal for our search results.
You can start blocking sites now to help detecing content farms. 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. If you're a tech-savvy Chrome user, please download and try the Personal Blocklist extension.
