Google has added a wonderful new feature: the ability to block sites from your search results. You can read all about it on their blog post. Here is a snippet.
You’ve probably had the experience where you’ve clicked a result and it wasn’t quite what you were looking for. Many times you’ll head right back to Google. Perhaps the result just wasn’t quite right, but sometimes you may dislike the site in general, whether it’s offensive, pornographic or of generally low quality. For times like these, you’ll start seeing a new option to block particular domains from your future search results. Now when you click a result and then return to Google, you’ll find a new link next to “Cached” that reads “Block all example.com results.”As always, Matt’s been gracious enough to let us use him as an example. His site is awesome, though, and we doubt many people will want to block it!
But this does make me wonder. If you block a site, we can safely assume Google will track that. And if a site gets blocked too much will it drop in rankings where it hasn’t been blocked. I still believe this is a great tool and will be used by power users more than casual searchers, but it may have a more positive affect on overall search rankings than we realize. And that is probably a good thing.
