In March 2011, Google enabled a blocked sites feature, allowing users to block sites they do not want to see in the search results. That feature went away for some when Google introduced Search Plus Your World about 13 days ago.
This is a known issue, we reported it at Search Engine Land as part of the Search Plus Your World launch.
Those who have switched over to this new and more personalized search experience lose one big personalization factor, the ability to block results. Those who are still on on Search Plus Your World will still be able to benefit from the blocked results feature.
Here is how it works:
People are complaining about it at the Google Web Search Help forums - although there aren't a tremendous number of complaints.
On Friday, Albert from Google said:
Thanks for that update. I've brought up the issue, and we're actively working on a fix. I'll keep this thread updated as we can come up with a solution.
There is no ETA for a fix, but Google has been aware of it for 13 days and counting now.
