I reported at the Search Engine Roundtable that some searchers are noticing that Google is asking them to suggest search results that will “help improve search for everyone,” says the Google message.
The review URL submission, takes you to a login page, which then takes you to a form that looks like this:
Next time you do a search on that phrase, your suggested result will be shown with a red asterisk. Google also says:
After you submit the URL, it takes you to http://www.google.com/reviews/w/nominate, which is a 404 page for me. It does, however, appear that Google has many /review pages indexed.
So this feature seems like a way to nominate and review nominated search results in Google. Maybe a community like social search feature added on top of Google personalized search.
