A week back Google addressed something I have wanted for ages; I want to sort Google search results by date. At the same time they have started something which is to get users to interact with the search space more.
This is not the first, a couple of months ago Google launched searchWiki which allows you to modify how your results are displayed.
This puts the searcher in the driving seat, and I am sure we will see more of this in the future, but what it means for SEO? Search results position becomes more subjective than before, and saying “my site has position #3 for xxyyzzz keyword becomes less relevant”.
