Not sure how new this is but it's the first time I've seen it. This morning when I logged into GoAn I got the following statement:
Press "Accept" to enable data sharing between Google Analytics and other Google services or for additional options, choose "More data sharing options".
If you click the More Options it gives you radio buttons where you can choose to Share Data with Google Products Only, Anonymously Share Data with Google Products and the Benchmarking Service (no clear definition of what the benchmarking service is or who runs it) or Do Not Share GoAn Data.
So the day has finally come when Google wants to start using the massive amounts of data they have via Google Analytics. It's nice they're at least giving everyone a heads up and a choice in the matter, but it does leave one to wonder if they're going to start using GoAn data as part of the SERP algorithm. That specific part isn't mentioned anywhere I saw, but it does leave one to wonder.
