On a Google search yesterday I spotted something I had never seen before which is further evidence of the increasing personalisation of search results. On a search result for the AdWords help centre Google told me how many times I had visited the page and when I last visited (see screenshot). At the time I was signed in to my Google homepage and so it would be linked to my session I am sure but it is a further indication we are on our way to a fully personalised SERP. It will be interesting to see if they begin to use this as a CTR metric as with the PPC model and use it to rank the results in the same way.
