@Incredibill still not convinced that they do take into consideration of all the data you mention. I agree that they monitor the web, but doubt they have the capability (as yet) to incorporate all this into the ranking algorithms in terms of computational power. IMHO that is..
They are debatable points for sure but here's a serious rational for why Incredibill is likely more right than wrong.
When logged into a Google account you get tracking data as [NOT PROVIDED] for your markets.
Google suggested that was to protect user's privacy when using Google... but the query is in fact associated with your domain (not solely Google's domain) so the user automatically desire you to be included in their privacy clause (otherwise they wouldn't click out of Google.
What it does prevents however, is you having the exact same data Google has access to which limits your ability to reverse engineer intelligence about your markets. That data is proprietary and now exclusive owned by Google.
