Notice the various values, including GG Score, Adv, Vertical, and PVs. As soon as I saw this, when Philipp Lenssen blogged about it, I dismissed this tool as an AdWords tool. Heck, why would Google organic assign these values to the organic results. I thought, this is a nice tool to find potential AdWords customers. How much is this potential customer worth (GG Score)? Do they already advertise in AdWords (ADV)? What vertical would we place them in (Vertical)? How many PageViews can we generate for this site's advertisement (PVs)?
Later, Matt Cutts, of Google, confirmed that this is not a Google organic tool:
Our organic search results have always been completely independent from our paid advertisements. We consider the objectivity of our search results to be paramount to our success and would never compromise that in any way.
The screenshot shows a tool that is not used by the search quality team in any way. It is a tool used by members of our AdWords sales team to help prioritize new customer acquisition. We are strongly committed to maintaining the integrity of our organic search results.
