Google has released a detailed, 49-page report that rates the SEO on its different properties adding the Google search home page.

On the clear side, the company says it plans to use this information to better its own SEO, and that to help others, the company has shared some of the metrics it's used.
The report covers 100 of Google's products. The company is also planning a follow-up that will cover international localizations.

Another low point of the report is the company's score on the destination sites where images of logos led. These are the Google product logos that have a propensity to reside in the upper left hand corner of the screen.
