Access Google’s data about your Website
The official Adsense blog has a pointer informing us that the Google Sitemaps service has a handy extra feature that lets webmasters view statistics on their websites from Google’s perspective.
By just creating a Sitemaps account and uploading an empty HTML file to verify you own the website, Google provides statistics about the Pagerank distribution across all of your pages, the top queries to Google that return pages to your site as results, and the top queries that actually directed traffic your way.
In addition, you can check exactly what errors (if any) the Googlebot encountered while crawling your site.
As an extra convenience, they also throw in a handy “Index stats” section that lets you run advanced queries on your site like the link:, site: and allinurl: commands.
