Google released a list of the top 1,000 most visited sites on the internet based on unique visitors, as measured by Ad Planner. The list will be updated monthly as new Ad Planner datasets are released.

Interesting to note that Google.com is not listed at all – they state the following: “Keep in mind that the list excludes adult sites, ad networks, domains that don’t have publicly visible content or don’t load properly, and certain Google sites.”
