As a part of offering more options to companies using AdWords, Google has publicly released a list of top 1000 sites on the web. The websites have been ranked based on several factors including unique visitors, pageviews and reach. Not surprisingly, Facebook tops the list with 540 Million unique visitors, followed by Yahoo!, Live and Wikipedia.
Google AdWords partners can now specify to restrict their ads on these 1000 sites only. This can be done by going to your AdWords account, going to the “category filters” section and then choosing “non ad planner 1000″ as the category. Doing this will only run your ads on these top 1000 sites and not on any other website unless specifically mentioned.
Clicking on any of the websites gives you a more detailed report on the traffic including average visits per visitor, average time spent on the site and top keywords used to search for the site. The report also includes a list of top sub-domains as well as a list of audience interests. However, the most interesting part of the report is the ability to drill down and see traffic details for each website at a country level. Simply pick a country from the drop down list and Google will show a detailed report on traffic coming from that specific country. The report was last generated in April 2010 and is supposed to be refreshed every month to reflect updated data.
