Google stated on their blog today that they have indexed 1 trillion unique websites. Unique meaning they have not counted sites that are auto-generated copies of other websites.


Google also notes that they do not index sites that have duplicate content. An important fact to Web masters and businesses who rely on Web traffic and seo. The reason appears to be multi-facted. Reasons such as removing spam sites and cutting costs seem to be the main reasons for de-indexing duplicate websites.
