A few days ago, AOL released a massive amount of search data of their users. I was able to download a copy for myself but now, somebody created a web interface and our fellow CW blogger from networkingforpros.com also blogged about it .

Anybody now, can search this database by going into aolsearchdatabase.com

In an SEO point of view, this is a very very good document to find out more about what keyphrases people use to search and the best of all is that you can follow the search phrases used by a specific user. Just click on the userid and you'll see what searches he/she has done.
