Google Search History Update

In my post You Are Being Tracked: E-mail Style there was some discussion/confusion about when I said:

Hopefully you know that Google keeps track of everything you have searched for.  Ever.

Well this it true and false depending on how you read it.  GHamilton noted that Google does not keep everything you searched for.  Rather they keep it for 18 months.  The key word here is “YOU”.  In a recent post on the Google Blog Google announced:

Today, we’re announcing a new logs retention policy: we’ll anonymize IP addresses on our server logs after 9 months. We’re significantly shortening our previous 18-month retention policy to address regulatory concerns and to take another step to improve privacy for our users.

You may see where I am going here.  GHamilton is correct in that from and individual IP perspective after 18-months, or rather 9 months now, Google no longer has history on you specifically.  I am correct in that Google really does have “a history of everything you have searched for.  Ever.” with the caveat that they no longer know that you were the one that searched for it after 9 months.  If you are interested CNET does a great job of getting into the nitty-gritty and explains why the ACLU is so critical of Google’s privacy policy.

Hopefully that helps clear things up a bit for people.  Let me know your thoughts.  Do you care that Google keeps your data for 9-months?  Should it be longer/shorter?  Should they keep anonymous search history forever?
