For anonymous user the only way is the cookie.

You place an encrypted ID to the cookie and connect that id with your anonymous user on the database.

Google set up advertising cookies to last for 30 days for example

http://www.google.com/privacy/ads/

Google analytic set up up to 2 years

http://code.google.com/apis/analytics/docs/concepts/gaConceptsCookies.html

Google Analytics sets an expiration date of 2 years for unique visitor tracking. However, if your visitors delete their cookies and revisit your site, then Google Analytics will set new cookies (including new unique visitor cookies) for those visitors. While you can configure the duration of a user session cookie (from the default 30 minutes) using the _setSessionCookieTimeout() method, you cannot configure the duration of the unique visitor cookie

Thanks. I was thinking same way . But I thought is there a better way to do this.
