Today, Google announced that they will start to reduce the lifetime of users cookies up to 2 years. However, we should note that every time you visit Google, the cookie will be automatically be updated. The 2 years expiration will only be applicable if you’ll not revisit the site. So, just like what almost all bloggers said, this change doesn’t make sense.

I think it will be better if Google Engineers will consider the suggestion of Ryan Singel of Wired:

Now what would have been really cool is if the ultra-smart Google engineers — the ones who created Gmail and the very good PageRank search algorithm, separated preference cookies from logging cookies. That way Google could set the preference cookie for hundreds of years, but users could decide — based on how much trust they have in Google and the government — how long they would like Google to be able to log their search queries and/or internet browsing.

I wonder what will be the thoughts of Matt Cutts about it?

What is cookie?

By the way, I want to make it clear that we are not talking here about the cookies that can be bought at the grocery stores. The cookie we talked here is a computer file which is define as:

A small text file of information that certain Web sites attach to a user’s hard drive while the user is browsing the Web site. A Cookie can contain information such as user ID, user preferences, archive shopping cart information, etc. Cookies can contain Personally Identifiable Information (as defined below).
