I posted an entry a little while back about how Google keeps track of your searches and personalizes your search results based on what you search on and the pages you click on.
Well, it now appears Google has stepped it up a level and will now personalize your results whether or not you’re logged in. This is something that will have an impact in particular on many SEOs. However, if you do good marketing (and not just the technical side of it), this shouldn’t change things too much. Check out this CNET article for the bulk of the info.
For those of you who don’t want Google to track you, you do have a few options. One is an opt-out option inside of Google that you can go in and activate, the other is to use some kind of plug-in to deactivate cookies. My personal favorite is the Web Developer plug-in by Chris Pederick. But it’s not the end of the world – you still do have options.
