Just because you've logged out of a site doesn't necessarily mean the cookies have been deleted. Google can still track you just as effectively until you've cleared your cookies. In fact, if they store IP address and useragent information, they could continue tracking you even afterwards.
Now, I don't know that they do that, but they certainly have the technical means to do so.
- dereferenced2 15y agoPretty sure they do. Watch this ted talk about filter bubbling from last year: http://www.thefilterbubble.com/ted-talk http://www.thefilterbubble.com/ted-talk He mentions they use ~30 points of info to identify you, even if you're logged out.
- tonfa 15y agoFrom the talk: > Even if you're logged out, one engineer told me, there are 57 signals that Google looks at -- everything from what kind of computer you're on to what kind of browser you're using to where you're located -- that it uses to personally tailor your query results. He says they are signals used during ranking, not something to identify people.
