I rarely use Google for search these days. I switched to Bing a few months back when others here at WebmasterWorld decided to "kick the habit." On Tuesday, I found out that a person I once knew was working for a company I hadn't heard of. I did a search on Bing using my IE toolbar to search for the company name.
Bing listed the company first in the SERPs, of course, and I clicked the link and visited the site. The site was a corporate site, and had no advertising on it whatsoever.
I looked at a couple of pages, then left.
Later on Tuesday night, I was at another site totally unrelated to my site or the company site I had visited earlier. Wasn't I surprised to see an AdSense ad advertising that company!
Now, today, I've seen ads for that company appearing on MY site as well.
How in the heck does AdSense know I searched for this company? I used Bing to search, and that site didn't have advertising on it. I do not have the Google toolbar installed on this computer.
