They could even go as far as using that users profile and search history to try to determine the stage of the buying process they are at.
I recently wrote an email through my gmail account where I was talking about floor lamps. Then I went back to general browsing, and immediately on a number of sites (news, etc) I was suddenly seeing ads for light bulbs, designer lighting, lampshades, and more along those lines.

That was my profile that evening, and that my friends is laser beam marketing at the cutting edge of online commerce.
