Having a search engine also being the one who provides the ads makes for interesting reading.
Check the bottom right of your blog and you'll see the google ads. But here's the kicker - the google ads are based on Google's search engine results. So you can see what kinds of people are visiting your site, to a degree, based on what types of things are being advertised.
I was reading Tangled Wishes website and the ads were about personal relationships, meeting people, that sort of thing. I read through my blogs and I see a bunch of ads from right wing sites. I guess that should tell me something. But now I know where I can get a "liberal vooodoo doll."
Reading through Wahkonta's site and I see ads for UFO sighting books and news.
The google ads are far more interesting than I ever thought they'd be.
