Experiments with AdSense
As an experiment, I've added some Google AdSense to the site. I'm not expecting much in terms of revenue, but you never know... Actually, this is more of an educational experience; I want to better understand the methods behind Google's madness. Maybe you do, too?
Having explored the system and learned a few interesting things, I've now removed the ads. My main conclusion is that Google does not have a lot of content my audience is interested in, or the targeting does not work well enough to find it. Even with a significant amount of traffic, click-through rates are just too low, and the ads I've seen are mostly off-topic. I suspect I could get somewhat better CTR with more prominent ad placement, but that's not something I'm willing to do at this point.
