In the last few hours I noticed something strange with the AdSense ads that appear on this site. While before most ads were about blogging and RSS, recently I’ve seen a bunch of ads that seem to be triggered by keywords like “speed reading”, “memory improvement”, “online surveys”, “IQ testing” and stuff like that. The point is: I never used those keywords here (now I have, so I have just probably perturbed the phenomenon by talking about it, in a sort of feedback loop).
I had the suspect those ads were paying more per click than the previous ones, but the first results don’t seem to confirm my suspicion. My sample, however, is still very small, so it might just be that nobody is clicking those ads yet (and please don’t, unless you’re really interested in the products advertised).
I’ve experiences similar issues, except I’m getting ads for dating on a tech blog. Maybe Google knows more about my audience than I do? I’d expect ads related to tech products and services would be more relevant to readers.
We also have adsence on our website which is a technical site about data loggers and marine data collection systems. More than once we have noticed some strange ads appearing.
