I have two sites (two different domains, two different adsense channels, two totally different topics). What I sometimes see, is that adsense within a topic from site A shows up on site B. Right now, 3 out of the 5 advertisements in the adsense block on site B shows site A-related ads, which are totally unrelevant for site B.

Yes, I quite often have unrelated ads, but the topic for site A is so specific that I don't believe that advertisements for this topic could coincidentally show up on site B.

My only explanation is that the different adsense channels can infect each other.

there is evidence that adsense is also visitor-specific.

This means that if you visit sites about subject A (or if you do searches about subject A), Adsense remember you are interested in this subject, and might serve you ads about that subject even when you are on different sites.

As a "frequent visitor" to your site A, adsense thinks you are REALLY interested in that subject!

According to this theory, you should also see ads for subject A on other sites, not only your other site...

AdSense ads are indeed tied to the search phrase you used to find the page with AdSense ads on it.

I'm inclined to believe that to some degree. If there's a high paying keyword phrase that relates to Site_A that is even remotely semantically related to Site_B but not relevant to the particular subject matter of Site_B, those ads still seem to run, even though on Site_B they are totally worthless - to the publisher, to the advertiser, and to the visitor as well.

What I meant is that google can display ads about topic A on site of topic B, even if they are totally unrelated (both as the searched keyword, and semantically). This because the same visitor in its past visited or searched about topic A.

Thanks for all replies.

frox: I think I understand what you mean. In my case however, this is not what happened. The reason I can state that, is that I have rarely visited my site A lately, and until today it was probably more than one month since last time. Site A is totally static with no updates for more than one year. But still site A-specific advertisements showed up on site B earlier today, and at least one time earlier.
