What's wrong with Adsense? Irrelevant ads?

Hi everybody

I'm experiencing some very strange behavior on my site which is using Adsense. Normally that ads are pretty relevant, since my site mainly discusses one specific topic. Last weekend I noticed that my Adsense had dropped 50%. When I further investigated this loss, I discovered a very strange thing: when I browse to my site using the url:


The ads that are displayed are irrelevant (ads about blogging, calendars etc). When I browse to my site by adding a slash (/) to the url, I get once again very relevant ads.


Anyone knows an explanation for this?

Indeed, looks like the same problem. When did your problem start?

Still, problems with slashes or with the exclusion or inclusing of "www." may be canonical in nature, that Google has indexed the same page on your site more than once with the minor URL differences. We used to have a bunch of pages that came up with different page ranks depending on whether or not the "www." was included in the URL, and they seemed to incur a duplicate content penalty in some instances. Google fixed all of these about a month ago, at least for us, but it's worth checking your page ranks. If Google has different PR for the versions, and if they are using PR in a quality algo for ads, it would all make sense.
