I have noticed this too universetoday. I think it is a good move if we can get more generic site wide ads for a few minutes and then more targetted a few after that.
I think google tries to theme a site, so it can target ads approximatively based on the estimated site theme. It might also look at keywords in the url. I have had ads on an internal test site behind a firewall, and google has never seen a page from that site, and it still served reasonable ads based on keywords from the url.
So overall site theme seems to influence ad targetting, and so does the individual words in the url.
Yes I get the same ads as my index page for new pages... It could be a coincidence though and just site themed ads as you said...

I've certainly noticed the former. Quite a lot of my quite narrow-subject pages are showing similar ads to my home page.
I've used quite lengthy file names to get keywords in, but I haven't noticed this having much affect on the subject matter of the ads.

I deduced so based on having adsense ads on a server that was behind a firewall. The referring url will be just about the only information google has to work with.
However they do it, I am pleased. As someone who has many new pages added daily, when AdSense stopped targeted ads on new pages over a period of 4 or so days at the end of July / early August, those charity ads were definitely noticed as was the missing revenue.
They are using the URL for sure. I'm going to have to rename my Discus message boards I'm afraid. I keep getting ads for discus fish. The only place that word appears is in the url to the message boards.
I can understand from your post that there isn't much of a market for discus fish supplies :-) I would probably have click out of curiousity, but probably also only once.
I've noticed that certain domains seem to be getting smarter...perhaps that's due to this 'theme-ing'...sounds like a good idea.
They definitely are using the domain...in fact, when doing new sites, I usually put it though this tool....
you can put any domain name in there, even before your site is up, and see what ads will be served just based on the name. I've changed some names accordingly.
I've got a tool similar to this sitting on my hard drive behind a firewall.
Yes, I can confirm that AdSense looks for keywords in the URL/folder/filename
I've got nothing to do with golf. But when I put "mydomain.com/golf/" into the tool, golfing ads were served up.
However, as I said earlier in this thread, I think that AdSense looks only at the file names when its got nothing else to go on. Certainly my long and descriptive file names on one of my sites don't seem to improve the targeting.
I have a page that mentions Santa Clara, CA. I kept getting Santa Clause Costume ads. I just put those advertisers on my block list and started getting relevant ads. Very cool.
