Hello!

I am about to set up a site, which consists of completely dynamically generated content. There is nothing to spider or take a look at ahead of time. No fixed URLs or any such thing. It's a bit weird that way, but that's how it is.

I would like to display contextually relevant ads on those pages. Now, I know what the page is all about as I am creating it on the fly. In fact, I even know what the user was looking at beforehand, what the user is normally interested in, and so on. That's all great. However, where do I get the ads from? Most ad-networks will rely on the fact that they can pre-spider your site and know what it is all about. But that is not possible in this case.

Is there a decent ad-network, which allows me to specify the speciifc keywords and/or topics, which it should consider to select ads? I can easily on the fly adapt the HTML code that one usually needs to include to get ads from someonebody's ad-server. So, I can insert those keywords/topics right there as the data is returned to the browser.

I would be interested in text ads as well as graphical ads. If anyone can recommend an ad-network to me, which gives me the flexibility to determine and specify the context of an ad-selection, that would be great.

Thank you very much!

Tom
