Why isn't there an affiliate network that generates ads based on content of a page, much like Adsense? The great thing about Adsense and the like is that you just post a snippet of code and the rest takes care of itself, but with all the affiliates its all very time consuming because you have to find the right products and then enter the code on individual pages. I wish there was something that would generate banners or underline keywords in content and promote products that way.

I just want to focus on content creation and marketing, not spend time looking for products to sell, which one would think would be automated by now.

I know Amazon is good with this, but unfortunately for me my sites are types on which Amazon would not do well but rather affiliates like Markethealth, Valueclick would be better options.
