If you want users to click on ads you basically need to fool the users into clicking or show actually relevant add. Because actually relevant adds are almost non-existant, fooling becomes the main strategy. And the best strategy is to make adds be indistinguishable from content. And I do not refer to short-sighted way of incorporating ad links into the content, so the user thinks it is useful, because after he clicks he knows he is fooled. I refer to ad blogging, or "promotional" blogging, where people write articles that are sometimes quite thickly-veiled adds, puts a bunch of banners around it and make people read it. Then people think that they are avoiding adds by not looking at banners often not even realizing that the "content" is an ad of itself.
