In my experience, I can say that working with direct advertisers is much more profitable than working with advertising networks. Firstly, the income is more stable and higher, because there are no middlemen who take a part of it for themselves. Second, you have more control over what ads you get on your site. I realized all these facts when I started working with TOP Affiliate Network. This is important, especially if you want to keep your audience. Yes, it’s more difficult to negotiate directly, but when everything is set up, the result is better. I checked this out for myself, and now I prefer to work only in this way.
