Working with direct advertisers is another level altogether compared to advertising networks. When you work directly, you have more control: you choose what you want to advertise, and you discuss the terms without any unnecessary intermediaries. Revenues, by the way, are also usually higher, because no one takes their commission. Yes, it can be more difficult to negotiate with advertisers, but it's worth it. I, for example, found TOP Affiliate Network, and the income was twice as much as with networks. If you have the opportunity, it's definitely worth a try.
