Can your Publishers run their own direct sale?

Absolutely! Premium sales (direct sales as well as ad network cooperation) still generate the most money for the publishers. This will change in the future (and is already changing in some markets) but for the time being we recommend our Publishers keep their premium sales. Yieldbird handles programmatic only, we don’t run against publishers’ premium sales.

Do you monetize only desktop? What about mobile & apps?

We have developed our service to keep up with demand and having originally started with desktop optimization, we now offer mobile optimization. Our app optimization capability will be available soon. This is currently in testing phase but watch this space!
