Frequently asked questions.

What's ads.txt?
A file publishers post to list who may sell their ad spots. We read it for every listing.
What's sellers.json?
An exchange's list of the companies it pays. It confirms who's really selling.
Why does direct matter?
Buying through the publisher's own account usually means fewer middlemen and fewer fees.
