As a business its important for us to have a source of revenue. Currently with the exception of the four plugins we take 5% from and a couple of legacy plugins that have been around for years, we have backend revenue deals with our partners. The amount of each deal may vary between plugin partners and us, and it’s a fee they are paying us to have you as customers.
At the end of the day, the only thing that should matter to you is your eCPM for comparing each of the providers to decide which ones work best for you. Companies generally do not discuss partner details with the public and we are not going to either.
