I presume that the content on your website is somewhat NSFW, otherwise you would be using Google Adsense or media.net to server the adverts. They give full reports, pay well, and in my experience pay higher for mobile browsers.
You say that they send you a cheque, with no breakdown of figures. This seems almost unbelievable to me.
not NSFW at all! Actually our advertisers are as Top100 as they come!
Adsense was not really performing that well when we made the switch, but even after the switch to the new provider - we haven't experienced the highs we were hoping for.
But yes, the company who manages our inventory is quite respected in the industry we are in - simply horrible with their reporting for our figures.
And yes, no breakdown of figures. I guess this is the wake up call i needed to either start receiving reporting, or sever our relationship.
It's an agency. They have actual sales people who have relationships with the companies and sell them ad campaigns on individual sites (in a certain niche).
Because I have an exclusive agreement with that agency.
It's obvious now after reading some of these answers that i need to review my agreement with them
