can you compile a list of CPC networks that DO NOT require a minimum volume of pageviews to qualify?
I will update the list soon, the list above is part of my ad research project, but right now busy with expanding own ad network/exchange, hopefully, it will take a rank on the list as well. About the networks: even CPM networks require clicks, your CTR affects your CPM rate, some ad networks (e.g. LockerDome) can provide fixed CPM. If the ad network doesn't require a volume of page views, it will require a minimum amount of ad impressions. If you could share some info about the site stats, I could probably suggest something more specific.
Do visitors return to your site or most of the visitor's one-time visit?
What is the average time on site and how many page views per visit?
You should consider adding monumetric too I have heard great things about it
Monumetric is not an ad network, they provide ad management/mediation services and take % of your revenue.
The list above is the ad networks and it's based on the ads.txt records.
In addition to ad networks, that simply provide you with ads to monetize your visitors, there are also companies that do not have own demand, but they provide demand from other ad networks and ad exchanges. These companies manage an ad server and do yield optimization, while you just check your dashboard. Usually, they take % of your revenue. There are also companies that provide management services (ad operations) for a fixed monthly fee and you keep all the revenue. The difference between fixed management fee & mediation companies is that you own the ad server, and all the management is done on your accounts. I work with the latter and not very familiar with Monumetric.
