> we've found this works better with sites that add value
I haven't. CPA tends to be the last resort of desperation for publishers -- unless, of course, the publisher's site is focused on the kinds of products advertised in the CPA network. Even still, realized CPM will be low.
We've had requests from both publishers and retailers for CPC / CPM pricing and our system is built to handle that, it's just a case of finding some time in the schedule to build and promote it!
Sorry Dom but I think unless you have CPC/CPM pricing you have no right of calling this Adsense replacement. 2-3 years back I would be applauding for launching something that could have potential to be an Adsense competitor but these days there are tons of ad-networks that monetize sites on CPM level quite well. I don't see how any publisher who has some experience in monetizing content would go for your CPA solution when there are CPM/CPC networks which user can make more money with.
