Hey Maxine1974,
A bit of advice - before you start a thread saying that a certain CPA Network is crap, you might want to be careful. Maxbounty AM's are on this board and if you ever wanted to get approved to run a special offer or need help....you might not get the best treatment. I'm sure they would still help you, but maybe not as much.
I would suggest using another CPA network and running the same offer. If you get 20 conversions with neverblue, and 2 with Maxbounty, then you have a legitimate beef.
The fact that you are not getting conversions could depend on your promotion method. I have tons of offers that "Never" convert and some that have 75% conversion rates. Most of the time it's me and my promotion and not the network.
I would suggest testing out another network for sure, That's the easy thing to do. Then if it doesn't convert, start tweaking your landing page and promotion methods. Also don't be afraid to move on. This is a fail quick business. If something is failing keep it moving.
I hope that advice helps.
Good Luck!
