Assume you're looking for web/mobile web app? I have a similar issue with being declined by Adsense for a non-content (app type) site. I'm not earning huge amounts, but over the last 3 months I've been using the following display networks, all are CPM based (not CPC) and not content/contextual driven: - Amazon CPM. Pretty good, guaranteed CPM, with an average but consistent fill rate. Mostly remarketing of Amazon basket/viewing with a few good quality advertisers as well. They don't have great payment terms though (2 months+), limited ad sizes and limited payment options (I'm based in UK, and they offer USD check by mail payments only). - Sovrn (mobile/desktop). Been great so far, but haven't been through a payment cycle yet. - Facebook Audience Network (mobile only). Very variable fill rate and CPM. Ads are generally for mobile app install. - Adversal (mobile/desktop). Not great quality ads and low CPM, but 100% fill so only use as remnant ads. I only use these networks for 300x250 on desktop/tablets and 320x50 mobile banners at the moment, but Sovrn and Facebook also offer Native ads, which I might change over to in the near future (higher CPM than banners). All of the above except Adversal support passbacks, so you can waterfall ads to help with the low fill rates. I use DFP for Small Business to handle this, but it could easily be setup manually after testing each network. Others: - Airpush (mobile web). I used to get pretty good CPM for mobile web ads, but stopped using them as was getting some very poor/nefarious ads (click hijacking and malware). They may have sorted out the issues now. - BuySellAds. Need to do a bit more work to improve my sites ad placements, so haven't used them yet. I believe it's a bit more hands on than an ad network, but would look at these.
