I have a site which has around 4 million visitors per month, website based on movie review with free links offering. Require CPM/CPC mix banner ads (NO POPUPs/UNDERS).
Come to Clicksor.net. I can help optimize your site. http://client.clicksor.net/member/auth/signup?role=publisher&admin_id=60031
Clicksor is unfortunately a tainted name. Your ads had a buttload of malware and redirects in them at one stage.
LOL, AdBlade didn't reject you because of that Alexa rank. They have plenty of pages in the 100K-200K area. So there's more to this story than that.
I have some experience with Adblade. I have found them to be pretty reliable, when their plugin effectively disabled adblock, I received some very impressive eCPM's. Now, adblock is 100% effective against my adblade and my CPM can be seen. I personally prefer to keep adblade despite being offered some higher CPM's purely because I know their ads are 100% safe, compared to other companies which have trouble with malware. It gives me one less ad placement to monitor for malware. There are higher CPM's out there for larger websites, but I think Adblade is ideal for smaller publishers.
@NoTally is dead on. AdBlade is effective, 100% safe, and gives 100% fill. The one thing I will say is to make sure that you look at numbers on AdBlade on a monthly basis as opposed to day to day. I've seen <$1CPM days on ads and seen the same ad pump out a week of >$5CPM. It really does just depend on what they have running. It seems like their optimization is fairly good - it's uncommon for me to see ads that have zero relevance to my users. The other content reco networks that offer higher CPMs do so at the cost of "spammier" ads that just look terrible. For instance, when we ran one of those networks, there was an ad with a picture of a meth addict looking old lady that kept popping up and we were directly receiving complaints about that ad - never a good sign. Never had that problem with AdBlade, but you do have to realize there are CPM swings because of a lot of factors.
