Wow looks like you giving ad space for free, for 40 thousands visitor you earning 0.61$ if you have only Asian traffic that could be the issues, no network has good rate or good advertiser for Asian traffic, especially cpm network does not pay anything for Asian traffic. I would suggest you optimizing your site with google adsense. There are some good network for cpm like valueclick, but again problem is same they also pay only for US traffic Other option you have is pop network and you will earn may be 10 time more then what you earning now and for Asian traffic as per my experience I find edomz is best option. If you looking for well established and trusted network than in cpm you have a lot of option, though earning wise it will be around same in all network, so you need first decide actually how you want earn more money from your website. I really doubt any good cpm network has good rate for Asian traffic unless they cheat and redirect visitors and all which is again not suggested.
Edomz has decent CPM rate for Asian traffic. If you traffic is legal, then try madads they are awesome but are pretty strict. But with 100% fillrate ( I estimate this more like 80%) they are worth getting into.
Very bad...$0.01 to $.02 eCPM rate is too bad. Remove the ads, try adversal first, then TechCPM, then CPMLeader.
Do you yourself has any experience in this you are recommending TechCPM recommending which has scammed already many check this thread for more details https://forums.digitalpoint.com/threads/techcpm-com-ad-network-cpm.2609001/
