Hello everyone! I want to have some CPM ads on my website, but the best offer I have is .37$ CPM. That's my average on 200k impressions so far. However, today I noticed one website which claims to have $4 CPM and I was reading more about CPM then I realized that the average is $3-4 (is it true?). If it's like that, could you please suggest me a good network? I get ~60% traffic from the USA and ~10% from other "top tier" countries combined. Others are from the rest of the world. Website niche: Sports (NBA). Thanks!
