I am trying to get site targeted ads to appear but having no luck. I have cranked up the cpm to £5 but still no impressions. What sort of cpm have people had to use for different sites? I am bidding on a site with a few thousand hits/day I think.
Using this site (DP) as an example - I had to set the max bid at $10 and the actual CPM came in between $3 & $4. Keep in mind that it can take 24 - 72 hours for CPM campaigns to go live.
