Just for your information, webmasters, COX still has not replied to my emails (I sent 4 in total). What happened is: my sold impressions went up last Monday (90% of my inventory got sold, up to that day only around 25% were sold which was very low so I was hoping more media will find my website and start adverting on it) So I was happy when on Monday my sold inventory went up to around 90%. The CPM rate was good and I made good money. Two days later the CPM rate dropped to around $0.20 - $0.30, which is under the minimum of $1 I have set. Even though I wrote many times to COX (Adify) no one has responded to give me explanation why is that! So the bottom line is they sell around 90% ads on my site for super cheep! If you ever consider using this company, please remember my story. I may not be the only one who experience this issue. I understand any error can occur in the system but how do you explain the fact no one answers my emails ? I guess you can make your own conclusion.
