How Many Company to work With Is Too Much

Okay whats my best bet for a site, im working with clicksor, adbrite and mediashaker.. so basically im running ads from all three on my sites is that too much and do people do more im just asking casue i dont know whats the best way to monetize the site, and is it okay to have an ad from all 3 of em on like the same page?

 

Are u only trying cpm companies why not try some pay per click companies like bidvertiser

 

because my click thru rate are pathethic i have something like 100,000 impression per like 3 clicks and its not being dramtic.
