Best way to make the most revenue?

Hi I was wondering whats the best way to make the most revenue?

Should I sign up for more then one ad network rather then just one ad network and have the ads rotate? Or should i take a different approach?

And also is there an free ad server that will rotate the ad if one network does not have an available ad to display OR if one ad network can not display to a certain country then the program will automatically check for one the will?

Please let me know thanks!

 

for me best revenue is sell link and review

 

Yes you should try different kind of ads network to search for the one that really give you the max earning.
You can use this ads rotators such as this http://blog.taragana.com/index.php/...otate-your-ads-including-adsense-dynamically/

 

ah ok, so rotating ads between networks will give the most revnue correct? instead of always displaying just one network at a certain part of the site?

also does this software you mentioned display ads from another network when one ad network can not display an ad or when one ad network can not display an ad for the specific country?

let me know thanks for the info so far!
