Who is adsenses biggest competition?

I would like to test YPN if they ever accept international members... So I think they can be competition if they want...

 

can we use YPN,Chitika or any other adsense like system with Adsense?? is it forbidden??

 

YPN and MSN.

 

if you search google for "competitors" it turns up with no results

 

What about widgetbucks?

 

they are too new, no one been paid yet.... so thats not competition YET.

 

no competitor is really bad, for the publisher.

i think the more competitor, the more benefit for the consumer in this case publisher and advertiser

 

I think no competitor yet YPn I think wont succed with non american users

 

From my perspective, no other programs competes with Adsense right now. A few come close... but Adsense is in a league of their own for now...
