Multiple Campaigns With The Same Offer?

I have a succesful campaign running in the content network. My question is: If I start a second campaign with the same offer will it too have similar success? Can this double my profits or will I just compete with myself?

How can I grow this into more revenue?

 

Don't duplicate the campaign in another account. Instead search for more profitable keywords. But remember, there is a point where you've covered all the bases and adding more keywords won't help much because you've found the good ones already. (slim chance but it exists.)

 

You'd just compete with yourself, and end up paying more for pretty much the same amount of traffic.
