Stupid question....how do you define a campaign? From what I've read, most people said they failed on 10 - 15 campaigns before finding their first successful one.
Is a campaign 1 ad, lander, and offer combo?
Is a campaign 1 angle, consisting of several ads, landers, and offers?
Or, is something completely different?
Just one of those things that I've never got a straight answer to...hopefully you can help.
That depends of how people use it, but to me a campaign is an angle ( so ads + offer + lp ) on a traffic source.
Moving it on a new traffic source would count as a different campaign.
Rad. Now it's time to start my midgets with one arm, no teeth, and salt&pepper hair dating campaign. Wish me luck! 
Thanks for asking this question, I was wondering the same thing!
