Can You Buy or Sell a PPC Campaign?

Has anyone bought or sold a PPC campaign? Now why would anyone ever want to do this? Because each campaign can be considered a "mini business" or asset.

And since no matter how hard you try... I don't think anyone can completely dominate a market for any particular keyword at all levels for every click that is available.

An example is a campaign I was doing while I was in the PPC arbitrage business. There was one campaign that I was doing that I know a few others were also doing. Some were making a couple thousands per day with this niche while I was only doing a few hundred per day.

I couldn't figure out how they were doing so much better but it really didn't matter to me as a couple hundred per day was great for me... but what if I could spin off multiple campaigns for the same thing by selling each campaign as a "mini business"?

Would it hurt my profits? I'm not sure... but if we already had 6-12 people doing the same "campaign" already and we all were making a decent amount of money then why couldn't it work?

By selling a campaign you would be selling a keyword list... a proven ad... and maybe the landing page itself if you had one if not direct linking.

Do you think this would work... and if so is anyone interested in selling any "mini ppc campaigns" that have been proven to be profitable?

Just an idea...
