Yeah I'll have to do this. I was avoiding it because I'm not that high of a roller and then I have to set a budget for each ad campaign.
I only spend $15 /day on PPC so if I create a separate campaign I can only allocate it like a $5 budget. ($10 search / $5 content)
The content network is click raping me though so maybe I'll just nix it.
You're splitting the two why???
Look dude, get some SERIOUSLY deep targeted sites on the content network and drop search.
Go to quantcast.com, use the media planner, and find 20 sites that are your ultra specific demographic, and have under 25K visitors a month, then see if they're running adsense. THEN, look at all 20, find the one you BEST think is gonna convert your offer. Do a CPM bid on that single site for $15/day (traffic / budget == bid). If you break even after 2 days, keep at it and adjust bid accordingly.
Start a new campaign, content only, CPM bids. Keep adding 1-2 sites per ad group. Customize the banners/text to that site. This is an extremely ghetto method, but your budget is so laughable you'll just waste money doing anything else.
Consider your time too man, how much time are you spending getting that $15 spent? Even at 100% ROI, you're losing money if you're working more than an hour per campaign.
$15 is absolute DICK to test an offer, and you're spending waaaay too much time on both networks.
Stick with targeting sites CPM until you start making some cash, it'll take for fucking ever to grow like this, but once you do, your ROI is gonna rock.
You'll also get a few more clicks this way, so you can optimize your lander faster, assuming you're preselling.
