Those stats are over 1 week, but I had my daily budget low - $30 to $50 but never more then $50/day for this campaign.
I was more or less getting a feel for this particular dating offer and your right $100 profit in a week isn't worth the headache but I find once you gather a bit of data and know which is your top performing ads are then its easy to increase your daily budget to get the traffic and start increasing those daily profits.
Basically when I'm doing this (On offers I don't have a lot of data on) I'll set a low daily budget, let it go for a good week to slowly gather the data I need, once I have that data, I stop all my split-testing, create a new campaign with only the highest converting ads (Usually the ones which also have a decent CTR) and then increase the daily budget and continue to do a/b testing on those top converting ads.
If you've got the money to spend, dating offers on Facebook can easily generate a 150 - 200% ROI.
I'm not sure what ROI is acceptable for you but I'm happy with ranges above 100%.
But just to be clear if I get a 100% ROI on $100 that means I made $200 - $100 of that profit, I know some people calculate ROI differently by saying a 100% ROI is breaking even - Had that discussion lots with peeps in the past haha.
Oh ok, I didn't know that you had a low budget on the campaigns, I thought that the impressions were simply maxing out on their own. I usually split-test 20-30 campaigns at a $100/day budget per campaign, wait till I have at least 250 clicks for each campaign, and then optimize on my best one. It's sloppy, but less time consuming for me personally.
Yea, know what you mean, since really it can stand for:
Return On Investment
or
Return Of Investment.
