Test running promotional offer for HoneyToon comics 18+ on Facebook Ads, has anyone tried it yet?

[LeeK]

I’ve been testing the Honeytoon offer in the US geo for 2 months with a total spend of $700 but only made around $150 back. I’ve tried all three campaign types — Traffic, Lead Generation, and Conversion — but none of them seem to perform well. I’ve also installed pixel and API tracking through RedTrack, but I still can’t figure out why there are no sales.
Even so, I still don’t want to give up.
If anyone has run or is currently running this offer, could you share some experience?”
