Optimizing for Website Conversions... delivery stopped

Hey guys,

This has been annoying me and I'm wondering if anyone has any suggestions. I've setup 12 campaigns split by desktop/mobile and into various age groups (25-29, 30,34, 35-39, etc). All of my ads are high in relevance score (9 or 10) and my uCTR for most of these ads is between 4% - 7%. They are connected to a page so not all of these clicks are actually hitting the website and facebook is just counting general engagement like comments, likes, etc as clicks.

So, I've set Facebook to optimize for website conversions (customers buys something).

The first day the campaign ran I got 15 conversions with a 110% ROI. The following day, 2 conversions (10% ROI), then everything just trickled to a halt pretty much. Spending looked like:

Day 1: $154.80 15 conversions (all but 4 campaigns had at least 1 conversion)
Day 2: $31.12 2 conversions (only 2 campaigns had a conversion)
Day 3: $10.71 0 conversions
Day 4: $8.92 0 conversions
Day 5: $8.23 0 conversions

I'm thinking this is happening because there aren't enough conversions for Facebook to optimize with. Anyone have any other thoughts?

I wish I could figure out what they're doing to "optimize" because I ran CPC for a week with the same campaigns / targeting and was only able to pull about 6 conversions while losing about $300 in the process. Anyone have any theories on what Facebook does behind the scenes to further optimize your targeting?

How would you guys break this down to further isolate the winning angle?

We need more info. What was your bid? What is your CPA? How big is your audience? What is your CTR? Etc.

Audiences vary from 70,000 to 750k (depending on age group). I just set pricing to "Get the most website conversions at the best price" and it started out great, then just dropped off. CTR is anywhere from 4-7%.

you likely just need to be bidding higher to force some impressions. FB won't start properly optimizing for conversions until you are hit ~25/day.
