Getting trouble scaling my facebook ads

I always start by testing my creatives (VideoAds, Carrousel, Images) with an engagement campaign on a budget of 10-15$/day for 3-4 days.
Then I choose the one who has the most likes, shares,.....
I create 4 LLAs (Add to LLA basket: 1%, 1% to 3%, 3% to 5% and 5% to 10%) and launch each of them in a conversion campaign with $10/day for 3-4 days.
I then usually get a few that are barely profitable and maybe one or two with a positive ROAS (>2-2.5).
The CPA is usually between $8 and $12.
The problem is that when I try to increase my budget (even safely with 10-20% for example), my CPA will eventually reach $20-25. So I have a huge loss of margin.
If anyone has any advice for me, that would be cool.

Note: I have 2.6k event add to cart in the last 3 months. Is that enough to create an LLA? Maybe that's the problem.

So basically, you have a CA from your engagement campaigns and then you are jumping into the conversion and target an audience which is outside of your engaging audience.
sounds like a misconception. The LLA has never engaged with your former marketing message, that’s probably why your prices getting up and have lower conversion

To answer your 2nd question: For a LLA you need minimum 1000 datapoint stock create aLLA, but again, 1st you should build a CA and retarget them before you think about creating a LLA

Thanks for your answer,

But how can you explain that I get a positive ROAS with a budget of $10/day, but I don't get one with 15-20-30$/day? The audience is the same, it has never engaged in either case, I'm just increasing the budget.

That’s strange, indeed. What conversion window you’ve choose? 1day, 7day?

It’s always hard to tell, without seeing the whole picture.

I tested the 4: click at 1 day, click at 7 days, click or view at 1 day, click at 7 days or view at 1 day. What worked best was click at 1 day but the difference was really small.

I don't use manual bidding as I heard it was mostly for a higher budget ($200+/day), do you think I should try it?

Yes, of course, here is a picture of my facebook ad report (not much to see but maybe there is something I missed).

In any case, thank you for your help !

Can’t see any of your metrics, all blurred

I would only consider a manual bid, under following circumstances:
Low cost CPM —>low cost CPC —-> above the average CTR
This scenario is mostly an indicator for a relevant offer without to many competitors

Thank you, I will test it out!

so if i were you here's what I would do.

1. Make the most of the money you;ve already spent. Which means, you've got 2.6k ATCs, now run a shit ton of Retargeting ads and sell to these people.

2. YES, you can use manual bidding. Use target cost strategy to control your costs on these ads and you should be good.

3. Go to the ad level and select all ads and click on "Create Rules". Here you can create automated rules that will control your ads even when you're not on your screen.

I usually have there setup.

(a). spent > 1.5 x target CPA & purchase < 1 = turn off.

(b). spent > 5 x target CPA & ROAS < 3.0 = turn off.

(c). Spent = target CPA & CTR < 2.0% = turn off

Hope this helps
