i know this debate gets rehashed constantly, but after digging through every thread I'm still genuinely split. Running a $10 daily budget on a $100 product means I'm seeing maybe one purchase a week-hardly enough signal for the pixel to optimise on. The obvious move is to switch to ATC (add to cart) to give the system more data to work with, but there's that nagging fear that you're just training it to find window-shoppers who'll never convert.
Someone in the conversation argued that at this budget level you probably shouldn't even be running ads-fair point, but not exactly helpful when you need to test something. Another suggested testing ATC or even landing page views first just to feed the pixel enough events for stable optimisation. The catch they mentioned is spot-on: if your ATCs are full of low-intent clicks, Meta will happily go find more of them, and you'll waste budget on people who abandon carts for fun.
I suspect the real bottleneck here might not be the optimisation event at all-it's whether the creative and offer actually fit the audience. With a tiny budget you've got no room for guesswork. so I'm leaning toward testing ATC for a week, watching lead quality like a hawk, and if cart abandoners are garbage, pulling the plug and rethinking the whole funnel. anyone else tried this at similarly tiny scale?
