To create a lookalike audience in FB ads do you have to have 100 sales from customers in 1 country? I’ve reached 100 sales (not all from US) but when I try to create an audience it says my sample size is too small. Anyone with any knowledge on this?

I used to export abandoned carts from Shopify and use that. I believe that option is no longer possible (or not as effective anymore).

You can create a custom audience based on the actions people took that were recorded on your pixel.

You’ll then create an LLA based on the original audience
