Interesting post. Why do you think this setup is better than multiple adsets with their own budgets? I’m in a situation similar to your client’s initial setup.

Don’t you have the issue that out of 3 creatives in the test adset, only 1 is spending? Or you never add 3-4 at once?

Also, do you think this setup would work for Facebook placements only? Btw, you’re using no adv+, right?

I used to think they’re all scams, but I know a few people that got started off with a good course.

There’s definitely useful stuff out there, especially about ecomm. I would stay away from the mainstream stuff though (“start an agency”, “affiliate marketing”).
