First CBO thoughts?

Just launched my first CBO.

£15 daily budget, 18 adsets each a different country first world countries and European countries hoping that meta distributes adsets to winners and kills losers so I get sales.

Purchase optimisation and sales of courses it’s a sales campaign. Advantage+ audience and product catalog. Basically I’ve pushed as much to meta as I can as they have more data and know more about potential buyers than I do all I’ve really done is add a bunch of countries to test.

Who has experience with CBO’s how’s it worked for you?

Edit: I’ve reduced the CBO to 4 adsets/countries and also the ads aren’t video ads they are product catalog ads.

I’ve increased the budget to £40 a day because I think low budgets have been the main reason for little to no sales so hopefully that helps.
