How to optimize your Instagram advertising campaign?

Question

Marketing

I have launched a RK on the Instagram of an online store according to the following logic:
One group of targetings that clearly express my target audience + a group of targetings (for example, by income level or level of education, etc.) + a group of MINUS targetings (something that does not apply to my target audience)
Audiences are divided into 2 age groups
24-34 and 35-45 years old
Question:
So I tested this AC, how can I now collect information about which specific targeting bundles are most effective?
My logic is something like this (but there are questions to this logic):
I look at the most effective ad groups
(How to evaluate their performance in the most qualitative way?)
Then I split these targetings into even more targetings to evaluate them separately
(But then I will have a much wider TA, and how then to evaluate this effectiveness of targeting separately?)
Then I collect the most effective individual targetings in a bundle (then I will have a different TA in general, and will it be more effective in such a bundle?)
OR
I can now collect effective targeting groups and combine them into one bundle (but then the target audience can turn out to be very narrow)

Answer 1

If you pour on insta - you have almost zero information about efficiency. You can only judge by indirect signs, for example, you can optimize to remove from targeting regions in which the cost of impression is high. Change the traffic flow scheme so that you can drive for conversions, and then there will be a lot of functionality for optimization.
