Meta Ads strategy Q&A, need experienced advertisers.

I have some questions for people who actually have experience with MetaAds.

1 - Is it more logical to stick with multiple ad sets or just 1-2 ad sets? (Some advertisers stick with only 1 ad set, adding creatives and increasing the budget.)

2 - Do you stick with an A+ target audience or do you go by breaking down data (placements, age, etc.)? In other words, do you take control from MetaAds as data comes in?

3 - Do you use target audiences or go with Broad?

4 - Do you test with a very low budget and then increase it, or do you allocate a high budget and not touch the set for a week?

5 - MetaAds breaks all metrics after a certain point (usually 3-4 days), CPC increases, CTR decreases, and conversions stop. How should one act in these situations? Some say be patient for a few days, others say close and open a new one. What should be done?

**6 - I'm testing 5 video creatives, 3 ad sets (adset 1 > broad A+, adset 2 > audience A+, adset 3 > audience A-) with a product profit/budget of 3. I'll test the most successful creatives with a larger target audience, duplicate the successful ones, and scale with CBO after 50 orders. What would your opinion be on this strategy?

Thanks in advance.
