Facebook Interest Targeting research [Facebook Ads]

Hii BHWs. Today I am here with the most common but most Insane question "How to Research Facebook Interest for Facebook Ads", In Simple Words, we all know about Facebook Interest base targeting but many times we don't know how to find out the best & high relevant Interest in it.
Anyone can suggest me any checklist, any tool or want to share any like so it helps me in Facebook Interest targeting research

Thank you

Can you explain the term "Geo Grouping"

start to do wide on wide

Any reasonable explanation?

You should start with a few niche that you believe your audience will come from and also you can start a campaign to go wide (all age group that loves iPhones or all age groups that loves netflix) and then once you start getting some conversions, you can then build custom audience from the conversions. This requires that you have the facebook pixel installed. Once you have the custom audience with some conversions, you can build look-a-like audience. Look-a-like audience can be build for Purchase, add-to-cart, views, leads, etc. So you can try all of them and scale.

This had worked for me for many products. I was able to scale it big with just the look-a-like and let FB do its work.

There is a tool called https://www.facebook.com/business/insights/tools/audience-insights

no caso o publ personalizado pode ser criado depois das primeiras conversões ou pode criar anttes?
