Tool to search for Facebook groups in particular niches.

Do you guys still use Facebook groups to connect with your audience? Despite young people not being as into Facebook anymore, I still think their group features are super useful for business. I'm a software developer, and I actually found three of my past job opportunities through Facebook groups.

Anyway, recently I built a product with my friends, and we realized that there are potentially thousands of Facebook groups that we could utilize for our marketing efforts.

But finding the right group for our niche proved to be a bit of a challenge. So, I quickly put together a tool that searches for groups in our niche and ranks them by engagement (no of members, likes, shares, comments, etc).

It's only semi-automated for now, but it's been a huge help so far. I'm thinking lots of features could be added. Wondering if you guys know of any similar tools?

I'm sharing the data sample for top search results for "entreprenuers" keywords, rank by number of members and user engagement.

Public groups with feed analyze (Top 100 search results) - https://drive.google.com/file/d/1jwYGHyby-OUrIKieigYMriHi-MUVb4V3

Private groups (Top 500 search results) - https://drive.google.com/file/d/1VaEhiAkRJg2ODIhdRux7GdyyHmOCyV0-

If you want some data sample for your keyword, let me know in the comment section. I'll analyze and get you top 30 groups from first 100 search results.
