Options to grow facebook group

I think there's a form of "SEO" for FB groups, it's based on activity, keywords in the title/description and member engagement. Groups that post daily, have high comment rates and use relevant keywords in their names tend to get suggested more. It's not random, but it's less predictable than Google SEO.

In my opinion, Facebook groups don't rely on traditional SEO; their growth depends on the active participation of their members. Group ranking is based on: high post engagement and activity levels, strategic keywords, and member interaction frequency.

Facebook has its own internal SEO system
