How to analyze a Facebook group's activity, members and top posts

Facebook's own Group Insights are admin-only and cover just recent activity. If you want to understand any group you belong to, who carries the conversations, which posts people actually engage with, and what the community keeps talking about, you can build that analysis from the group's own posts and comments. Here is how, and what each number tells you.

Step by step

  1. Download the group with comments. Open the group with Group Exporter for Facebook installed and click "Download this group" with "Comments & replies" on, so the activity counts include who comments, not only who posts.
  2. Open Insights. In the dashboard, open Insights and pick the group.
  3. Read the rankings. See the most active posters and commenters, the most-discussed posts, the words that come up most, and activity over time.
  4. Export to dig deeper. Export posts.csv and comments.csv to rank members your own way in Excel or Google Sheets, or JSONL to let ChatGPT or Claude summarise what people discuss.
Try it on your group, free. The free version downloads 200 posts with all their comments. Pro is $24.90 once for unlimited.

Who is most active

Two rankings matter, and they are rarely the same people. Top posters start the most discussions; top commenters answer the most. The commenters are often a group's most valuable members, the ones who help newcomers, and the obvious candidates when you look for moderators or partners.

Because every comment carries its author and date, you can also count answers per person over any period, or spot members who have gone quiet.

Which posts people actually engage with

The most-discussed posts, ranked by comment count, usually hold the group's best knowledge: the questions everyone had and the answers that followed. Reactions and shares show reach, but comments show real engagement, so sort by comments to find the threads worth turning into a pinned post or a FAQ.

What the community keeps talking about

The most-used words, with everyday filler words removed, surface the topics and questions that come up again and again. Click a word to find every post about it. Over months, it is a cheap way to see what members really need, which feeds a FAQ, a piece of content or a product idea.

Activity over time

Posts and comments per month show whether the group is growing, steady or slowing, and reveal seasonal peaks. For community managers it is a quick read on the group's health; for researchers it dates a trend.

Crunch the numbers yourself

The Insights view is a fast overview. For anything custom, export posts.csv and comments.csv and build pivot tables (comments per author, engagement rate per post, posts per weekday), or export JSONL or Markdown and ask an AI assistant to summarise sentiment or the most-recommended answers across thousands of comments.

Everything is computed on your computer from data you can already see as a member; nothing about the group is uploaded anywhere.

Free vs Pro

Insights work in the free version on the up-to-200 posts it downloads from one group. Pro ($24.90 once) analyses the whole group history, across unlimited groups, and keeps it current with daily updates.
