Facebook Groups come out best of the nine social media channels compared here, though few people talk about them. A Facebook Page post reaches about 1.25% of the Page's followers, according to Socialinsider's August 2026 data. No published study measures what share of a Facebook Group's members see a post in that group. A Facebook Group post takes less work to make than a post on any of the other eight channels. Facebook Group members are more likely to sign up than strangers who see a post in their feed. The cost of a Facebook Group is time spent every day answering, prompting and moderating its members, rather than hours spent making videos. The full comparison table puts all nine social media channels side by side.
No published study measures how many Facebook Group members see each post
- A Facebook Page post reaches about 1.25% of the Page's followers, and no published study gives the same figure for a Facebook Group.
- A Facebook Group post takes 5 to 30 minutes to make, because it is a discussion prompt, a poll or a quick tip with no video.
- Documented Facebook Groups have grown from zero to over 500 members in under three months.
- People who join a Facebook Group tend to stay members of that group.
- A Facebook Group post competes with the handful of other posts in that group this week, while a Facebook Reel competes with every other Reel on Facebook.
- Discussions in a Facebook Group keep drawing comments for days, longer than posts in any other Facebook format.
- Facebook Group members you talk with every day are more likely to sign up than strangers who see your post in their feed, though members still need a nudge to click a link out of the group.
Facebook itself recommends your Group to strangers, and that is where most members come from
- Facebook's own Suggested Groups feature recommends your Facebook Group to people who are not members. Meta, the company that owns Facebook, says one of its Suggested Groups systems predicts how likely a person is to comment in a group before suggesting that group to them.
- Facebook shows a busy Facebook Group discussion in the feeds of people who are not members of that group, labelled "Suggested for you".
- Facebook tells people when their friends are already members of your Group, and people join where their friends are.
- A new Facebook Group's first members come from people searching a topic and from members inviting friends.
- A public Facebook Group's posts are searchable on Facebook and Google, while a private group shows only its name and description.
A Facebook Group builds up reach while every Reel starts again from zero
- Every Reel or TikTok video is recommended on its own, so a video that did well last week does almost nothing for the views of your next video.
- Every new member of a Facebook Group is one more person who can see every future post in that group.
- A Facebook Group post will almost never get 500,000 views overnight the way one lucky Reel can, but a Facebook Group gives you a predictable few thousand people who see your next post.
- Running a Facebook Group means answering questions, prompting discussion and moderating every day, long before the group pays you back.
- A Facebook Group goes quiet within weeks of its owner stopping posting, and then Facebook stops recommending that quiet group to new people.
Use Repeat Recorder to rehearse a spoken Facebook Group post
The fastest thing to post in a Facebook Group every day is you answering one member's question out loud. Repeat Recorder, one of my own apps, records you, plays the recording straight back and starts recording again without you touching the phone.
- Repeat Recorder lets you rehearse the same thirty second answer five times without picking the phone up.
- A Facebook Group post takes 5 to 30 minutes to make, and rehearsing a spoken answer twice in Repeat Recorder still fits inside that time.
- Repeat Recorder recordings worth keeping go into favourites and into folders you name yourself, so a question that comes up again in your Facebook Group gets the answer you already worked out.
Conclusion: when a Facebook Group is worth growing
- A Facebook Page post reaches about 1.25% of the Page's followers, and no published study gives the same figure for a Facebook Group.
- Facebook's own Suggested Groups feature brings new members to your Facebook Group by recommending it to people likely to comment there.
- A Facebook Group post takes 5 to 30 minutes to make and needs no video.
- Start a Facebook Group only if you will post in it every day, because Facebook stops recommending a quiet group to new people.
