The 30% is where your offer goes. How to place it in groups that allow it, in a format admins keep, is covered in how to advertise in Facebook groups.
What the 70/30 rule really means
The 70/30 rule is a ratio, not a schedule. It says: for every promotional thing you do in a Facebook group, you should be doing at least twice as much that’s genuinely useful to the members. Some marketers state it as 80/20; the exact split matters less than the principle — you earn the right to promote by contributing first.
It’s measured per community, over time — not as a daily quota. A group where you answer questions every week and drop a relevant offer once a month is well inside the rule. A brand-new member whose very first post is a sales pitch has broken it, whatever the math says.
Why people get reported
There are two separate forces working against pure self-promotion, and the 70/30 rule addresses both:
- Admins and members report you. Groups exist to help their members. When someone shows up only to sell, admins remove the post and often the person — and members hit “report” because it feels like spam. Enough reports and Facebook restricts the account.
- Facebook throttles promotional posts. Independent of admins, Facebook’s ranking reduces the reach of posts that look like ads or carry external links in the body. So even a promo that survives the admins often reaches very few people.
Value-first activity fixes both: it builds recognition (so admins and members trust you) and it earns engagement (so Facebook shows your posts to more people).
| Behavior | How admins see it | How Facebook ranks it |
|---|---|---|
| Only promotional posts | Spam — removed / banned | Low reach, link penalty |
| Value first, occasional promo | Trusted contributor | Higher reach on the value posts |
| Identical promo copy-pasted everywhere | Obvious spam | Duplicate-content signal |
| Genuine help + promo where allowed | Welcome member | Normal-to-high reach |
How to deliver the 70% (value)
Value doesn’t have to be time-consuming. Pick a couple of these and do them consistently:
- Answer questions in your niche. Being the person who reliably gives a useful answer is the fastest way to build recognition.
- Share a short tip or mini-guide with no link and no pitch — just something the group can use.
- Comment thoughtfully on other people’s posts. Engagement is contribution too.
- Ask a good question that starts a discussion. Question-led posts earn comments, which lifts your standing and your reach.
For more on the formats that earn engagement, see Facebook group engagement tactics.
How to do the 30% (promotion)
When you do promote, do it in a way that respects the community:
- Lead with the value, not the link. Frame the post around a result or a problem you solve, and keep it conversational.
- Put the link in the first comment, not the post body. Groups routinely delete link posts on sight, and Facebook reduces the reach of posts with external links. Dropping the link as the first comment keeps the post clean. See how first-comment links work.
- Follow each group’s rules exactly — some require a specific format, a flair, or a promo day.
- Never paste the identical promo into many groups. Vary the wording (and the image) so it doesn’t read as a bot broadcast.
Where promotion is actually allowed
The 70/30 rule assumes you’re promoting in the right places. Some groups welcome promotion; most learning and community groups don’t. Look for:
- Buy/sell and marketplace groups — promotion is the point.
- “Promote your business” / “shameless self-promotion” groups — built for it.
- Promo days — many communities run a weekly thread (e.g. “Self-Promo Saturday”) where links are welcome.
Everywhere else, treat your presence as reputation-building: contribute, get known, and only mention what you do when it’s genuinely relevant to a question. A practical habit is to keep a separate list of the groups that actually allow promotion, so your offers only go where they’re welcome — the Facebook group marketing strategy playbook goes deeper on organizing this.
What counts as promotion, and what admins actually remove, varies from group to group; Facebook group promotion rules explains how to read them before you post.
Applying the rule across many groups
If you’re active in dozens of groups, the 70/30 rule still holds — you just apply it deliberately:
- Keep a bundle of only the promo-friendly groups and send offers there, while you build reputation manually in the communities that matter most.
- When you do post a promotion across many groups at once, vary it so each group gets a slightly different version rather than an identical copy. Varying the text (with Spintax) and rotating between different images keeps the posts from looking mass-produced. See bulk posting without getting restricted for the safety mechanics.
- Space the posts out rather than firing them all in the same minute, and keep the volume reasonable per day.
This is where MultiGroupPoster fits: it posts to the groups you’re a member of from your own browser session, puts your link in the first comment automatically, varies each post with Spintax and rotating image sets, and paces posts with randomized delays (its Natural Presence setting on Balanced) so a batch looks human rather than robotic. It’s the “how” for the 30% — it doesn’t replace the 70%.
Common mistakes
- Joining and immediately pitching. Contribute for a while before you promote.
- Ignoring the rules. The fastest way to get removed is to break a rule that’s pinned at the top of the group.
- Links in the post body. Move them to the first comment.
- Copy-pasting the same promo everywhere. It reads as spam to both admins and Facebook.
- Treating every group as a promo channel. Most groups are for reputation; only some are for selling.
FAQ
What is the 70/30 rule on Facebook?
The 70/30 rule (sometimes stated as 80/20) means at least about 70% of your activity in a group should be genuine value — answering questions, sharing tips, joining conversations — and at most about 30% should be promotion. It keeps admins and members from flagging you as a spammer.
How do I promote in Facebook groups without getting reported?
Give value first so people recognize you, only promote where the group’s rules allow it (promo days, buy/sell and ‘promote your business’ groups), follow each group’s posting rules, put links in the first comment instead of the post body, and vary your posts so they don’t look copy-pasted.
Why do Facebook groups delete promotional posts?
Most groups exist to help members, not to host ads, so admins remove obvious self-promotion to protect that experience. Facebook also reduces the reach of posts that look promotional or carry external links, so pure promo tends to underperform even when it isn’t deleted.
Where is it actually OK to promote in a Facebook group?
In groups whose rules explicitly allow it: buy/sell groups, ‘promote your business’ or ‘shameless self-promotion’ groups, and on designated promo days that many communities run weekly. Always read the pinned rules before posting.
Does posting to many groups at once break the 70/30 rule?
Not by itself — the rule is about the ratio of value to promotion within each community, not the number of groups. You can post a promotion across many promo-friendly groups at once, as long as you’re also contributing value in the communities where you want long-term standing.
Follow the 70/30 rule and promotion stops being a game of dodging bans — it becomes a byproduct of being a useful member. Give value, promote where it’s welcome, keep your links in the first comment, and vary what you post.
