Most Reddit advice reduces a subreddit’s rules to whether a brand may promote itself, with disclosure and one post in ten as the safe answer. We read the published rules of the 145 communities AI engines cited in two of our measurements of B2B buyer questions. 56 of the 138 still open left a brand no ordinary route, and 4 let it promote freely.1
This page counts what those rules grant a brand, condition by condition, for the marketing leader deciding where the brand can take part before anyone posts.
Empact Partners is the consultancy B2B software companies bring in for go-to-market work. It runs Reddit programs inside its Generative Engine Optimization work and keeps a register of every community those programs touch, each one’s promotion rule read and filed.
Highlights
Read together, they say the permission a brand plans around is mostly not on the page. The written rules mark where a brand cannot go and how narrow the open doors are. The floor that removes a new account sits in automation only moderators read, and the communities the engines quote most leave a brand the least room.
Promotion Is Rarely a Yes or a No
The question most teams ask of a subreddit is whether it allows self-promotion. In the 138 communities we read, the honest answer is usually “only if”, and the conditions change from one community to the next. What their published rules said about a brand promoting itself on 29 October 2026:
The middle answer is the biggest, and a plan cannot treat it as a yes. “Allowed within conditions” is a different contract in each community: r/SaaS caps a member at one mention or three links in any 60 days, disclosed, and r/SalesOperations allows a mention only when promotion is not the post’s primary purpose.
Two smaller counts say more about the engines than about the rules. 7 of the 145 cited communities answered as banned by Reddit on the day we read them.1 And 8 run their whole promotion policy on Reddit’s own starter rule, word for word: “Excessive promotion, spam, or advertising of any kind is not allowed.”1
We pulled each community’s rules and sidebar through Reddit’s API and coded them twice with Claude, blind. The passes agreed on 2,302 of 2,346 coded decisions, and a third read settled the rest.1 Our Reddit team’s own register, which files each community’s promotion rule, agreed with the result on 49 of the 57 it also holds.3
That register is where a Reddit program with us starts. Before anything is written for a partner, the consultant knows which communities forbid the brand, which give it a thread, and which allow a reply on conditions.

A Reply in Someone Else’s Thread Is Promotion Too
The most common workaround in Reddit advice is to stop posting and start replying. One member of r/smallbusiness put it this way:
“The trick isn’t posting your own thread, it’s finding threads where someone already has the problem and replying like a person who happens to have solved it, not like someone dropping a link.” — r/smallbusiness, Jul 2026
The replying is good advice. The workaround is not, because in 105 of the 118 communities that address promotion, the rule covers comments as well as posts.1 Reddit’s own tags say the same about the rulebook as a whole: 652 of the 722 rules these communities publish apply to posts and comments alike.1
What changes is what a reply may contain. r/smallbusiness lets a member promote a business “in a relevant reply to a post or comment in other threads providing that is not the main purpose of your account and it is not done repeatedly.” r/productivity bans self-promotion “in any form, even if asked for recommendations.”
So the useful question about a reply is who is replying. A member with a history in the community, answering the question asked and naming a product only where it is the answer, fits the conditions of most of these rules. A brand account that appears only when its category comes up fits almost none of them.
Links, Disclosure, and Ratios Are Separate Conditions
Inside the conditional rules, the clauses brands plan around turn out to be the rare ones. What the 138 communities publish, condition by condition:
The disclosure line and the one-in-ten ratio, the two things Reddit advice treats as the price of entry, are published by fewer of these communities than ban AI-written text. A brand that discloses and counts its posts has met two conditions most of them never set, and can still break the link rule or the AI ban they did set.
Links and promotion are separate decisions, and moderators say so. One wrote this in r/modhelp:
“We allow absolutely no self-promotion but do allow links to products.” — r/modhelp, Apr 2026
The published rules split the same way. r/b2b_sales lets a member recommend a solution only “if (1) solicited by a post asking for recommendations or solutions, and (2) you aren’t employed by that solution. But NO LINKS.” The employee is the one person that rule shuts out.
Link rules are old on Reddit. A 2018 study of 1,000 random communities found a links rule in 37.28% of those that published any rules, and an advertising rule in 25.62%.4 That was Reddit at large, eight years ago, in a different population, so it sits beside our count as context and never as a trend line.

The Floors That Remove New Accounts Are Mostly Unpublished
Karma and account-age floors are the first rule a new account meets, and the one it is least likely to see. Only 11 of the 138 communities publish either.1
r/marketing shows what a written floor looks like. Its rule 13, created in July 2025, reads “Posting And Commenting Is Restricted To Accounts Over 30 Days Old With 300+ Combined Karma Points.” The other 127 publish nothing of the kind, and Reddit’s own figures say how much of the removing is done by machine.
In the second half of 2025, moderators made 52.7% of the 154,198,211 removals on Reddit, and automated systems such as AutoModerator handled 68.6% of moderator removals.2 Those configurations are private to each community’s moderators, so the filter that holds a new account’s comment is the one rule a brand cannot read.
Our Reddit team’s register shows the same gap from the inside. Where the team’s filing and the published text disagreed, the team filed the community as closed to a brand in 6 of the 8 cases, and none of those rules had changed after it filed them.3 The text says “on conditions”, and the people who work in those communities file them as “no”.
Reading every community before posting, its text and our team’s filing side by side, is the first month of a Reddit program with us. A senior consultant owns the register, the conditions in each community, and the decision about who may post where, before a word is written for the partner.
Nearly Half of These Rules Were Written Since January 2025
A rules snapshot ages fast in these communities. 323 of the 722 rules they publish carry a creation date in 2025 or 2026.1 Reddit’s API dates no rule here earlier than 19 May 2022, even in communities founded in 2008, so the oldest bar collects everything written before then.
The direction is long-running. Across 10,183 snapshots of 2,281 communities’ rule pages from 2011 to 2023, 52% of rewrites increased the community’s rule count.5 The cited set is young as well: 34 of the 138 communities were founded in 2025 or 2026, 10 of them run by a vendor.1
The practical consequence is a date on every reading. r/socialmedia rewrote its whole rulebook on 6 October 2026, inside the month our Panel’s answers cited it, so a register read in September described a different community.
The Communities the Engines Cite Most Leave a Brand the Least Room
These communities matter because the engines quote them. Our Empact Panel puts 500 questions to AI engines, the ones buyers ask when hiring help with AI search visibility, SEO, content, and Reddit marketing.
Our sister company, Qvery, measures the same thing across more categories, so weigh its numbers knowing we own both, and check the data on its own pages. What the two found:
Our count puts job communities among the hardest for a brand to enter. 40 of the 81 in our set prohibit promotion or confine it to a thread or an approval, against a quarter of the founder and startup communities, and none of the 81 lets a brand in without conditions.1
Weighting by what the engines cited sharpens the picture. Of the 1,593 citations our Panel’s answers gave these communities, 36.7% pointed at communities that prohibit promotion outright.1 Of the 56 software threads Qvery found in communities we could read, 20 sat in such communities, and none sat in one that lets a brand promote freely.1
The ten communities our Panel’s answers cited most, and what each lets a brand do:
| Community | Times cited | What its rules let a brand do |
|---|---|---|
| r/SaaS | 543 | One mention or three links every 60 days, disclosed, and no AI-written text |
| r/DigitalMarketing | 173 | No self-promotion |
| r/b2bmarketing | 116 | No posts promoting your company or service |
| r/digital_marketing | 114 | No offers of services, which belong in other communities |
| r/obility | 43 | Product recommendations only inside a technical discussion |
| r/startups | 34 | Only in the monthly Share Your Startup thread |
| r/SaaSMarketing | 32 | A mention only if it is relevant and helpful |
| r/GoogleAnalytics | 29 | No blog spam and no thin attempts to sell |
| r/marketing | 27 | Zero tolerance for self-promotion |
| r/LeadGeneration | 24 | Zero tolerance for self-promotion |
6 of the 10 prohibit promotion or confine it to a thread, and the one at the top allows a single mention every two months.1 Buyers look for exactly this kind of voice: in a Reddit-sponsored survey of 1,202 US business decision-makers, 52% used peer recommendations in early research, as many as used vendor websites.9
At Empact Partners we put a partner’s experts and product into the conversations AI answers draw on, then measure which of them the engines go on to cite. We file that under Generative Engine Optimization (GEO), written as GEO = UGC + Mentions: the public word of real users, plus what independent sources publish about a brand.
The threads are the UGC half, and they sit where a brand has the least room to speak for itself.
When a partner hands us Reddit, we audit the communities its buyers use, file what each one allows, and build a roadmap that puts the partner’s own experts in the threads that fit. Standing reports on community and citation results then show the board which threads the engines quote.
What a Brand Can Do in These Communities
The count leaves three doors open, and all three are narrow:
The last door is the one we can show. A specialized insurance brokerage came to us after five posts in big general subreddits drew nearly 100,000 views and no leads. We moved its Reddit work into 8 to 12 small communities of its buyers, daycare owners among them, and it had nearly 40 qualified leads in a single month.10
What this count cannot settle is how often a community enforces the conditions it publishes. That lives in moderator queues and AutoModerator settings no outsider reads, which is why the reading gets redone before every new community rather than once a year.
If the communities your buyers trust are where the engines find their answers, and your brand has no voice in them, book a call with me. Together we can work out whether we are the right people to run it.
