What are Reddit's actual rules on self-promotion?
There are two layers. Reddit's site-wide Content Policy asks people to post authentic content in communities where they have a personal interest, and prohibits content manipulation, which it says includes spamming, vote manipulation, ban evasion and subscriber fraud. Reddiquette, Reddit's etiquette guide, adds the spirit of it: it's fine to be a person on Reddit who has a website, not a website with a Reddit account.
The second layer is each subreddit's own rules, shown in the sidebar or "About" tab. These vary a lot, even between communities on the same topic:
| r/aeo | Recommendations are welcome; no spam or repeated self-promotion; contact mods if unsure | Disclosed mentions are fine when they genuinely help |
|---|---|---|
| r/SEO_for_AI | Be honest when self-promoting; support your claims | Mention your product with disclosure and evidence |
| r/GEO_optimization | No spam, no blatant self-promotion | Help without naming your brand |
| r/DigitalMarketing | No self-promotion, no posting services; posts clearly written by AI are deleted and the user banned | Value only, in your own words, no brand |
Which account should a brand use?
Usually a real person's account, not a brand account. People respond to people. A founder, product lead or support engineer answering under their own name, with a clear line about where they work, is trusted far more than "BrandName_Official".
- Use an account with history. Many subreddits automatically hide comments from new or low-karma accounts. An older account with normal activity elsewhere looks like what it is: a real person.
- Don't wipe old activity. A profile that suddenly switches from hobbies to marketing a product looks repurposed. Keep posting normally in your usual communities.
- Put your affiliation in your profile. A short bio like "Building [product]" makes your disclosure permanent and visible to anyone who checks.
What does a good brand comment look like?
In our analysis of 29 AI visibility threads, the vendor replies that earned upvotes had the same shape. Use it as a template:
- 1Disclose in the first line
"I work on [product], so I'm biased." or "Full disclosure, I'm building [product]." Say "I'm building it", never "I've used it", if it's yours.
- 2Answer the actual question first
Give advice that helps even if the reader never buys from you: steps, numbers, what you'd check, what went wrong for you.
- 3Name alternatives fairly
Mentioning competitors where they fit is the clearest signal that you're helping, not selling.
- 4Mention your product once, at the end, if at all
One line, with what it does. No link unless someone asks, or the subreddit clearly allows it.
- 5Stay for the replies
Answer follow-up questions. A good reply to someone's question often earns more trust than the original comment.
What gets brands banned on Reddit?
- Second accounts that praise your product. Some agencies sell networks of aged accounts posing as customers. It's content manipulation under Reddit's policy, it gets spotted, and the backlash ends up in the very threads AI reads.
- Vote manipulation. Upvoting your own comments from other accounts, or asking colleagues to, is explicitly prohibited.
- Posting AI-written text where it's banned. Some subreddits ban users for it. Write in your own words.
- Dropping links everywhere. Links in comments pass little search value and are the easiest thing for filters to flag.
- Bursts of activity. Five branded comments in an hour across one subreddit reads as a campaign. Two or three thoughtful comments a day, mostly brand-free, is plenty.
Is it worth the effort?
For most brands, yes, if you treat it as a long-term habit. Reddit threads rank in Google for comparison searches and are among the sources AI assistants cite; in Ahrefs' September 2026 data, reddit.com was the most cited domain in ChatGPT answers.

Frequently asked questions
Can brands promote themselves on Reddit?
Yes, within each subreddit's rules. Reddit's Content Policy prohibits spam and content manipulation, and many subreddits limit or ban self-promotion. Brands that disclose their connection and genuinely help are generally welcome.
Is the 90/10 rule an official Reddit rule?
No. It's a widely cited community guideline that no more than about 10% of your activity should promote your own things. Reddit's Content Policy doesn't set a percentage, and some subreddits are much stricter.
Should I use a brand account or a personal account on Reddit?
Usually a real person's account with history, with their role disclosed in comments and in the profile bio. People trust people more than brand accounts.
Can I post links to my website on Reddit?
Only where the subreddit allows it, and ideally only when someone asks. Links are the easiest thing for moderators and filters to flag, and they pass little search value.
Is it OK to use AI to write Reddit comments?
Some subreddits delete AI-written posts and ban the user. Even where it's allowed, comments in your own words read better and get a better response.
