Reddit is one of the most visible places on the internet right now — Google leans on it, and AI assistants quote it constantly. It’s also the fastest place to get your account quietly killed. Here’s how to post the right way: the rules, and the format.
Quick answer
There are two halves to posting well on Reddit. The rules: be a genuine participant, not a walking advertisement — keep self-promotion to roughly 10% or less of your activity, read each subreddit’s rules before you post, build some account age and karma first, disclose your affiliation openly, and never spam the same link across communities. The format: Reddit runs on Markdown, so leave a blank line between paragraphs and lists, use **bold** for key points, - for bullets, > for quoting sources, and lead with your actual answer in the first line.
Do both well and there’s a bonus: because Google and AI tools (ChatGPT, Perplexity, Gemini) cite Reddit heavily, a helpful, well-formatted answer can keep earning you visibility long after you post it.
Most people learn Reddit’s rules the hard way — they sign up, drop a link to their thing, and get removed, downvoted into oblivion, or shadowbanned before lunch. It doesn’t have to go like that. Reddit is genuinely one of the highest-intent communities online, and the price of admission is simple: act like a real person who’s there to help, and format your writing so people actually read it. This guide walks through both, in plain language, with a cheat sheet you can keep.
Part 1 — The Guidelines
The one idea behind every Reddit rule
If you remember nothing else, remember this: Reddit’s whole philosophy is that it’s fine to be a Redditor who has a website — it’s not fine to be a website that has a Reddit account. Every rule below is just a specific expression of that idea. Reddit isn’t anti-promotion; it’s anti-“I only showed up here to sell something.” Contribution earns you the right to occasionally mention what you do. Skip the contribution and even a polite plug reads as spam.
The 90/10 rule (and what it actually means)
The most-quoted guideline is the 90/10 rule: at least 90% of your activity should be real participation — answering questions, joining discussions, being useful — and no more than 10% should point to your own stuff. Reddit retired the formal page years ago, but don’t let that fool you: moderators and automated filters enforce the spirit of it everywhere, and some communities are stricter still.
Here’s what most guides get wrong, though. It isn’t a mechanical “1 promo post per 9 others” you can game. Moderators do a gut check on your whole history. They click your username and scan: is this a person who contributes across lots of topics, or an account that only ever surfaces to drop the same link? Diverse, helpful history makes an occasional mention look natural. A one-note promo history gets you flagged no matter what your ratio says.
Your pre-flight checklist (before you post anything)
Ninety percent of avoidable removals come from skipping this:
- Read the subreddit’s rules. Open the sidebar, the wiki, and any pinned posts. What earns praise in r/SideProject gets you permabanned in r/technology. Note the link policy, allowed frequency, flair requirements, and any banned domains.
- Respect automod. Automated filters are stricter than humans and catch things like new-account status, karma minimums, account age, and domain filters. Even a post mods would love can be auto-removed on a technicality.
- Build a base first. A safe rule: spend your first 30 days commenting only, and reach roughly 100+ comment karma before you post any external link. New accounts dropping links are the single most-caught pattern.
- Know the enforcement escalation. Reddit’s Content Policy (Rule 2) is what sitewide bans hang on — post authentic content, don’t manipulate. Break it and you risk a subreddit ban, a shadowban (your posts silently become invisible to everyone but you), or full account suspension.
What actually gets you banned
The bans almost always trace back to a short list:
- Cross-posting the same promotional link across multiple subreddits in a short window — the fastest route to a sitewide flag.
- Sockpuppeting and vote manipulation — multiple accounts upvoting or backing each other. This is a permanent-ban offence.
- Fake testimonials (“just stumbled on this amazing tool…”). Redditors spot these instantly and the trust damage is permanent.
- Hidden affiliation — burying the fact that it’s your product. Disclose it up front or don’t mention it.
- Reposting removed content without mod permission — treated as ban evasion, which escalates the penalty.
- Promoting in no-promo subs — many ban all self-promotion; posting anyway, however politely, is an instant community ban.
How to mention your product the right way
When you genuinely can help and your product is relevant, here’s the approach that works:
- Find conversations, don’t manufacture them
Search for threads where people already describe the problem you solve, and answer those. Joining an existing question beats creating a thread about yourself every time. - Lead with real value
Give a complete, useful answer that stands on its own even if you never mention your product. Earn the read before you earn the click. - Disclose in plain language
Something like: “Full disclosure — I built one of the tools in this space. But here’s what I’d suggest even if it didn’t exist…” Honesty is respected; stealth is punished. - Keep the ratio honest over time
A sustainable habit is roughly five to nine genuinely helpful contributions for every one that links to your own thing. Trust compounds — accounts that give first get real leeway later.
Part 2 — The Correct Format
Why formatting decides whether you're even read
Reddit users scan before they commit. People read online in an F-shaped pattern — eyes down the left edge, catching the first words of each line — and decide in about two seconds whether a comment is worth reading fully. A wall of text signals “low effort” even when the idea is brilliant. Formatting gives readers entry points: bolded key phrases, bullets, clear breaks. It’s telling that only a tiny fraction of top-voted comments are plain text — scannable structure is what gets upvoted, saved, and (increasingly) quoted by AI.
Rich Text vs Markdown mode
Reddit’s composer defaults to a Rich Text editor with toolbar buttons — fine for quick formatting. But for real control (and for pasting clean text without surprises), switch to Markdown mode, usually an option near the composer. Markdown lets you type the formatting directly and see exactly what you’ll get.
The Reddit Markdown cheat sheet
Type the syntax on the left; Reddit renders the result. Save this.
| Element | Type this | Notes |
|---|---|---|
| Bold | **bold** | Double asterisks. Most-used emphasis. |
| Italic | *italic* | Single asterisk (avoid mid-word underscores). |
| Bold + italic | ***both*** | Triple asterisks. |
| Strikethrough | ~~struck~~ | Double tildes. |
| Inline code | `code` | Backticks. Good for commands or literals. |
| Heading | ## H2 / ### H3 Hash + space. | Stick to H2/H3 in long posts. |
| Bullet list | - item | Dash + space. Blank line above the list. |
| Numbered list | 1. item | Number, dot, space. |
| Blockquote | > quoted | For quoting a source or another comment. |
| Link | [text](https://url) | Descriptive text, not a raw URL. |
| Code block | ``` lines ``` | Or indent 4 spaces. See old-Reddit note below. |
| Spoiler | >!hidden!< | No spaces inside the markers. |
| Superscript | text^(note) | Handy for asides and footnotes. |
The formatting mistakes almost everyone makes
- Missing blank lines — the #1 error. Reddit needs a blank line between paragraphs and before any list or blockquote. Without it, everything collapses into one run-on block. Press Enter twice.
- Pasting from Word or Google Docs. They inject “smart quotes” and hidden characters that silently break Markdown. Paste as plain text, then format.
- Mid-word underscores. Reddit treats
_inside a word as a literal character, sosuper_importantwon’t italicize. Use asterisks for partial-word emphasis. - Forgetting old Reddit. Tables and triple-backtick code blocks don’t render on old.reddit.com. If part of your audience uses it, add a plain-text fallback.
- Over-formatting. Bold on every sentence, headers on a three-line comment, quotes nested four deep — all make things harder to read. Formatting is seasoning: a little helps, a cup ruins it.
- Skipping Preview. Always preview, and where possible check on mobile — some elements render differently there.
The anatomy of an answer that gets upvoted (and cited)
This structure works on Reddit for the same reason it works for AI answer engines — it leads with the answer and is easy to extract:
Model comment structure
One or two sentences that directly answer the question, up top.
Then a little context in a short paragraph. Keep it to 2–3 sentences so it stays scannable.
– A key step or option
– Another one
– The gotcha most people miss
> If you’re quoting a source or another comment, put it here.
Full disclosure: I work in this space — but the above holds regardless. Hope it helps.
Notice the shape: the direct answer first, supporting detail in small chunks, a scannable list, a quoted source, and an honest disclosure at the end. That’s a comment people thank you for — and exactly the kind of self-contained, well-structured answer that Google and AI tools like to quote.
Why doing this well is also an AI-visibility strategy
Here’s the part that matters for anyone thinking about marketing. Reddit isn’t just a community anymore — it’s a source. Google surfaces Reddit threads prominently, and AI answer engines cite Reddit discussions heavily when people ask for recommendations and real-world experience. So a genuinely helpful, rule-compliant, well-formatted answer isn’t a throwaway comment; it’s an asset that can keep getting quoted for months.
On today’s internet, a great Reddit answer is earned media that both Google and AI can read.
That makes compliant Reddit participation a legitimate slice of a modern search strategy — the same “be the credible source” logic behind the AI-search trust gap and why the individual is becoming the strategy. If being cited by AI is a goal, it’s the discipline behind our GEO and LLM SEO work, and it complements how you earn placement in Google’s AI Overviews and shape how ChatGPT describes you. Treated as community-first engagement, it also sits naturally alongside social media marketing — just never as a place to dump links.
The takeaway is refreshingly old-fashioned: be helpful, be honest, and write so people can read you. Reddit rewards exactly the behaviour that also happens to win in AI search.
Frequently asked questions
Is self-promotion allowed on Reddit?
Yes, when it’s authentic, transparent, and useful. Reddit bans spam and deception, not promotion itself. The principle: be a Redditor who has a website, not a website with a Reddit account. Contribute real value first, disclose your affiliation, and only mention your product when it genuinely answers the question.
What is the 90/10 rule on Reddit?
The norm that no more than ~10% of your activity should be self-promotional, with 90%+ genuine participation. Reddit retired the formal page, but mods and automod still enforce its spirit. It’s judged on your whole history, not one post’s ratio — and some subs ban promotion entirely.
How long before I can post links on Reddit?
A safe rule is 30 days of commenting only, reaching around 100+ comment karma before posting external links. Many subreddits enforce karma and account-age minimums via automod, so new accounts dropping links get caught most often.
What formatting does Reddit use for comments?
Markdown. Use the Rich Text buttons or switch to Markdown mode: **bold**, *italic*, > for blockquotes, - for bullets, [text](url) for links, ## for headings. The key rule: leave a blank line between paragraphs, lists, and blockquotes.
Why do my Reddit comments run together?
Usually missing blank lines — Reddit needs one before lists and blockquotes and between paragraphs. Other causes: pasting from Word/Google Docs (smart quotes break Markdown) and mid-word underscores (ignored). Always use Preview.
Does posting on Reddit help SEO or AI visibility?
Yes. Google surfaces Reddit heavily, and ChatGPT, Perplexity, and Gemini cite it frequently. A helpful, well-formatted, compliant answer can be quoted by both for a long time, making compliant Reddit participation a genuine, earned form of AI visibility.
Being cited across Reddit, Google, and AI answers is a strategy, not an accident. We help brands earn credible visibility in the places people (and AI) now look first — the right way, without risking bans.
