Subreddit Rules: The Ultimate Guide for Marketers

I got banned from r/SaaS on my second day of using Reddit for marketing. Not shadowbanned. Fully banned. The mod sent me a one-line message: "Read the rules." That was it.

I deserved it. I'd dropped a link to our landing page in a comment thread without reading a single rule on the sidebar. I didn't even know the sidebar existed. If you're a marketer trying to use Reddit, this post is everything I wish someone told me before I made that mistake.

Every subreddit is its own country

This is the part most marketers don't get. Reddit isn't one platform with one set of rules. It's thousands of communities, each with their own norms, their own culture, and their own rulebook. What flies in r/entrepreneur will get you banned in r/marketing. What's encouraged in r/startups will get you mocked in r/smallbusiness.

Before you post anything in a subreddit, you need to read that subreddit's rules. They're usually in the sidebar on desktop or in the "About" tab on mobile. Some subreddits have two rules. Some have fifteen. Some have rules that aren't written down anywhere but everyone seems to know. You figure those out by lurking.

I spent about a week just reading threads in the subreddits I wanted to participate in. I looked at what got upvoted, what got removed, what got people yelling at each other. That week of doing nothing was more valuable than the month I spent after blindly posting links.

Moderators are volunteers and they don't owe you anything

This one took me a while to internalize. The people enforcing subreddit rules aren't Reddit employees. They're volunteers. They moderate because they care about their community, not because they're getting paid. Some of them moderate multiple subreddits and deal with hundreds of spam posts a day.

So when you show up with your "10x your revenue with this one weird trick" post and it gets removed, don't message the mod team asking why. Don't argue. Don't appeal. Just read the rules you should have read in the first place and try again. I've seen marketers get permanently banned because they got into arguments with mods. You will never win that fight. The mod can remove you with one click and go back to eating lunch.

Being respectful to mods has actually opened doors for me. I've had mods in a couple subreddits reach out to tell me my posts were good and ask if I wanted to do an AMA. That doesn't happen if you treat their community like your personal billboard.

The 90/10 rule is real

There's an unwritten standard across Reddit that roughly 90% of your activity should be genuine participation and maybe 10% can be self-promotional. Some subreddits enforce this explicitly. Most enforce it implicitly — meaning if your post history is nothing but links to your own stuff, people will call you out and mods will notice.

I follow something closer to 95/5 honestly. For every post where I mention something related to our product, I've left dozens of comments helping people with questions I actually know the answers to. I answer questions where our product isn't relevant at all. I share resources from competitors. I tell people when they don't need a tool like ours.

This sounds counterintuitive if you're used to other marketing channels. But Reddit users are allergic to being sold to. They can smell a pitch from three paragraphs away. The only way to earn the right to occasionally mention your own work is to be genuinely useful first. Not "useful" as a strategy. Actually useful.

Read the sidebar before you post anything

I keep coming back to this because it's the single most important thing. The sidebar. Read it. Every subreddit has one. It tells you what's allowed, what's not allowed, what format your posts should follow, what flair to use, whether you need minimum karma to post, whether self-promotion is banned entirely.

Some subreddits only allow self-promotion on specific days. Some require you to have been a member for 30 days before posting. Some ban link posts entirely. Some require you to add your post to a weekly megathread instead of creating a new one. You won't know any of this unless you read the sidebar.

I keep a simple doc where I track the rules for every subreddit I participate in. It takes five minutes to set up and it's saved me from getting banned more times than I can count.

What happens when you get it right

After I got banned from r/SaaS, I made a new account and started over. I spent two weeks just commenting and helping people. I read every rule in every subreddit I joined. I never mentioned our product unless someone specifically asked about the kind of tool we make.

Three months later, Reddit was our third-largest source of qualified leads. Not because I figured out some hack. Because I stopped treating Reddit like a marketing channel and started treating it like a room full of people who are really good at spotting fakes.

The rules exist for a reason. Follow them and the platform works. Ignore them and you'll spend more time getting banned than getting customers.
