How to Write Reddit Comments and Posts That Stick
Most marketing advice on Reddit is guesswork, but we think we’ve fixed that. We looked at the comments and posts on reddit made from Engain over the last month and compared the ones still active to the ones moderators and AutoMod removed. The differences are consistent and most are not due to your product.

Delete Test
Run the delete test on every draft before it goes out. It takes three steps.
First, write the comment as you normally would.
Second, delete your brand name and any sentence that only exists to introduce it.
Third, read what's left and ask whether it still answers the question the person asked.
From the moderator's perspective, it would seem like it is a contribution to the discussion. If it falls apart and isn’t able to convey any sort of benefit, or lacks structure due to removal of the brand name, it creates the appearance of an advertisement, and a moderator will likely take it down. That single test explains most removals.
Answer coherently to the Reddit discussion
Plenty of removed comments answered a nearby question instead of the real one. It's one of the most common ways a comment gets pulled. The brand mention is light, the tone is helpful, and the comment still sidesteps what the person asked. Moderators pick up on that gap fast.
When your product solves a problem next to the one being discussed, the thread looks like a hook rather than a conversation. Wait for a thread where your answer is the answer or create it on your own using Engain.
Name the alternative solutions or businesses
This concept comes down to naming more than one product, competitor, or brand mention. Not to promote or defame another company, but to create context around your recommendation or content.
The contrast with removals. Nearly every mod-removed comment named exactly one product, the client's. That shape is recognizable in about a second, before anyone reads the argument.
Why does it read that way? Someone who actually solved the problem knows what else exists. Skipping straight to one name with no context suggests the writer arrived with that name already in hand.
Make the mention conditional
Strong comments hand the reader a filter. "If you're mostly managing a catalog, look at X." "If you have tribal enrollment, this scholarship fund applies." "If it's your first time, a small-group option is worth the extra drive." A conditional mention says the product isn't for everyone, which is both true and disarming.
Admit one real downside
Our favorite surviving comment ended with a warning: the approach works, but now you own and maintain a crawler. Another said a tool was not a drop-in replacement.
Nothing builds trust faster than telling someone what's annoying about your own suggestion. It also gives moderators something an advertisement would never write.
Match the room, and keep it short
Most surviving comments are one to four sentences. Lowercase and constructed loosely regarding its topic.
Short fragments work well: "Same error here this morning. Cleared on its own after a few hours. Not your key."
Length matters more than people expect. On one thread, a long comment full of prices and phrases like "hidden gem" and "generous return policy" was filtered automatically, while a two-sentence version on the same thread went through untouched.
Patterns get caught, not just posts
Three comments about the same browser landed in the same subreddit within about a minute of each other; two of them nearly word for word get removed easily as well. A moderator doesn't have to evaluate one comment when they can see a cluster.
Space mentions out, at most one per subreddit every few days, and never reuse an opener. It also helps to leave comments that mention nothing at all, so the account reads like a person rather than a billboard.
Posts carry more risk than comments
A great post can still be removed. The strongest post we read was a detailed how-to on finding influencers, about 1,200 words of real method, with the product named only at the end. It went live, picked up upvotes and a reply, and came down five days later. Some clients would call that a win, but others' goal is for a post that stays up and keeps pulling traffic from that subreddit months from now.
The survivors look boring on the surface. Plain lowercase titles, usually a question with a specific place or product in it. An opener that drops you mid-thought into a problem people recognize, no throat-clearing. Then real detail, the kind you only have if you've actually done the thing. They end on a real question too, which is mostly why they get replies at all.
The checklist
Answer the exact question first, before any brand appears.
Name an alternative, or make the mention conditional.
Admit one real tradeoff.
Keep it to one to four sentences, in the sub's voice.
No prices, superlatives or sales vocabulary.
Post on threads from the last week or two.
One mention per subreddit every few days, with a fresh opener each time.
Mix in comments that mention nothing.
Never invent an experience, a persona or a customer.
Delete the brand name and reread. Still useful? Post it.
