A Reddit reply that does not read like an ad answers the question in the first two lines, adds one detail that only someone with experience would know, and mentions your business last, briefly, with a plain note that it is yours. If the reply would still be useful with your business cut out of it, it is not an ad.
Below is the anatomy of that reply, followed by a bad version and a better version written for the same thread. The business and people are made up. The structure is what you can copy.
Read the whole thread first
Most bad replies come from answering the title. Open the post and read the body, then read the other comments. You are looking for details the title left out: the poster's budget, their city, what they have already tried, a deadline, a landlord or spouse constraint. You are also checking whether someone has already given the answer you were about to give. If they have, adding "same here" is noise. Add the thing they missed, or stay out.
Read the poster's other posts in that community, too, if the thread is about a real job. Two minutes of context tells you whether they are a homeowner with a leak or a landlord with eight units, and the reply is different for each.
Answer the question in the first two lines
People on Reddit scan. The first two lines decide whether they read the third. Put the actual answer there: yes, no, it depends on X, probably the capacitor, expect about this much. Save the reasoning and caveats for after.
This also makes your reply easy for the original poster to act on, which is the only metric that matters. A thread starter who got a usable answer will often upvote it, thank you, or write back with a follow-up. A reply that opens with "Great question! At our company we..." gets scrolled past.
Share one specific detail from experience
A single concrete detail separates a person from a pitch. Not a list of five tips, one real thing: a number you have seen, a mistake you watched a customer make, a measurement, a brand-neutral rule of thumb. "Most basement leaks I've seen come from the gutter discharging two feet from the wall, not from the foundation" is the kind of sentence that makes a reader trust the rest.
Make sure the detail is true. Reddit readers will catch an invented figure, and an owner who makes up numbers to sound credible loses more than one thread. If you do not know a number, say what you do know. Personalisation at low volume makes the same point about outbound email: one real, checkable specific beats five vague compliments.
Mention your business only if it fits
Often the right move is no mention at all. If the poster is in another country, or wants a free how-to answer, or the community bans promotion, your business has no place in the reply. Give the answer and leave.
When it does fit, because the poster asked for a recommendation or specifically for someone to do the work, mention the business in one clause, after the help. And keep the link out of it unless it answers a question they asked.
Disclose that it is yours
One sentence: "I own a small waterproofing company, so keep my bias in mind." That is all. It matters for two reasons. It is the honest thing to do, and it is what makes the community willing to hear a recommendation from an owner. Hiding it is the quickest route to a thread of people pointing out your history and reporting you.
It also helps with Reddit's own rules. Reddit's site-wide rules ban spam and manipulating votes, and many communities require owners to say so when they mention their own work. Check each subreddit's rules. For the situation where the recommendation is for yourself, Reddit recommendation threads when you sell the product goes further.
Keep it short
Aim for something a person could read in twenty seconds on a phone. Three to six sentences is usually right. If the answer needs more, break it into short paragraphs and lead with the part the poster most needs. A wall of text signals either a copy-paste or a salesperson, and often both.
A bad reply and a better one
The thread: a homeowner writes, "Basement gets damp every spring and smells musty. Gutters are clean. Got a quote for interior drain tile at $9,800. Does that sound right?"
The bad reply, from Okafor Basement Systems:
Hi! Sorry to hear about your basement. At Okafor Basement Systems we have helped over 500 homeowners keep their basements dry. We offer free estimates, a lifetime warranty, and financing! Visit okaforbasements.example or call 555-0142 today!
There is no answer in it, the numbers can't be verified, it has a link and a phone number, it reads the same in every thread, and it never says whether $9,800 is reasonable. It will be removed or ignored. Also, "over 500 homeowners" is exactly the kind of claim to leave out unless you can prove it.
The better reply, from Chidi at the same company:
$9,800 isn't crazy for interior drain tile, but it depends on linear feet and whether it includes a sump pump and a discharge line. Ask for the footage and the pump model in writing. Before signing, check the grade outside: if the soil slopes toward the house, fixing that, plus extending the downspouts six feet or so, can solve spring dampness for a fraction of the price. Damp plus a musty smell usually means humidity, not a leak. A $200 dehumidifier and a hygrometer will tell you which. I own a small basement waterproofing company, so I'm biased toward the work, but I'd try the cheap fixes first. Happy to look at photos if you want to post them.
It answers the money question first. It gives a number-free but checkable test, it says something that costs the author a sale, it discloses the business once, and it offers help without a link. That last move, telling someone to try a cheaper option, is what makes the person trust the rest, and it is frequently what brings the job. When the homework is done, a poster who wants it done properly knows who to ask.
You post it, in your own voice
Draft however you like, but the account that posts should be yours. Conversations, inside Rocketship, finds Reddit threads where people ask for what you sell and drafts a reply and a message in your voice from what it knows about your business. You read the draft, rewrite the lines that do not sound like you, and post from your own account. It never posts, messages or votes for you. Treat the draft as a starting point, and delete anything you would not say out loud.
Once a reply works, the next step is usually a message. How to DM someone on Reddit without being spammy covers when that is welcome. And because new-looking businesses lose trust easily, cold email that is not spam and looking bigger without lying about it apply the same ideas away from Reddit.
Writing the reply is the easy part once you have found someone to write it for. Rocketship finds the buyers, emails them from your own Gmail, follows up, and books the meeting on its own. Plans that get you customers start at $24.99 a month (Launch), and every monthly plan starts with a 7-day free trial, card required. Meet the AI workers that do the repeat work.
