TL;DR
- Reddit hates self-promotion — but loves genuine value
- Find your subreddits first, lurk 2 weeks before posting
- 80% give value, 20% soft-sell (never hard sell)
- Best posting time: 6-8 AM PST for US audiences
- Use Reddit's own tools: search, karma, community rules
Why Reddit Marketing Matters
Reddit has 1.7 billion monthly visits. It's where early adopters hang out, decisions get influenced, and products go viral overnight.
But here's the catch: Reddit users hate marketers. Post the wrong way and you'll get banned, downvoted to oblivion, or worse — your brand becomes a meme for all the wrong reasons.
I've used Reddit to help grow AFFiNE from 0 to 33k GitHub stars and launch 30+ products to Product Hunt #1. Here's what actually works.
How to Find the Right Subreddits
Before posting anything, find where your audience hangs out.
Step 1: Search Reddit directly
Use Reddit's search with your keywords. Look for subreddits with:
- 10k-500k members (large enough for reach, small enough to get noticed)
- Active daily posts
- Rules that allow sharing tools/resources
Step 2: Use Reddit List
Reddit List categorizes subreddits by topic and activity. Filter by your niche.
Step 3: Check competitor mentions
Search your competitors on Reddit. Which subreddits discuss them? Those are your targets.
Pro tip: Make a spreadsheet with subreddit name, member count, rules, and posting frequency. You'll need it.
The 2-Week Lurking Rule
Never post immediately after joining. Here's why:
- New accounts get flagged — Mods check account age and karma
- You'll miss community norms — Each subreddit has unwritten rules
- You need karma first — Comment genuinely on other posts, build up your account
During these 2 weeks:
- Read top posts of all time
- Note what gets upvoted vs downvoted
- Study how others share their work (if allowed)
- Comment helpfully on 5-10 posts
Writing Posts That Don't Get Banned
The 80/20 Rule
80% pure value, 20% soft mention of your product. Never reverse this.
Bad example:
"Check out my new tool that does X! Link in comments."
Good example:
"I analyzed 100 Product Hunt launches and found 5 patterns that #1 products share. Here's what I learned... [detailed breakdown] ... I'm building a tool based on these findings, happy to share if anyone's interested."
Structure That Works
- Hook — Intriguing statement or question
- Value — 80% of your post, pure information
- Soft CTA — "Link in comments if useful" or "Happy to share more"
What to Avoid
- ❌ Clickbait titles
- ❌ Direct links in post body (use comments)
- ❌ Posting the same content to multiple subreddits
- ❌ Asking for upvotes
- ❌ Arguing with critics
Best Times to Post
For US-focused subreddits:
- 6-8 AM PST — Catches morning scrollers
- Avoid weekends — Lower engagement for B2B content
For global tech subreddits (r/programming, r/startups):
- Tuesday-Thursday performs best
- Post early US morning so it has time to gain traction

Real Example: How We Used Reddit
When launching AFFiNE, we didn't spam r/productivity. Instead:
- Week 1-2: Lurked, commented on productivity discussions
- Week 3: Posted a genuine question about workflow challenges
- Week 4: Shared a detailed "how we built X" technical post in r/programming
- Week 5: Soft-launched with "open source alternative to Notion" positioning
Result: Front page of r/programming, 2000+ upvotes, thousands of GitHub stars in 48 hours.
The key: We gave value first, then introduced our product as a natural solution.
Summary
Reddit marketing works when you:
- ✅ Find the right subreddits
- ✅ Lurk and understand culture first
- ✅ Give 80% value, 20% soft promotion
- ✅ Post at optimal times
- ✅ Engage genuinely with feedback
The goal isn't to "market" on Reddit. It's to become a valuable community member who happens to have built something useful.
