Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for product, audience, and brand voice.

Identify:

• Goal: Leads, community growth, brand awareness
• Platform fit: Indie Hacker, HN, Reddit, Discord, vertical forums
• Timeline: One-time launch vs sustained (4-6 months for Indie Hackers)

Forum Types

Platform	Audience	Use
Indie Hacker	Indie makers, founders	Sustained engagement; authentic journey posts; ~23% conversion vs PH 3%
Hacker News	Tech, startups	Show HN launch; ~1,300 posts/day; front page = luck + timing
Hackernoon	Dev, tech readers	Content distribution
Industry forums	Niche verticals	Discount codes for leads; search "[industry] forum"; post event/activity promotion; see discount-marketing-strategy for code strategy
Reddit	Subreddit-specific	See reddit-posts; 90/10 rule; 29+ posts for traction

Hacker News Launch

Practice	Guideline
Title	"Show HN: [Product] - [specific problem solved]"; honest, no clickbait
Timing	Tue-Thu; peak US hours; avoid weekends, Mon, Fri
First comment	Invitation to engage; product status (beta/MVP); differentiated solution; try-it link
Assets	Live demo, GIFs, screenshots, 30-60s demo video
Expectation	Traffic spike, not sustained growth; partly luck-dependent

Indie Hackers Best Practices

• Sustained engagement: 4–6 months; not a one-time launch
• Content: Authentic journey posts; product "sprinkled within"; avoid heavy promotion
• Result: ~23% conversion vs Product Hunt ~3%; organic traffic from authentic sharing

Community Invitation Tactics

Channel	Method
Welcome email	Post-signup automation; 4x open, 5x CTR vs regular campaigns
Homepage CTA	Button, popup, banner; above-the-fold upgrade CTA
In-site placement	High-visibility areas; user-focused sections (e.g. dashboard, settings)
Banner	Homepage, carousel below hero
Registration emails	Success/confirmation email with community link
EDM campaign	Newsletter + banner, interview-for-membership
Discord	Post event/community info; founder engagement 2-3h/day
Vertical forums	Search "[industry] forum"; post event/activity promotion
Post-login form	In-app signup form shown after login; high-intent placement

Welcome email best practices: One clear CTA per email; front-load value in subject; personalize (signup source, interests); link to best content, events; ask questions (~75% reply rate). Automated 2-4 email sequence.

Vertical Community Channels

Principle	Guideline
Target	Find channels where target audience gathers
Niche over broad	Industry-specific subgroups; avoid mass posting
Caution	Mass posting risks removal; match community tone; choose wording carefully
Examples	Reddit subreddits, Discord servers, Quora, X, Hacker News, Stack Overflow, niche B2B communities
Regional	Large communities by locale—event/activity promotion; target vertical channels within each; see localization-strategy

Community-led growth: Engage before promoting; build trust; contribute value first.

Natural Traffic (Complementary)

Channel	Use
Hashtags	Social tag optimization
Facebook groups	Indirect referral
Giveaways	Attention and conversion

Brand Basics (Encyclopedia, Q&A)

Platform	Use
Wikipedia	Global; neutral, cited content; brand credibility
Quora	Q&A; brand discussion, thought leadership, long-term SEO
Stack Overflow	Tech/dev; expertise signals, backlinks
Regional	Local encyclopedias and Q&A by locale; verified credentials; see localization-strategy

Wikipedia: Neutral language, credible references, no promotional content. Regional platforms require verified credentials; prioritize local search share. Free and sustainable; supports long-term conversion while search habits persist.

Output Format

• Forum selection and approach (HN vs IH vs industry)
