Product Launch Social Media Checklist for 2026

You built something worth sharing. Now you need people to know about it. A product launch without a social media plan is like shipping a feature without telling anyone — it might be great, but nobody will find it.

This checklist covers every platform that matters for technical product launches. Use it whether you are launching on Product Hunt, posting to Hacker News, or just announcing a new feature to your community.

Two Weeks Before Launch

Draft your core announcement — Write one clear paragraph explaining what you built and why it matters. This becomes the foundation for every platform-specific post.
Prepare platform-specific versions — A tweet thread is not a LinkedIn post is not a Reddit submission. Adapt your message for each platform's style and audience.
Create visuals — Screenshots, a short demo GIF, or a 30-second video. Visual content gets 2-3x more engagement across every platform.
Schedule teasers — Post hints about what you are building. Build anticipation without revealing everything.
Identify your launch platforms — Product Hunt? Hacker News? Reddit? BetaList? Pick 2-3 and prepare submissions for each.

Launch Day: Product Hunt

Submit at 12:01 AM PT — Product Hunt resets daily at midnight Pacific time. Early submission gives you the full day to accumulate upvotes.
Write a compelling tagline — Under 60 characters. Focus on the outcome, not the technology.
Prepare your maker comment — A genuine, detailed first comment explaining your motivation, what makes this different, and what you plan to build next.
Reply to every comment — Product Hunt rewards engagement. Respond quickly and thoughtfully.

Launch Day: Hacker News

Use Show HN format — Title: "Show HN: [Product Name] - [Description]". Keep it factual and understated.
Post between 7-9 AM ET — This is when the US technical audience is most active on HN.
Write a technical first comment — HN readers want to know how you built it, what technical decisions you made, and what problems you solved.
Do not ask for upvotes — This violates HN guidelines and can get your post flagged.

Launch Day: Twitter

Post a thread, not a single tweet — Start with the hook (what you built), then the problem, solution, demo, and call to action.
Include a demo GIF or video — Visual tweets get significantly more engagement in the timeline.
Tag relevant people — If you built on someone's API or were inspired by someone, mention them. They may retweet.
Schedule follow-up tweets — Post updates throughout the day: milestone numbers, user feedback, behind-the-scenes stories.

Launch Day: LinkedIn

Write a personal story — LinkedIn favors personal narratives over promotional content. Tell the story of why you built this.
Post between 8-10 AM in your audience's timezone.
Engage in comments for the first hour — LinkedIn's algorithm weighs early engagement heavily.

Launch Day: Reddit

Find the right subreddit — r/SideProject, r/startups, r/webdev, or niche subreddits related to your product category.
Follow subreddit rules exactly — Many subreddits have strict self-promotion rules. Read them before posting.
Be genuine and helpful — Reddit users can spot marketing from a mile away. Focus on the problem you solve, not features.

After Launch Day

Share milestones — First 100 users, unexpected use cases, what you learned. Building in public keeps momentum going.
Repurpose content — Turn your Product Hunt maker comment into a blog post. Turn your Twitter thread into a LinkedIn article.
Schedule consistent follow-ups — One launch post is not enough. Plan weekly content that keeps your product visible.
