You've built your Chrome extension and published it to the Web Store. Now you need users, but you don't have a marketing budget. Every article about marketing talks about ads, influencers, or paid tools that cost money you don't have. The good news is that some of the most effective Chrome extension marketing costs nothing except your time.
This is a systematic seven-day plan using free channels that actually work. Each day focuses on specific platforms and tactics that drive real users. The plan assumes you can dedicate 2-3 hours daily to marketing. By the end of these seven days, you'll have promoted your extension across multiple channels, built initial momentum, and established marketing systems that continue working long after the week ends.

Day 1: Optimize Your Foundation
Before promoting anywhere, ensure your Chrome Web Store listing converts visitors into users. Write a clear title that includes your main keyword and describes what your extension does. Rewrite your description's first paragraph to immediately explain the problem you solve and who you solve it for. Create 3-5 screenshots showing your extension solving actual problems with brief text annotations.
Set up basic analytics so you can track where users come from this week. Build a simple landing page using free tools like Carrd or notion.site if you don't have one. It doesn't need to be fancy, just a clear headline, benefits, screenshots, and a call-to-action linking to the Chrome Web Store.
Day 2: Launch on Product Hunt
Product Hunt remains the best free launch platform for Chrome extensions. A good Product Hunt launch can drive 50-200 installs in a single day. Prepare your launch the night before so you can post at 12:01 AM Pacific Time when the new day starts. Write a compelling tagline under 60 characters, create a clean 240x240px thumbnail, and focus your description on the specific problem you solve.
Engage with every comment throughout the day. Set phone notifications so you can respond quickly to questions, thank supporters, and address concerns. Ask friends to upvote and comment early, as initial momentum helps you climb the rankings. Many Product Hunt users will install, try your extension, and return with feedback.
Day 3: Target Reddit Communities
Reddit offers direct access to your exact target users if you approach it correctly. Find 5-10 communities where your target users gather. For productivity extensions, try r/productivity or r/getdisciplined. For developer tools, check r/webdev or r/javascript. Read each subreddit's rules carefully as many have specific days for self-promotion.
Share your story, explain the problem you're solving, discuss challenges you faced building it, and ask for feedback. Frame your post as sharing your journey, not just promoting a product. Engage authentically in discussions beyond your own post. Done right, Reddit can drive 20-40 highly targeted installs from users genuinely interested in your solution.
Day 4: Personal Network Outreach
Your personal network is more valuable than you realize. Make a list of 30-50 friends, family, former colleagues, and professional connections who might benefit from your extension. Don't send mass emails. Take time to reach out individually explaining specifically why you think your extension would help them based on what you know about their work.
Ask them to try it and provide honest feedback. Most importantly, ask if they know anyone else who might find it useful and if they'd be willing to share it. When someone in your network loves your extension, they'll naturally mention it to colleagues, post about it on social media, or recommend it in conversations.

Read MoreDay 5: Community and Forum Posting
Beyond Reddit, search for industry-specific Slack groups, Discord servers, Facebook groups, and niche forums related to your extension's category. Join 5-10 active communities where members genuinely help each other. Don't immediately post about your extension. Spend time reading discussions, understanding community norms, and introducing yourself first.
When you do share, do it in designated promotion channels or when genuinely relevant to ongoing discussions. Look for people asking questions your extension solves and provide a helpful answer first, then mention your extension as an option. A Discord with 500 active daily users beats a Facebook group with 50,000 inactive members.
Day 6: Content Creation and Sharing
Content creation drives sustainable long-term user acquisition. Write a blog post about why you built your extension, what problem it solves, and lessons you learned during development. Post this on Medium, Dev.to, or Hashnode. Create a Twitter thread documenting your building journey with screenshots of your extension and insights about what worked in getting users.
Record a simple video walkthrough showing how to use your extension using screen recording with voiceover. Upload to YouTube with a descriptive title including keywords people search for. This content works for you continuously, driving users long after you publish it.
Day 7: Social Proof and Milestone Celebration
By day seven, you should have your first users and hopefully some positive feedback. Reach out to users who've been active or left positive reviews and ask if they'd share a brief testimonial. Add these testimonials to your Chrome Web Store description and share them on social media.
Post an update celebrating your first week's progress with specific numbers: "Hit 75 users in my first week!" Share what strategies worked best and thank the communities that supported you. This meta-content about your launch success often gets shared because people love supporting indie makers.
What Happens After Day 7
These seven days establish marketing systems that continue working beyond the initial week. The content you created keeps attracting users through search. The communities you joined become ongoing promotion channels. The network you activated continues spreading word-of-mouth. Don't stop after seven days. Pick the 2-3 channels that worked best and continue focusing there.
Consistency matters more than intensity. Marketing 30 minutes daily beats one intense week followed by nothing. Set a sustainable schedule for ongoing promotion. Build marketing into your routine rather than treating it as a one-time launch push.

Measuring Your Success
Track installs from each channel so you know what worked. Use unique UTM parameters in links you share on different platforms so Google Analytics can track sources. Note which Reddit posts drove the most traffic, which communities were most receptive, and which content got the most engagement.
Success isn't just install numbers. Pay attention to which channels drove the most engaged users. Ten users who become daily active users matter more than 100 who install and never return. Your first week's numbers establish baselines for improvement.
Common Mistakes to Avoid
Don't spam the same message across every platform. Tailor your message to each community's culture and norms. Don't disappear after initial posts. Engagement matters as much as posting. Respond to comments, answer questions, and participate in discussions beyond your own promotion.
Don't give up if day one or two don't drive massive numbers. Marketing compounds over time. A blog post might drive one user today but twenty monthly within six months as it ranks in search. Don't neglect your existing users while chasing new ones. Happy users become your best marketers.
Start Your Seven Days Now
Zero budget marketing forces creativity and authenticity that paid marketing can't replicate. Many successful Chrome extensions built their entire user bases through free marketing. They systematically promoted through free channels, created helpful content, and built genuine communities.
Start your seven-day plan today. Don't wait for the perfect moment or until you've built more features. Market what you have now and improve based on user feedback. You have seven days and zero dollars. That's all you need to start building real momentum.
