🚀 How We Hit $5,000+ MRR Without Spending a Penny on Ad

Hey Indie Hackers đź‘‹ My name is Shashank.

I am the creator of API.market, a global marketplace for AI models & APIs. I knew there were going to be a lot of AI agents in the future, and to get anything done AI agents use APIs. Hence, I knew that there needed to be a marketplace for APIs/AI models that can be used by various developers.

How did we do it?
-> Fix SEO!! (Check Google Search Console and fix all errors)
-> Make sure developers (your customers) find value fast and stay on the page.

  • So the entire API.market is designed like an e-commerce platform. You see the pricing card on the right, details in the center, and reviews.
  • Every API is pre-configured, so you can try it in under 30 seconds using API Playground.
  • Cross-links and similar APIs to help developers navigate the platform.

How did I do this?

  • Built backlinks.
  • Posted every day on Reddit.
  • Optimized content for AI models and SEO.
  • Record everything and watch users using the platform using Microsoft Clarity

🎯 Results

  • 100% Organic growth.
  • 300+ APIs with 100+ AI models.
  • 60% of traffic from Google.
  • Over 6,000 B2B Users.

Our main focus was to make sure people got value fast and easily. Once we started doing that, our SEO improved. I think Google monitors how much time people spend on each page it recommends.

If your users are spending an average of 2 minutes, you are gold.

    This is an impressive case study, Shashank! 👏 Hitting $5,000+ MRR entirely through organic growth shows the power of SEO, user experience, and value-first design. I love how you structured API.market like an e-commerce platform and made every API instantly usable via the playground—it’s a smart way to keep developers engaged.

    The focus on measuring real user behavior (like time on page) and iterating based on insights is a great reminder that product usability drives SEO and growth. Thanks for sharing such actionable strategies—especially the combination of daily content, backlinks, and detailed analytics. Definitely inspiring for other indie makers!
