I built a passive income gaming site in 7 days using AI — here's the exact workflow

#webdev #gamedev #ai

Last week I sat down with Cursor, a domain registrar, and a very specific niche keyword. Seven days later, the site was live, indexed, and earning its first AdSense impressions.
No team. No boilerplate repo I'd spent weeks perfecting. Just a clear prompt, an AI that could actually build what I described, and a keyword gap that nobody had filled yet.
Here's the part that surprised me most: the hardest part wasn't the code. Cursor handled the frontend. Claude Code handled the backend logic. GitHub Copilot filled in the gaps inline. The hard part was the judgment call — picking the right game, the right tool type, and the right search query that sits in that sweet spot of high intent and low competition.
The gaming niche looks saturated on the surface. It isn't. IGN and GameSpot own "best games 2026." Nobody owns "nicheRPGniche RPGnicheRPG damage calculator after patch 4.1." That's where a focused tool site walks in and ranks on page one within weeks.
The monetization side is equally concrete. Gaming sites on AdSense typically earn $3–$10 RPM. At 50k monthly pageviews from US/UK traffic, that's $300–$800/month passively. Hit 50k sessions and you can graduate to Mediavine for another 20–70% on top. It's not "get rich quick" math — it's compounding, predictable, and entirely driven by whether you picked the right keyword in week one.

    ul { list-style-type: disc; }
    ul ul { list-style-type: circle; }
    ul ul ul { list-style-type: square; }
