I Make $15K/Month From One Website
Maddox, a college student, built DuckMath (duckmath.org), an unblocked games website monetized with Google AdSense. It sat mostly idle for ~2 years until a surprise $240 day pushed him to go all in on marketing: 3 TikTok accounts posting 3x a day, 5 days a week, copying competitors' best formats and cross-posting to Reels, Shorts and Snapchat. In ~4 months it went to 150,000 daily active users and ~$15K/month, then he sold it to a bigger game-site company for $120K after countering a $100K offer.
