Case Study: Xandar Mob earns 15% of revenue and achieves 95% fill rate with Google AdMob

Indie game developer turns a hobby into income with AdMob

Xandar Mob is an independent studio run by William Ferguson and creator of Lexathon, a 4.5‑star word‑puzzle game on Google Play with more than 500,000 downloads and a loyal player base. Facing the challenge of turning his hobby into sustainable income while keeping the app free and global, Ferguson turned to Google AdMob to monetize Lexathon without harming the user experience.

Using Google AdMob’s SDK and mediation, Ferguson implemented banner and interstitial ads, created custom events to integrate multiple ad networks, and offered an ad‑free purchase option. Google AdMob’s mediation delivered a 95% fill rate and reliable CPMs, and AdMob now generates about 15% of Xandar Mob’s income, helping Ferguson pay down loans and grow his user community.
