Case Study: Eltsoft achieves 20x revenue growth with Google AdMob interstitials

Eltsoft increases revenue 20x using AdMob interstitials

Eltsoft, a mobile language-learning app developer best known for English Grammar (over one million downloads), needed a simple way to monetize free app versions while delivering localized, language-relevant ads worldwide. The company turned to Google AdMob, initially running banner ads and then adding interstitial text, image, and video formats to reach its global user base.

Using Google AdMob’s rich-media interstitials and leveraging Google Analytics for campaign and localization insights, Eltsoft saw revenue jump dramatically—generating 10–20× more income overnight and up to a 20-fold increase overall. The AdMob solution also improved campaign analysis and user experience through better targeting, and Eltsoft is expanding into video ads and further AdMob features to sustain growth.
