Maximising Interstitial Ad Revenue: Technical Insights
Successful ad monetization requires strategic implementation beyond simply selecting a network. I maintain 4-6 second display frequency caps to prevent user fatigue, whilst testing placement timing extensively to identify optimal transition points in the online advertising industry.
A/B testing reveals that interstitials displaying after content consumption generate 40-50% higher engagement than those appearing during active usage. I recommend implementing analytics tracking to measure user retention rates pre and post-interstitial implementation.
Combining multiple networks through mediation platforms and ad exchange typically increases overall eCPMs by 15-25% compared to single-network strategies. However, manage integration complexity carefully—excessive SDK bloat degrades app performance and user experience. Consider using support resources and checking compatibility with Android Gradle plugin.
