Ad Placement Strategy 📊

Ad Type	Recommended Placement	Frequency & Usage	Why It Matters
Banner	Bottom/Top of screens	Persistent visibility	Non-intrusive, maintains user flow while generating steady impressions
Interstitial	Between natural breaks (e.g., level completion)	1-2 times per screen transition	Avoids interrupting critical user journeys while maximizing impact
Native	Blended with content feeds	Every 5-6 content items (e.g., after 5 news articles)	Feels organic - users perceive ads as natural content
Rewarded	Optional rewards section	User-initiated (only when users choose rewards)	Higher completion rates since users actively opt-in
App Open	App launch/return from background	Limited to 3 times/day (even with 10+ app opens)	Prevents ad fatigue from frequent app usage
