Web browser game developers monetize primarily through in-game ads (interstitial, rewarded, banner), complemented by in-game purchases and portal revenue share. Ad revenue is governed by ad requests, fill rate, and eCPM. Studios either integrate ad SDKs or AdSense H5 Games Ads on self-hosted titles or monetize via distribution platforms.

|---|---|---|
| Revenue formula for ad monetization | requests x fill rate x eCPM/1000 | playgama.com |
| Full-screen ad formats vs banners | several times higher eCPM | playgama.com |
The dominant model is ad-based: interstitial, rewarded and banner ads shown at natural breaks in the game. Revenue is driven by three things – how many ad requests your game generates, what fraction get filled with an ad, and the eCPM of those impressions (revenue = ad requests x fill rate x eCPM / 1000). Full-screen formats like rewarded and interstitial typically earn several times more per impression than banners, and Tier-1 geos earn several times more than other geos, so format mix and audience matter more than raw traffic volume.
Playgama Ad connects one SDK to 11 demand partners, including Google Ad Manager; access is by application.
What are the main options?
- Google AdSense H5 Games Ads – apply for AdSense, add the code, and call the Ad Placement API (adBreak()) from your game code for interstitial and rewarded ads at pauses; runs on your own site or embedded elsewhere.
- Gaming-focused ad platforms – AdinPlay, Playwire and Venatus combine header bidding with direct demand aimed at game publishers; AppLixir focuses on rewarded video.
- Distribution portals – Poki, CrazyGames, GameDistribution, GamePix, Famobi, GameMonetize, itch.io and playgama.com host and distribute games, often with their own monetization built in.
- Hybrid: ads plus in-app purchases – many titles now add IAP or liveops events alongside ads as a second revenue stream, following mobile’s pattern.
Start by deciding whether you’ll self-host (needed for AdSense/direct SDKs) or publish through a portal, then match ad format mix to your session length.
