There is no universal ‘good’ viewability number for browser games because it depends on ad format, placement and device mix. Full-screen formats shown at natural pauses typically score highest; small banners placed below the fold score lowest. Judge it against your own game’s baseline, not an external benchmark.

There’s no fixed ‘good’ viewability rate for browser games – no ad network or standards body publishes a neutral benchmark for web games specifically, so treat any number you see quoted elsewhere with caution. What matters is comparing your own placements against each other over time, not chasing an external target.
If you want this tracked without building your own reporting, Playgama Ad reports fill rate, show rate, eCPM and revenue broken down by placement, format, geo and device, so you can see which placements are actually being seen and adjust from there.
Viewability sits upstream of your revenue metrics: ad requests lead to a match, then a fill, then an impression – and viewability tells you whether that impression was actually seen on screen, not just technically served. A full-screen interstitial or rewarded ad shown at a natural pause is almost always seen in full; a banner placed below the fold or behind game UI may register an impression while barely being visible. That gap is why full-screen formats tend to earn several times more per impression than banners, and why swapping placement matters more than tweaking any single setting. Revenue is calculated as Revenue = ad requests x fill rate x eCPM / 1000. In relative terms, full-screen formats earn several times more per impression than banners, and Tier-1 geos earn several times more than other geos.
What actually moves viewability?
- Format: full-screen interstitial and rewarded placements score higher than banners by design.
- Placement timing: ads called at natural breaks (menu, level end, pause) are seen; ads squeezed mid-action or stacked back-to-back are often skipped or scrolled past.
- Device and layout: banners that get pushed off-screen on smaller viewports drag the average down.
Next step: pull your own fill and show rate by placement, isolate the weakest one, and test moving it to a natural pause point before comparing again.

Is viewability the same as fill rate?
No. Fill rate is impressions divided by ad requests; viewability asks whether an impression that was served was actually visible on screen to the player.
Does viewability affect eCPM?
Yes indirectly – buyers pay more for inventory with strong viewability, so improving placement visibility can lift eCPM over time even without changing demand partners.
