AdMob’s large banner APIs require a layout check
A new sizing interface is a reason to inspect the playable game screen, not assume a revenue gain.
A banner-sizing migration changes a product surface that players can see. The useful release question is whether the chosen placement still respects the game’s controls and layout under the conditions the team supports.
Review the placement in context
Our recommendation is to test the actual screen around the banner, including orientation changes and transitions into or out of gameplay. A banner displayed correctly in an isolated sample is weaker evidence than the same integration exercised inside the game’s normal navigation.
Record the available space, the requested size and the observed result. If the game reserves space before loading, inspect both the empty and filled states. The objective is a stable, understandable interface rather than a screenshot containing an ad somewhere on the screen.
Keep monetisation hypotheses testable
Google’s migration guide documents the replacement interface. It does not supply an independently verified improvement for your title. Any claim that a larger placement increases net value should account for player behaviour, opportunity cost and the rest of the monetisation mix.
The change card is designed for an engineering-to-growth handoff: which build adopted the method, where the placement appears and which layouts were checked. It leaves revenue effects unmeasured. That separation allows a later experiment to investigate value without treating an API upgrade as its own commercial justification.
