We're making a change to how we report ad requests in Multiplex ads. Currently, ads in a Multiplex ad unit are counted as one ad request with multiple impressions for each slot within the grid. Starting June 23, 2026, we will report every ad in the grid as its own ad request.
This change will result in an increase in the number of ad requests for your Multiplex ads units. You should expect a shift in metrics related to ad requests, such as ad requests, matched ad requests, ad request CTR, and coverage. You will likely not see a significant change in total impressions and revenue.
