Google changes AdSense Multiplex ad request counting to per-slot basis, inflating volumes without affecting revenue

Summary

Google changed how it counts ad requests inside Multiplex ad units on June 23, 2026, moving from a single consolidated request per grid to one individual request per slot. This shift causes a visible jump in ad request volumes for publishers using the format, but does not change underlying revenue. The update alters a counting convention that has been in place since Multiplex ads launched. Under the previous system, an entire Multiplex grid generated one ad request; now each slot generates its own. Coverage and request click-through rates will shift as a result, but total revenue should remain unaffected.
