Google Ads is testing a subtle design update affecting brand logos. As observed by Adriaan Dekker and Arpan Banerjee, a grey container now surrounds some logos in mobile ad placements.

This visual tweak doesn’t alter the logo itself but changes how it’s framed, potentially drawing more attention. So far, it appears on select mobile search results and may not be visible to all users.
Google has not issued an official statement regarding this UI change, and it’s unclear whether this is a limited experiment or a broader rollout.
