Microsoft is testing a new UI feature in Bing Search that expands favicons when users hover their cursor over a search listing or ad.

This interactive effect applies to both organic results and paid ads, aiming to draw more attention to individual listings.
While the change is purely visual and doesn’t impact ad placement or ranking, it could subtly improve engagement and click-through rates by emphasizing brand identity.
The feature is currently visible to a limited number of users as part of a live test. See it in action here:
