Google is testing different ways of displaying website identifiers in ads within AI Mode on mobile.
Some ads show the advertiser’s website name, while others display the website URL instead. Both formats have also been spotted appearing together within the same AI Mode experience.

It’s unclear which format is newer or whether Google plans to standardize how advertiser websites are displayed. However, this visual difference could influence how users recognize brands and identify advertisers in AI Mode.
