AI-generated snippets on Google SERPS are confirmed to be an experiment, not a definite feature. They not labeled as AI-generated in desktop results, but that should change.

• First, Brodie Clark posted about AI-generated search snippets not being labeled as such.
• Then, Barry Schwartz confirmed by showing the same exact snippet has the "Gemini sparkle" icon next to it on mobile SERPs but not on desktop.
• Finally, Rajan Patel responded: "It's both an experiment we haven't launched yet (and not sure we'll launch it) and a bug we'll fix to make it look more like what you see on mobile."
