ChatGPT gets the headlines, but Google gets the audience. Emarketer estimates that 187.4 million Americans see Google's AI Overviews every month.
Looking at that, I’d start my optimization efforts in the Google universe. So to some extent not a lot has actually changed in digital marketing. Win Google, win the rest.
By the Numbers:
1️⃣ 187.4M: estimated US monthly audience for Google AI Overviews 2️⃣ 117.4M: estimated US monthly users of Google Gemini and AI Mode combined 3️⃣ 60% of US adults had read an AI search summary as of February 2026 (Pew Research Center) 4️⃣ 71% of Google Search users see AI Overviews in a given month, about 55% of the US population 5️⃣ 60B+ product listings in Google's Shopping Graph
For merchants this matters. Google already owns the place where most shopping journeys start, and now it is adding AI answers and a cart. You should treat your product data on Google like your PDP. Remember: Your product feed is your sales pitch.
