Google AI Mode displays higher product prices than traditional search, study finds
A Productrise study tracking 2 million listings found matched items were an average of 21.6% more expensive in AI Mode.
The short version
- A study by Productrise found that identical products displayed in Google AI Mode were on average 21.6% more expensive than those in traditional search results.
- AI Mode offered a significantly smaller selection—averaging 3.9 items per query compared to 27.8 in traditional search—with only a 1.28% product overlap between interfaces.
- Online retailers and shoppers are affected as the AI tool frequently selects different merchants and surfaces higher-priced options as primary results.
- It remains unverified how Google's AI ranking criteria specifically select lead sellers and whether future algorithmic updates will alter pricing behavior.
