In May 2026, AI search assistants significantly increased their reliance on consumer reviews to answer user queries. ChatGPT cited reviews in nearly 30 percent of its responses during that period.
Why it matters
The heavy reliance on user-generated content highlights how search algorithms prioritize proximity to purchase decisions. These systems now weigh consumer feedback alongside traditional news publisher data when crafting responses.
In May 2026, reviews comprised 28.9 percent of all ChatGPT citations, while Google AI Mode sourced 19.9 percent of its citations from similar content. Travel-related prompts saw these figures spike, with reviews making up over 50 percent of citations.
The players
ChatGPT
ChatGPT is an artificial intelligence chatbot developed by OpenAI that uses large language models to generate text responses.
Google AI Mode
Google AI Mode is an experimental search feature that utilizes generative artificial intelligence to provide direct, synthesized answers to queries.
The details
AI systems select sources by analyzing the closeness of user-generated content to an active purchase intent. By blending this feedback with standard news publisher data, the models aim to provide more localized and practical information for shoppers.

The Tech Race
This strategy follows the historical integration of user-generated content into algorithmic ranking systems. It marks a shift where AI models move beyond static databases to favor real-time social feedback, intensifying the competition between AI providers to deliver the most practical shopping data.
Users should recognize that AI-generated summaries may prioritize consumer sentiment over expert or journalist analysis when searching for products. This can lead to more subjective, review-based responses that might exclude objective performance metrics.
The takeaway
When using AI for shopping, verify review-based claims against professional testing sources to ensure accuracy. Relying solely on AI summaries may inadvertently highlight outliers in consumer experiences rather than broader trends.
