Analysis based on the latest observation data.
The Stella AI Search Lab is a retail-focused public research project that continuously observes how products and retailers are discovered and presented by AI as generative AI becomes a gateway to shopping. Rather than reducing the results to winners and losers, we aim to create a shared, transparent way for anyone to understand how the AI shopping landscape is changing.
Why We Publish This Research
Recommendations generated by AI are harder to inspect than conventional search rankings, and the same query can produce different answers. That is why we make our method and results as open as possible: so retailers, e-commerce businesses, manufacturers, site operators and shoppers can examine the same data and think about the changes together.
This dashboard does not claim to provide a single correct optimization strategy. By observing how AI understands and recommends products and points people to places to buy, it provides evidence for considering what information is getting through and what is still missing.
What You Can Learn Here
- Which retailers appeared across the widest range of queries
- Which retailers tended to appear near the top of answers
- How visibility differed by category and price range
- Which products, sources and retailers were connected in AI answers
What We Observe
We prepare fixed shopper personas and queries, then submit them through the ChatGPT web interface. We record the answer, citations and sources, product cards, and the retailer list for each product in the order shown.
How Rankings Are Calculated
Within each query, retailers are ranked using the following sequence.
- More products linked to that retailer in the answer
- If tied, the higher position in the retailer list
- If still tied, the greater number of retailer appearances
All rates use the number of successfully observed queries as their denominator.
- Coverage: share of queries where the retailer appeared at least once
- First-position rate: share of queries where the retailer ranked first
- Top 3 rate: share of queries where the retailer ranked in the top three
How to Read the Data
- Generative AI answers can change each time, even for the same query. A daily observation is a point-in-time snapshot, and a ranking change does not necessarily indicate the effect of an optimization measure.
- The current dataset covers ChatGPT only and does not represent other generative AI systems.
- Price, stock and delivery text is recorded as displayed in the AI answer and may differ from the retailer's actual selling conditions.
- Product and retailer naming variations are normalized, with normalization decisions retained in the source research records.
- This dashboard does not judge retailer quality or superiority; it records only how retailers appear in AI answers.
- When considering a purchase or contract, please verify prices, stock, specifications and other details on each company’s official website.
Independent Research
This site is independently planned and operated by Stellagent, Inc. Unless otherwise stated, the featured retailers and service providers did not commission the research, provide the data or supervise the content. Our priority is not to promote a particular company or judge businesses by rank alone, but to accumulate observed facts using a consistent standard.
Trademarks and Logos
Company names and logos help readers accurately identify which retailers appeared in an AI answer. We therefore use the company names, service names, trademarks and logos shown on this site only to the extent needed to identify observed retailers and explain the research results.
All rights in the respective trademarks and logos belong to their owners. Their appearance on this site does not indicate an affiliation with, endorsement by or approval from those rights holders. If you notice an issue with a name or published item, we will review it and respond in good faith.
Updates
Data is added after each observation and accumulated as a daily trend. Last updated is the time of the latest aggregation.
