About this Lab

This public monitoring dashboard repeatedly asks the same questions to observe which electronics retailers and e-commerce sites generative AI presents as places to buy, then publishes mechanically aggregated results.

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.

Updates

Data is added after each observation and accumulated as a daily trend. Last updated is the time of the latest aggregation.

Product and service names are trademarks or registered trademarks of their respective owners.
