Google Merchant Center briefly displayed internal AI prompts intended for generating performance insights, rather than just the final summaries.
The glitch exposed behind-the-scenes parameters like click changes for 20 products and decision rules for highlighting top items. Users saw instructions such as “thinking” and “Formatting” normally hidden in AI processing. Google’s accidental reveal didn’t leak sensitive data but provided an amusing look at the technology generating performance summaries.
