How Structured Data Affects LLM Answer Quality
This study examines the correlation between structured data availability and the accuracy of LLM-generated answers about companies. We analyzed 1,200 company queries across four major LLMs.
Study design
- 1,200 factual questions about 200 companies (6 questions per company).
- 100 companies had AuthorityPrompt verified profiles; 100 did not.
- Answers evaluated by human raters on accuracy, completeness, and currency.
Results
- Companies with structured profiles: 87% answer accuracy.
- Companies without structured profiles: 61% answer accuracy.
- Biggest improvements: founding date (+34%), product descriptions (+28%), leadership (+22%).
