No. The null citation result means llms.txt should sit behind answer-first content, source coverage, and better page structure in the priority stack.

## Methodology

Built from HTTP scans of 37,894 AI-cited domains, linked to 337,362 citations and 882 citation snapshots in the Trakkr corpus.

## Direct Answer

No. The null citation result means llms.txt should sit behind answer-first content, source coverage, and better page structure in the priority stack.

## What this means

This answer matters because it turns a study finding into an operating rule teams can use when they decide what to publish, refresh, or measure next, preventing misallocation of engineering resources based on a Mann-Whitney p-value of 0.85.

## Evidence table

| Metric | Value | Why it matters |
| --- | --- | --- |
| Mann-Whitney p-value | 0.85 | No statistically significant citation effect detected. |
| Average citations with llms.txt | 6.8 | Mean citations for domains with llms.txt. |
| Average citations without llms.txt | 6.7 | Mean citations for domains without llms.txt. |

## Frequently Asked Questions

### Does adding an llms.txt file increase our average citations?

No statistically significant citation effect was detected. Domains with the file averaged 6.8 citations, while domains without it averaged 6.7 citations.

### Is the difference in citations statistically significant?

No. The Mann-Whitney p-value is 0.85, indicating no statistically significant citation effect detected.
