Should you prioritize llms.txt over answer infrastructure? | Trakkr Research
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 |

| 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.
What to do next
- Treat llms.txt as an optional housekeeping file rather than a primary citation-growth lever.
- Prioritize answer quality, source coverage, and page structure before spending disproportionate effort on llms.txt.
- Measure discovery and crawl behavior directly if you publish llms.txt instead of assuming it improved citation performance.
