Does an llms.txt file predict higher AI visibility?
hypothesis + method published before the result.
Hypothesis
Sites that publish an llms.txt file achieve a materially higher SAVI (AI Visibility Index) than sites without one.
Method
Segment the 850k corpus by llms.txt presence; compute mean SAVI for each segment with a 95% confidence interval; report the between-group delta and whether it is significant. Pre-registered before the query is run — the result publishes regardless of direction (including null).
Dataset
850k+ audit corpus (metric: no_llms_txt — currently 69.7% have none).
Metrics
| SAVI delta (llms.txt vs none) | measure with 95% CI |
| significance | report regardless of direction |
Result
Pending — pre-registered; the result will be published here.
Decision
REGISTERED. Correlational; a positive result motivates a controlled follow-up (does ADDING llms.txt raise SAVI). No causal claim from this alone.
