Methodology and limits

Each report contains 66 live runs: six runs for each of 11 personas. Each response contributed a ranked top 10, producing 660 ranked positions per industry.

  • The scope includes only domains recommended at least once. It does not include a control group of non-recommended domains.
  • No multiple-comparison correction or confidence intervals were calculated.
  • Observations across signals are not independent, and the ten SEO signals are collinear.
  • A zero can record absence in the Ahrefs export; it is not proof that no real-world activity exists.
  • The persona panels are small. Exactly 23/33 panels have n<20 and are exploratory.
  • This is the complete aggregated recommended-domain dataset for this sample, not a complete or auditable web-wide dataset.
