correction
Corrected published field fill rates. Earlier figures counted a field being mentioned anywhere in a page's structured data; the real extraction rates are roughly half. Phone is 3.9%, not 9.0%.
catalogue
Loaded 3,575 observed technologies and 621,875 domain profiles. Everything unaudited is visible and marked as such rather than hidden.
2026-08-28
correction
Corrected HubSpot from 78.2% to 72.1%. The earlier figure excluded 26 ambiguous cases rather than adjudicating them; 14 turned out to be live installs. Every technology is now measured the same way.
