We found more conversion tactics here than on 10% of the 1,450 multi-step SaaS funnels we have measured.
3 pages walked · measured by Roentgen 1.29.0
Every figure on this page was read off the live site by Roentgen 1.29.0 on 2026-10-15, a script that reads page structure, computed CSS and matched text. No AI judgment, nothing estimated, and a capture’s numbers stay as read.
Detection coverage, not a verdict. A low count means we did not detect those patterns, not that the funnel is weak.

Absence is a measurement, not a recommendation: we do not know why a tactic is missing, whether it belongs here, or whether adding it would change anything. Where a walk stopped early, a tactic living deeper would also read as not detected.
