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 1.27.0
Every figure on this page was read off the live site by Roentgen 1.27.0 on 2026-09-09, 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.
paperlab.r3actr.work shows 3 of the 11 tactics that apply to a SaaS funnel, and we did not see the other 8.

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.
We walked 3 pages. 2 pages tie for the most named tactics (3), and Features runs none.

Body copy in their text role, on a surface card.
We also ran these layers on the pages we captured and found nothing to show: Elements, Playbook match (2 of 9 layers). That is a measurement of this funnel, not a recommendation, and a layer we never ran is not listed.
