We found more conversion tactics here than on 66% of the 324 entry-page SaaS captures we have measured.
4 conversion tactics detected
1 page walked · measured by Roentgen 1.27.0
Walk 3 links seen, 1 walkable, and 0 matched a funnel step. If this funnel continues past the entry page, we did not reach it — everything below is measured from the entry page alone.
How this was measured
Measured by Roentgen 1.27.0 on 2026-09-11. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.
This is detection coverage, not a verdict — it counts the conversion tactics we could prove are present, out of the 11 that apply to a saas funnel. A low count means we did not detect those patterns, not that the funnel is weak.
Against all 640 entry-page captures, more conversion tactics than 79% of them.

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 ran these passes on the pages we captured and found nothing to show. That is a measurement of this funnel, not a recommendation — and it is a different statement from a layer we never ran, which does not appear here at all.
