60/100 Partial
Scores higher than 94% of 577 entry-page captures we have measured. Among the 311 saas funnels in that group, higher than 92%.
Walk 4 links seen on the entry page, and none were walkable past it. We only follow a[href], so a funnel behind a button or a login would not appear here.
How this was measured
Measured by Roentgen 1.27.0 on 2026-09-03. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.
Coverage 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. Per device: desktop 60 · mobile 60.

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.

Form labels
1 form field relies on placeholder text as the only label.
FixBack placeholders with a real <label>. placeholder text vanishes on input.
a11y:Skip link
No same-page “skip to content” link was found. Keyboard users tab through the whole nav on every page.
FixAdd a first-in-DOM <a href="#main"> that is visible on focus.
a11y:Autocomplete hints
No autocomplete attributes across 1 field. browsers cannot autofill.

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.
