Scores higher than 63% of 1,391 multi-step funnels we have measured. Among the 1,074 saas funnels in that group, higher than 55%.
How this was measured
Measured by Roentgen 1.25.1 on 2026-08-15. 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 55 · mobile 70.
Walk 167 links on the entry page, 118 walkable. 2 matched a funnel step; we captured 3 pages in all, this one included.

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.
How well it’s built
14 run · 5 flaggedcontrast, mobile, typography, accessibility, weight — each with what would fix it
measuredextracted directly from the live page. a fact, not an opinion5 of 13 measured checks need work1 could not be measured — not counted either way
Text contrast (WCAG AA)
contrast:94% of measurable text passes WCAG AA. 4+ runs fail.
worst: “✶✶✶✶✶✶✶✶ ✶✶✶✶✶✶✶✶” at 2.29:1 (12px, #ff8800 on #fafafa). needs 4.5:1
FixRaise text/background contrast to ≥4.5:1 (≥3:1 for large text), especially on CTAs and body copy.
Named controls
a11y:16 buttons/links have no accessible name (icon-only, no aria-label).
FixAdd aria-label to icon-only buttons and links.
Landmark regions
structure:No <main> or <footer> or <header> landmark. screen-reader users cannot jump between regions.
FixWrap the page in <header>, <main> and <footer> (or matching ARIA roles).
Tap-target size (mobile)
mobile:92 of 120 interactive targets are under 44×44px on mobile.
smallest: “Show password” at 16×16px
FixGive tappable controls a ≥44×44px hit area. the touch minimum.
Worth knowing5
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:Link text
1 link uses generic text (“click here” / “learn more”).
FixMake link text describe its destination out of context.
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:Label in name
8 controls have an aria-label that does not contain its visible text, so voice-control users cannot activate it by saying what they see.
FixMake the accessible name start with the visible label text.
a11y:Keyboard reachability
15 elements look clickable but cannot be reached by keyboard.
FixUse <button>/<a>, or add role + tabindex="0" and a key handler.

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.
