20/100 Sparse
Scores higher than 9% of 1,391 multi-step funnels we have measured. Among the 1,074 saas funnels in that group, higher than 4%.
How this was measured
Measured by Roentgen 1.20.1 on 2026-08-09. 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 20 · mobile 20.
Walk 83 links on the entry page, 58 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
15 run · 7 flaggedcontrast, mobile, typography, accessibility, weight — each with what would fix it
measuredextracted directly from the live page. a fact, not an opinion7 of 14 measured checks need work1 could not be measured — not counted either way
Text contrast (WCAG AA)
contrast:85% of measurable text passes WCAG AA. 4+ runs fail.
worst: “1.18.0” at 3.56:1 (11px, #ffffff on #e9573f). needs 4.5:1
FixRaise text/background contrast to ≥4.5:1 (≥3:1 for large text), especially on CTAs and body copy.
Line height
type:Body line-height is 1×. tight enough to hurt readability.
FixSet body line-height to ~1.4-1.6×.
Named controls
a11y:64 buttons/links have no accessible name (icon-only, no aria-label).
FixAdd aria-label to icon-only buttons and links.
Oversized images
weight:23 images are shipped at more than 2x the width shown.
“svg+xml,%3Csvg%20display%3D%22block%22%2” is 150px wide, displayed at 20px
FixServe responsive sizes (srcset/sizes) matching the rendered width.
Landmark regions
structure:No <header> or <main> 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:166 of 169 interactive targets are under 44×44px on mobile.
smallest: “SDKs” at 40×22px
FixGive tappable controls a ≥44×44px hit area. the touch minimum.
Worth knowing3
Heading structure
The landing page has 3 <h1> elements (expected 1).
FixUse exactly one <h1> as the page’s title.
a11y:Heading levels
6 headings skip a level (e.g. <h2> followed by <h4>). Screen-reader users navigate by this outline.
FixStep heading levels one at a time; use CSS for size, not a deeper level.
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:Not measurable1
Page weight
At least 0.5 MB across 65 measurable resources, but 20 cross-origin resources did not expose a size. The true weight cannot be determined from the page.

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.
