60/100 Partial

Scores higher than 66% of 1,391 multi-step funnels we have measured. Among the 1,074 saas funnels in that group, higher than 58%.

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 60 · mobile 60.

Walk 40 links on the entry page, 21 walkable. 4 matched a funnel step; we captured 4 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.

contrast, mobile, typography, accessibility, weight — each with what would fix it

measuredextracted directly from the live page. a fact, not an opinion

5 of 15 measured checks need work1 could not be measured — not counted either way

Text contrast (WCAG AA)

contrast:text-contrast-wcag-aa

93% of measurable text passes WCAG AA. 4+ runs fail.

worst: “presigned ≤ 25MB” at 1.1:1 (12px, #ffffff on #f1f5f9). needs 4.5:1

FixRaise text/background contrast to ≥4.5:1 (≥3:1 for large text), especially on CTAs and body copy.

Body text size

type:body-text-size

Smallest body text is 9px (base ~14px). below the ~16px readable floor.

FixKeep body copy ≥15-16px; reserve sub-13px for fine print only.

Named controls

a11y:named-controls

4 buttons/links have no accessible name (icon-only, no aria-label).

FixAdd aria-label to icon-only buttons and links.

Oversized images

weight:oversized-images

10 images are shipped at more than 2x the width shown.

“logo-light.svg” is 450px wide, displayed at 111px

FixServe responsive sizes (srcset/sizes) matching the rendered width.

Tap-target size (mobile)

mobile:tap-target-size-mobile

249 of 320 interactive targets are under 44×44px on mobile.

smallest: “Dismiss and decline analytics” at 24×24px

FixGive tappable controls a ≥44×44px hit area. the touch minimum.

Worth knowing6

Line length

19 paragraphs run past ~95 characters per line.

FixCap measure at ~60-75ch for comfortable reading.

type:line-length
Heading levels

2 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:heading-levels
Render-blocking resources

7 stylesheets/scripts in <head> block first paint.

FixDefer non-critical JS (defer/async) and inline only critical CSS.

weight:render-blocking-resources
Autocomplete hints

No autocomplete attributes across 4 fields. browsers cannot autofill.

FixAdd autocomplete="email"/"tel"/"name" to identity fields.

Page weight

At least 3.8 MB across 144 measurable resources, but 180 cross-origin resources did not expose a size. The true weight cannot be determined from the page.

Playbook match — which funnel play this page runs — measured, evidence-quoted

We ran this pass 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.
