How this was measured
Measured by Roentgen 1.27.0 on 2026-09-17. 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 1,781 multi-step funnels, more conversion tactics than 88% 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.
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 15 measured checks need work
Text contrast (WCAG AA)
contrast:90% of measurable text passes WCAG AA. 4+ runs fail. 34% of text was unmeasurable (over images/gradients). not counted either way.
worst: “Product Member” at 1.97:1 (11px, #b7b8c2 on #ffffff). 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 1.13×, tight enough to hurt readability.
FixSet body line-height to ~1.4-1.6×.
Named controls
a11y:8 buttons/links have no accessible name (icon-only, no aria-label).
FixAdd aria-label to icon-only buttons and links.
Page weight
weight:At least 14.2 MB across 399 measurable resources. 276 cross-origin resources did not expose a size, so the real total is higher.
FixCompress and lazy-load below-the-fold media; drop unused third-party scripts.
Render-blocking resources
weight:57 stylesheets/scripts in <head> block first paint.
FixDefer non-critical JS (defer/async) and inline only critical CSS.
Oversized images
weight:14 images are shipped at more than 2x the width shown.
“kernel.0j8z0plp65loq.svg” is 837px wide, displayed at 126px
FixServe responsive sizes (srcset/sizes) matching the rendered width.
Worth knowing5
Line length
3 paragraphs run past ~95 characters per line.
FixCap measure at ~60-75ch for comfortable reading.
type:Heading structure
The landing page has 6 <h1> elements (expected 1).
FixUse exactly one <h1> as the page’s title.
a11y:Heading levels
1 heading skips 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:Label in name
2 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:Landmark regions
No <main> landmark. screen-reader users cannot jump between regions.
FixWrap the page in <header>, <main> and <footer> (or matching ARIA roles).

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