20/100 Sparse
Scores above 9% of 1,252 multi-step funnels we have measured. Among the 959 saas funnels in that group, above 3%.
How this was measured
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.
Measured by Roentgen 1.20.1, one of our versioned rulesets. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.
Walk 83 links seen, 58 walkable, 2 matched, and we walked 3 pages.

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 · 6 flaggedcontrast, mobile, typography, accessibility, weight — each with what would fix it
measuredextracted directly from the live page. a fact, not an opinionReadability & contrast1 flagged
Text contrast (WCAG AA) needs workcontrast:text-contrast-wcag-aa
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
fix Raise text/background contrast to ≥4.5:1 (≥3:1 for large text), especially on CTAs and body copy.
Mobile & tap targetsclear
Mobile viewport passesmobile:mobile-viewport
Responsive viewport meta is present.
Typography2 flagged
Body text size needs worktype:body-text-size
Line height needs worktype:line-height
Body line-height is 1×. tight enough to hurt readability.
fix Set body line-height to ~1.4-1.6×.
Accessibility hygiene1 flagged
Language declared passesa11y:language-declared
html[lang] is set for screen readers.
Image alt text passesa11y:image-alt-text
All 59 content images carry alt text.
Named controls needs worka11y:named-controls
64 buttons/links have no accessible name (icon-only, no aria-label).
fix Add aria-label to icon-only buttons and links.
Heading structure notea11y:heading-structure
The landing page has 3 <h1> elements (expected 1).
fix Use exactly one <h1> as the page’s title.
Heading levels notea11y:heading-levels
6 headings skip a level (e.g. <h2> followed by <h4>). Screen-reader users navigate by this outline.
fix Step heading levels one at a time; use CSS for size, not a deeper level.
Skip link notea11y:skip-link
No same-page “skip to content” link was found. Keyboard users tab through the whole nav on every page.
fix Add a first-in-DOM <a href="#main"> that is visible on focus.
Weight & delivery1 flagged
Page weight not measurableweight: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.
Oversized images needs workweight:oversized-images
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
fix Serve responsive sizes (srcset/sizes) matching the rendered width.
Structure & reachability1 flagged
Landmark regions needs workstructure:landmark-regions
No <header> or <main> landmark. screen-reader users cannot jump between regions.
fix Wrap the page in <header>, <main> and <footer> (or matching ARIA roles).
Form usabilityclear
Inline validation passesforms:inline-validation
1 field carries validation attributes (required/pattern/aria-invalid).
