30/100 Sparse
Scores above 18% of 1,252 multi-step funnels we have measured. Among the 959 saas funnels in that group, above 10%.
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 1.25.1, 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 38 links seen, 27 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

measuredextracted directly from the live page. a fact, not an opinionReadability & contrast1 flagged
Text contrast (WCAG AA) needs workcontrast:text-contrast-wcag-aa
65% of measurable text passes WCAG AA. 4+ runs fail.
worst: “mcpvault.io/servers” at 2.75:1 (12px, #8a8f8c on #e9ebea). 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 targets1 flagged

Responsive viewport meta is present.
Tap-target size (mobile) needs workmobile:tap-target-size-mobile
80 of 90 interactive targets are under 44×44px on mobile.

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.
