10/100 Sparse
Scores above 24% of 525 entry-page captures we have measured. Among the 289 saas funnels in that group, above 5%.
Walk 0 links seen on the entry page, and none were walkable past it. We only follow a[href], so a funnel behind a button or a login would not appear here.
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.

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
12 run · 3 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
93% of measurable text passes WCAG AA. 4+ runs fail.
worst: “⎇ master” at 2.15:1 (10px, #5d5e5f on #2c2c2d). 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.
Typography1 flagged
Body text size needs worktype:body-text-size
Accessibility hygieneclear
Language declared passesa11y:language-declared
html[lang] is set for screen readers.
Heading levels notea11y:heading-levels
2 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.
Label in name notea11y:label-in-name
1 control has an aria-label that does not contain its visible text, so voice-control users cannot activate it by saying what they see.
fix Make the accessible name start with the visible label text.
Weight & deliveryclear
Page weight not measurableweight:page-weight
At least 0.1 MB across 5 measurable resources, but 3 cross-origin resources did not expose a size. The true weight cannot be determined from the page.
Render-blocking resources passesweight:render-blocking-resources
1 stylesheet/script in <head> block first paint.
fix Defer non-critical JS (defer/async) and inline only critical CSS.
Oversized images noteweight:oversized-images
2 images are shipped at more than 2x the width shown.
“logo.png” is 256px wide, displayed at 22px
fix Serve responsive sizes (srcset/sizes) matching the rendered width.
Structure & reachability1 flagged
Landmark regions needs workstructure:landmark-regions
No <main> or <header> landmark. screen-reader users cannot jump between regions.
fix Wrap the page in <header>, <main> and <footer> (or matching ARIA roles).
Keyboard reachability notestructure:keyboard-reachability
19 elements look clickable but cannot be reached by keyboard.
“mux0 ⎇ master”, “mux0”, “⎇ master”
fix Use <button>/<a>, or add role + tabindex="0" and a key handler.
