85/100 Strong
Scores above 95% of 1,252 multi-step funnels we have measured. Among the 959 saas funnels in that group, above 94%.
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 106 links seen, 78 walkable, 3 matched, and we walked 4 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
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 & contrastclear
Text contrast (WCAG AA) passescontrast:text-contrast-wcag-aa
100% of measurable text passes WCAG AA. 98% of text was unmeasurable (over images/gradients). not counted either way.
Mobile & tap targetsclear
Mobile viewport passesmobile:mobile-viewport
Responsive viewport meta is present.
Typography1 flagged
Body text size needs worktype:body-text-size
Line length notetype:line-length
29 paragraphs run past ~95 characters per line.
fix Cap measure at ~60-75ch for comfortable reading.
Accessibility hygiene1 flagged
Language declared passesa11y:language-declared
html[lang] is set for screen readers.
Image alt text passesa11y:image-alt-text
All 44 content images carry alt text.
Named controls needs worka11y:named-controls
5 buttons/links have no accessible name (icon-only, no aria-label).
fix Add aria-label to icon-only buttons and links.
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 noteweight:page-weight
At least 3.7 MB across 827 measurable resources. 28 cross-origin resources did not expose a size, so the real total is higher.
fix Compress and lazy-load below-the-fold media; drop unused third-party scripts.
Render-blocking resources noteweight:render-blocking-resources
4 stylesheets/scripts in <head> block first paint.
fix Defer non-critical JS (defer/async) and inline only critical CSS.
Oversized images needs workweight:oversized-images
24 images are shipped at more than 2x the width shown.
“overview-light.webp” is 5600px wide, displayed at 946px
fix Serve responsive sizes (srcset/sizes) matching the rendered width.
Structure & reachabilityclear
Landmark regions notestructure:landmark-regions
No <header> landmark. screen-reader users cannot jump between regions.
fix Wrap the page in <header>, <main> and <footer> (or matching ARIA roles).

OpenPanel Analytics | An open-source alternative to Mixpanel
A match means this funnel's measurable surfaces fit the playbook's pattern — the quoted language is what fired the detection. A lever is one playbook mechanism observed on-page. We never claim what a brand's ads or emails do; a crawl can't see them. All funnel designs →
Two different things sit side by side here. The claim and its quoted evidence are measured on this funnel, the same way every other fact on this page is. The playbook itself is written guidance — our strategy library, not a measurement of this site — and it lives behind the links above. Nothing on this page recommends what this brand should do.
