All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The dark-mode screenshot is visually identical to the light capture, and the computed root color-scheme is normal with no prefers-color-scheme rule detected. F001 medium: The public site does not adapt its palette to a dark colour-scheme preference.
respect-user-preferences `respects-reduced-motion`	pass	high	Under prefers-reduced-motion: reduce, getAnimations() returned none and all seven autoplay videos were paused at time 0.
respect-user-preferences `respects-contrast`	pass	high	The forced-colors screenshot preserves visible text, borders, focusable actions, and hierarchy.
implement-natural-interactions `view-transitions`	issues	high	The CSS/DOM probe found no view-transition rules or API-backed transition styling, while the site exposes several route and carousel state changes. F002 low: Major state and route changes do not use View Transitions.
implement-natural-interactions `scroll-driven-animations`	pass	medium	The page uses ordinary document scrolling; the trace showed only two short long tasks and no scroll-linked jank during the captured path.
implement-natural-interactions `physical-gestures`	pass	medium	The mobile goals carousel exposes previous/next controls with accessible labels and a touch-sized visual treatment.
provide-guided-navigation `scroll-state-aware-chrome`	pass	high	Mobile captures show a persistent bottom Start now action while scrolled content remains unobstructed; desktop header leaves the viewport rather than consuming space.
provide-guided-navigation `anchored-positioning`	pass	medium	The mobile header/menu control and floating chat affordance remain within viewport edges in the narrow capture.
provide-guided-navigation `directs-attention`	pass	high	Across landing, goals, and support, one large H1 and a visually dominant next action establish an obvious reading and action sequence.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	Desktop and mobile screenshots show “Before you continue” instead of Google Ads content; on mobile the decision controls are below a long explanation and outside the first 800 px viewport. F011 medium: The requested ads.google.com entry point replaces the site with a full-page consent interruption.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	The DOM probe found nine DIV role=dialog surfaces and no native dialog or popover element on the landing page. F013 low: Overlay surfaces are implemented as custom div dialogs rather than native dialog/popover primitives.
maximize-content-reduce-noise `reduced-chrome`	pass	high	The first view is dominated by page purpose and CTA; navigation is compact on mobile and restrained on desktop.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	All five 360 px layout captures reported 0 px horizontal overflow.
adapt-to-the-form-factor `component-level-responsiveness`	pass	high	The same hero, goal card, navigation, and CTA surfaces recompose cleanly between 780 px and 360 px captures without clipping.
adapt-to-the-form-factor `input-modality-aware`	pass	high	The Start now CTA matched :focus-visible and rendered a 2 px contrasting focus box-shadow; mobile actions are approximately 50 px tall.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	Representative screenshots expose clear page-specific H1 copy and direct actions such as Start now, contact options, and goal navigation.
support-core-task-success `primary-flow-completion`	pass	high	Start now reaches a clearly branded Google Account sign-in page with an email/phone field; public support exposes call and contact-option actions.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The invalid-route test presents a specific 404 explanation plus Home, Expert Support, How It Works, Performance Max, and Search Ads recovery links.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse measured LCP 5.87 s, FCP 4.70 s, TBT 485.5 ms, CLS 0.074, and a performance score of 47. The separate trace was faster but still recorded two long tasks. F003 high: Mobile lab performance misses the good Core Web Vitals loading and responsiveness bar.
be-fast-and-stable `visual-stability`	pass	high	Mobile CLS was 0.027 in the layout observer and 0.074 in Lighthouse, both below the 0.1 good threshold.
be-fast-and-stable `efficient-main-thread`	issues	high	Lighthouse measured LCP 5.87 s, FCP 4.70 s, TBT 485.5 ms, CLS 0.074, and a performance score of 47. The separate trace was faster but still recorded two long tasks. F003 high: Mobile lab performance misses the good Core Web Vitals loading and responsiveness bar.
be-fast-and-stable `efficient-resource-delivery`	issues	high	The HAR captured 126 requests and 5.95 MB in its load window, including 2.27 MB fonts, 2.55 MB scripts, and 778 KB media. Lighthouse reported 50.7 MiB total payload, about 1.4 MiB unused JS and 193 KiB unused CSS. F004 high: The landing page ships an excessive script, font, media, and unused-code payload.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	The HAR captured 126 requests and 5.95 MB in its load window, including 2.27 MB fonts, 2.55 MB scripts, and 778 KB media. Lighthouse reported 50.7 MiB total payload, about 1.4 MiB unused JS and 193 KiB unused CSS. F004 high: The landing page ships an excessive script, font, media, and unused-code payload.
be-inclusive `names-roles-labels`	issues	high	Lighthouse identified four label-content-name mismatches, including visible “Generate more leads” and “Get started” links whose aria-label is “Sign up for Google Ads”, and the Expand all control. The image probe found 18 of 27 images without alt, including visible marketing imagery as well as product-logo assets. Decorative images should use alt=""; informative images need meaningful alternatives. F007 medium: Some visible control labels do not match their accessible names. F008 medium: Many images omit an alt attribute rather than declaring purpose.
be-inclusive `sufficient-contrast`	pass	high	Lighthouse accessibility scored 100 and the forced-colors capture retains readable controls and content.
be-inclusive `structure-and-focus`	pass	high	The page provides header/nav/main/footer landmarks, a skip link, one visible H1, and a visible focus treatment on the primary CTA.
be-inclusive `legible-text`	pass	high	Mobile captures use large headings, comfortable line length, and 16 px-class body copy without truncation.
be-inclusive `zoom-reflow-targets-and-media`	pass	high	The viewport allows maximum-scale=5, all mobile layouts reflow without overflow, primary targets are 50 px tall, and reduced-motion pauses autoplay media.
follow-best-practices `no-console-errors`	issues	high	Lighthouse captured a 401 console/network error from MeasurementService/ListAccounts during the ordinary signed-out landing load. F009 low: A signed-out page load logs a failed internal account request.
follow-best-practices `sound-document-and-assets`	pass	high	The rendered document has viewport metadata, dimensions on 26 of 27 images, responsive srcsets on visible marketing imagery, and low measured CLS.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse reported three bfcache failure reasons led by cache-control:no-store on the main resource and no-store resources requested by JavaScript. F015 low: The page is ineligible for the back/forward cache.
be-discoverable `title-and-description`	pass	high	All representative probes returned distinct, descriptive titles and descriptions aligned with their page purpose.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	Lighthouse SEO reported the Google Ads Help link with text “Learn more”, which is ambiguous out of context for crawlers and assistive navigation. F010 low: One public content link uses non-descriptive “Learn more” text.
be-discoverable `canonical-and-indexing-signals`	pass	high	The landing page has a UK canonical URL, HTTP 200, permissive /uk/ robots rule, and working sitemap URLs listed by robots.txt.
be-discoverable `structured-and-shareable-metadata`	issues	high	The UK page probe found JSON-LD WebPage @id/url and breadcrumb items under /us/, with a US title/description, while canonical and Open Graph URLs correctly identify /uk/. F012 medium: The UK page emits structured data for US URLs and US copy.
be-private-and-secure `secure-transport-and-headers`	pass	high	The page is HTTPS with HSTS, nosniff, SAMEORIGIN, Permissions-Policy and an enforced nonce/strict-dynamic CSP; the secrets scan found only expected public Google API/config keys.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	The HAR attributed 107 of 126 requests and 5.89 MB to non-business.google.com origins; the tracker probe found 15 third-party origins and four known tracker domains, including Google Analytics and googlesyndication. F005 medium: The initial public page has a broad analytics and third-party network footprint.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	Geolocation and notification remained in prompt state with no load-time prompt; signup hands off to Google Account authentication and the platform exposes credential/passkey capability.
be-private-and-secure `defensive-browser-policies`	issues	high	The cookie probe reported NID and three analytics cookies without Secure and with SameSite=None; the analytics cookies last 400 days. No authentication cookie lacked HttpOnly. F006 medium: Several page cookies lack defensive attributes or remain unusually long lived.
be-resilient `progressive-enhancement`	pass	high	Direct-page discoverability measured 99% raw-HTML content coverage with title, H1, and description present and no empty JS shell.
be-resilient `resilient-runtime-behaviour`	pass	high	Public content remained usable despite the signed-out account request failure; navigation, accordions, and the dedicated recovery page rendered.
be-resilient `offline-and-installable`	not-applicable	high	No manifest is linked; serviceWorker is browser-supported but this public acquisition site is not an installed application.
be-resilient `network-and-http-failure-states`	pass	high	A deliberately invalid route produced a clear 404 state with multiple relevant recovery destinations.
be-internationalised `lang-dir-and-logical-properties`	pass	high	Representative pages declare lang=en, compute LTR direction, use locale-specific /uk/ routing, and expose a language/region selector.
be-internationalised `locale-aware-data`	pass	high	The UK locale uses UK wording, local telephone presentation, and localized commercial content; no ambiguous numeric date UI was found.
be-internationalised `time-zone-correctness`	pass	high	Support hours explicitly identify BST, avoiding an unqualified local-time claim; no event scheduling/date arithmetic surface exists.
be-trustworthy `no-dark-patterns`	pass	high	The consent surface states purposes and provides explicit Reject all and Accept all controls with symmetric labels; commercial CTAs state their destination.
be-trustworthy `humane-error-handling`	pass	high	The credential handoff asks for one clearly labeled Email or phone value before progression and does not show errors before interaction.
be-trustworthy `trustworthy-input-assistance`	pass	high	The sign-in identifier field has a visible label and autocomplete=username.
be-trustworthy `safe-commercial-and-account-flows`	pass	high	Budget information is available before signup, and Start now moves to a clearly branded authentication boundary without silently creating an account.
be-sustainable `optimised-assets`	issues	high	The HAR captured 126 requests and 5.95 MB in its load window, including 2.27 MB fonts, 2.55 MB scripts, and 778 KB media. Lighthouse reported 50.7 MiB total payload, about 1.4 MiB unused JS and 193 KiB unused CSS. F004 high: The landing page ships an excessive script, font, media, and unused-code payload.
be-sustainable `no-wasteful-work`	issues	high	The HAR captured 126 requests and 5.95 MB in its load window, including 2.27 MB fonts, 2.55 MB scripts, and 778 KB media. Lighthouse reported 50.7 MiB total payload, about 1.4 MiB unused JS and 193 KiB unused CSS. F004 high: The landing page ships an excessive script, font, media, and unused-code payload.
be-sustainable `third-party-and-media-budget`	issues	high	The HAR captured 126 requests and 5.95 MB in its load window, including 2.27 MB fonts, 2.55 MB scripts, and 778 KB media. Lighthouse reported 50.7 MiB total payload, about 1.4 MiB unused JS and 193 KiB unused CSS. The HAR attributed 107 of 126 requests and 5.89 MB to non-business.google.com origins; the tracker probe found 15 third-party origins and four known tracker domains, including Google Analytics and googlesyndication. F004 high: The landing page ships an excessive script, font, media, and unused-code payload. F005 medium: The initial public page has a broad analytics and third-party network footprint.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	The audited surface is a public marketing and support site; campaign mutation is gated behind authentication and no safe agent-facing action is in scope.
be-agent-ready `on-device-inference`	not-applicable	high	The audited surface is a public marketing and support site; campaign mutation is gated behind authentication and no safe agent-facing action is in scope.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	After 20 repeated disclosure toggles, total self-size decreased by 101,846 bytes; node count changed only +2,290 (~0.2%) and no Detached constructor entered the top set.
be-memory-efficient `bounded-footprint`	issues	high	The page had 2,102 DOM elements, 82.6 MB used JS heap, and 95 loaded resources. The heap summary contained about 1.03 million nodes and 58.2 MB self-size before interaction. F014 medium: The idle marketing page has a disproportionate memory and DOM footprint.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	Neither baseline nor post-interaction heap summary exposed a growing Detached constructor; edge count decreased by 2,912 after repetition.
