Favicon & Branding

No print-specific styles detected

When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

Mobile-Readable Font Sizes

92% of visible text renders at >= 12 CSS px (33 below threshold)

REVIEW

92% of visible text renders at >= 12 CSS px (33 below threshold)

33 text node(s) render below 12 CSS pixels on mobile

Mobile browsers default the root font-size to 16 px; text below ~ 12 px (75% of root) is hard to read without zooming. WCAG 1.4.4 (Resize Text) requires the page to support 200% zoom without loss of functionality -- which most layouts handle, but small base text still costs readability and conversion. Audit which selectors set sizes below 12 px (often footers, fine print, table cells) and bump them to 14-16 px or use rem units that scale with user preferences. Examples: <tspan> 11.0px ("OpenAI"); <text> 11.0px ("GPTBot"); <tspan> 11.0px ("Anthropic"); <text> 11.0px ("ClaudeBot"); <text> 11.0px ("Google-Extended").

Page Structure — as a screen reader sees it

Heading Hierarchy

18 headings, 1 skip(s)

PASS

18 headings, 1 skip(s)

Single H1 present

Heading level skipped: H2 → H4 (missing H3)

Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

H1 Which websites block AI?
H2 Who blocks AI training, by type of site
H2 The wall, month by month
H2 How we check
H3 Websites post rules for bots
H3 We read those rules every day
H3 Then we knock on the front door
H2 Three kinds of AI bots
H3 AI training
H3 AI search

Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

Why this matters

Skipping heading levels breaks the document outline — screen-reader users lose track of section nesting.

Learn more ▾

Screen reader users navigate by jumping between headings (H1 → H2 → H3). Skipping (H1 → H3) breaks the sense of hierarchy. Use sequential levels even if you don't like the default styling — restyle with CSS instead. WCAG 1.3.1 (Info and Relationships) treats this as an A failure.

Form Input Types

1 input(s) using type=text where a specific type would help

PASS

1 input(s) using type=text where a specific type would help

Input "domain" should use type="url" (currently type="text")

Field name "domain" suggests type="url". Wrong type loses mobile keyboard hints, browser autofill, and free format validation. Change to <input type="url">.

No `<meta name="theme-color">` -- browser chrome falls back to default

Without `theme-color`, Android Chrome's status bar and iOS Safari's toolbar fall back to a generic gray. Adding a single hex color in `<meta name="theme-color" content="#0066cc">` tints them to your brand color across all mobile browsers.

Lighthouse Accessibility Audits

Score 99/100 — 1 failing, 28 passed

PASS

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

Navigation

Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies. Learn more about heading order.

Why this matters

Performance issues directly impact user engagement and conversion rates.
