Express website audit

Analyse a public page in seconds: availability, server performance, on-page SEO, accessibility, responsive signals, UX, tracking, and key security headers. The result provides module scores and a prioritised action plan.

What the tool checks

A first review across 7 areas

The audit combines technical and editorial signals that can be detected directly in the HTTP response and HTML.

SEO

Title, meta description, H1/H2, canonical, hreflang, structured data, Open Graph, and image alt attributes.

Performance

TTFB, total time, HTML weight, redirects, and PageSpeed metrics when configured.

Accessibility

Document language, alternative text, form labels, and accessible names for buttons and links.

Security

HTTPS, HSTS, CSP, nosniff, Referrer-Policy, Permissions-Policy, and frame protection.

Mobile

Viewport, width=device-width, and responsive hints detectable in the document.

UX

Structure, calls to action, contact paths, forms, and trust signals.

Tracking

Indicative detection of GA4, GTM, Matomo, Plausible, and major marketing pixels.

Run an audit

Use a public URL accessible over http or https.

Interpret and continue the audit

Audit Express Web is designed as a fast diagnosis: it identifies visible fundamentals and helps decide what to verify first. A good score alone does not guarantee rankings or conversions, but it quickly highlights frequent omissions.

Intentional limitation: the tool does not run a full browser. Real rendering metrics (LCP, CLS, TBT) are only displayed when PageSpeed is configured on the server.

SEO

Go deeper on on-page SEO

Title, meta description, headings, and content must be interpreted in the context of the page.

Performance

Reduce loading time

HTML weight and TTFB provide a first indication before a complete browser audit.

Responsive

Check mobile-first basics

The viewport is essential, but testing on real screen sizes remains necessary.

Security

Strengthen protection

HTTP headers improve browser-side protection but must be adapted to the site.
