Why Use Our Tool
Every test uses real cURL requests, live HTTP header inspection, and DOM parsing — zero simulation.
Live checks for meta titles (length), descriptions, canonical URLs, H1 usage, heading hierarchy, robots directives, sitemap existence, keyword alignment, and alt-text keyword stuffing.
Measures real TTFB, checks GZIP/Brotli compression, CDN detection, HTTP/2, Cache-Control headers, render-blocking scripts, lazy loading, and HTML document size.
Validates lang attribute, alt text, form labels, skip links, ARIA landmark roles, empty buttons, new-tab warnings, iframe titles, and tabindex anti-patterns.
Real HTTP header inspection for CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, mixed content, eval() usage, and exposed server versions.
Checks viewport meta tag, user-scalable restrictions (WCAG violation), fixed-pixel overflow, Apple touch icons, Web App Manifest, and theme-color meta.
Fetches up to 30 links via cURL, detects 404/410 errors, redirect chains (multiple hops), slow-responding links, and missing rel="noopener" on external links.
Inspects Set-Cookie response headers for Secure, HttpOnly, SameSite attributes, and excessive expiry durations — real server response analysis.
Checks HTTP→HTTPS redirect consistency, www/non-www canonicalisation, CDN presence, server version exposure, and response time benchmarking.
Detects missing DOCTYPE, missing charset, deprecated tags (<font>, <center>, <marquee>), duplicate IDs, <style> in body, and counts DOMDocument parse errors.
Detects Google Fonts without preconnect hints, missing display=swap parameter, @font-face without font-display, and problematic line-height values.
Checks for JSON-LD presence, validates @context and @type properties, detects missing BreadcrumbList, and reports JSON syntax errors.
One-click download of a fully branded PDF with score ring, category bars, full issue list with severity badges, and step-by-step fix recommendations for every finding.

An AI website tester is a next-generation web auditing tool that applies server-side intelligence to systematically evaluate every technical, structural, and content dimension of a webpage in real time. Unlike static checkers, our tool performs live HTTP requests via PHP cURL — reading actual response headers, parsing the real DOM, and running over 50 checks against your live server. To use this free online website testing tool, simply enter a URL, choose your test categories, and click Analyze. Within seconds you'll receive a comprehensive audit covering SEO (meta tags, canonicals, sitemaps), Core Web Vitals (TTFB, GZIP, caching), WCAG 2.1 accessibility (alt text, labels, ARIA roles), security (CSP, HSTS, XSS vectors), mobile usability (viewport, touch targets), live broken link detection, cookie security attributes, DNS configuration, HTML quality validation, and typography best practices. The best practice for using an AI website audit tool is to run it after every significant update, before major launches, and on a regular monthly schedule to catch regressions early. Developers, SEO professionals, and digital marketers rely on these insights to maintain competitive search rankings, protect users, and deliver fast, inclusive web experiences across all devices.
