Free Website Test

Last updated April 2026

A free website test checks your site for problems you might not know about. Performance issues that drive visitors away, accessibility violations that exclude users and risk fines, missing security headers, GDPR consent failures, SEO gaps that keep you out of search results, and AI readiness gaps that leave you invisible to AI-powered search. Our scan covers all of these in about 20 seconds and returns a detailed report with specific findings and plain-language explanations of how to fix them.

What gets tested

The scan analyzes your website across six categories. Each one covers a different dimension of website quality, from how fast your pages load to whether your cookie consent implementation meets EU requirements.

Performance. How fast your site loads and how responsive it feels. This includes Core Web Vitals (the metrics Google uses as a search ranking signal), loading times, and resource efficiency. Only 48% of mobile websites currently pass Google's Core Web Vitals thresholds.

SEO. Whether search engines can find, understand, and rank your content. The scan checks meta tags, structured data, robots.txt, XML sitemaps, Open Graph tags, and mobile configuration.

Accessibility. Whether your site works for people with visual, motor, cognitive, or auditory impairments. The scan runs axe-core, an industry-standard testing engine, against WCAG 2.1 A and AA rules in both desktop and mobile viewports. 94.8% of the top million websites have at least one detectable accessibility failure.

Trust and security. Whether your site meets GDPR and ePrivacy requirements and is configured to protect visitors. The scan detects your cookie consent platform, checks for a visible reject option, monitors pre-consent tracking, looks for privacy policy links and business identification, inspects your TLS certificate and security headers (CSP, HSTS, X-Content-Type-Options, Referrer-Policy, X-Frame-Options, Permissions-Policy), checks for exposed server versions, and cross-references your URL against Google Web Risk for malware or phishing flags.

Website quality. Whether your site is built and maintained properly, including broken links, HTML validation, heading structure, responsive design, and third-party script load.

AI readiness. Whether your site is prepared for AI-powered search engines like ChatGPT, Perplexity, and Google AI Overviews. The scan checks which AI crawlers can access your content via robots.txt, whether you have an llms.txt file, whether your structured data is complete enough for AI to identify your business, whether your content is visible without JavaScript (most AI crawlers do not execute JS), and whether your page uses semantic HTML and content patterns that AI systems are more likely to cite.

How scoring works

Each category receives a score from 0 to 100:

  • 90 to 100 (green): Meets or exceeds current standards
  • 50 to 89 (orange): Issues that should be addressed
  • 0 to 49 (red): Significant problems requiring immediate attention

The overall score is a weighted average across all six categories, with performance, SEO, accessibility, and trust and security each weighted at 20%, and website quality and AI readiness at 10% each.

Accessibility uses a deduction model: the score starts at 100 and points are subtracted for each violation based on severity. All other categories use a weighted average of individual checks, where each check contributes based on its importance.

What to expect in your results

The report shows your overall score and a breakdown by category. For each category, you see every individual check with its status (pass, warning, or fail) and a plain-language explanation of what it means.

Failing checks include:

  • What the issue is in clear, non-technical language
  • Why it matters for your business or your visitors
  • Which specific elements on your page are affected

The results are designed to be actionable whether you fix issues yourself or hand the report to a developer. Each finding links to the specific standard or regulation it relates to.

What most free tools miss

Most free website testing tools check one or two dimensions. Google's PageSpeed Insights measures performance. WAVE checks accessibility. SSL Labs checks your certificate. None of them check whether your cookie banner actually blocks tracking before consent, whether your site exposes its server version, or whether you meet the requirements of the EU Accessibility Act.

This scan covers all six dimensions in a single test. It is particularly relevant for businesses operating in the EU, where GDPR consent violations, accessibility non-compliance, and missing security measures carry real financial risk. It also checks whether your site is visible to AI-powered search engines, which is becoming a competitive factor as traditional search volume declines.
