How good is your website, really?
A free check for load time, accessibility, SEO and security.
About the check
- Performance
- How fast the page loads and how quickly it becomes usable. Measured are LCP and CLS, two of Google's three Core Web Vitals, plus Total Blocking Time. That last one is not a Core Web Vital itself but the lab value that estimates responsiveness: the third metric (INP) can only be measured on real visitors. Plus the most common brakes: oversized images, blocking scripts, missing compression, unused CSS and JavaScript.
- Accessibility
- Contrast, alternative text, form labels, heading structure, correct ARIA markup and the size of tap targets. Checked with Lighthouse and axe-core against WCAG 2.2 Level AA. The legal requirement today is 2.1 AA; 2.2 is where the next edition of the European standard is heading.
- Best practices
- HTTPS, console errors and deprecated APIs.
- SEO
- Title, meta description, indexability, robots.txt and canonical. Whether Google can read your site cleanly at all.
- Security and technology
- Certificate, HTTPS redirect, TLS version, security headers, cookie flags and disclosed server versions.
- DNS and email
- SPF, DMARC, CAA and DKIM. These records help decide whether your email arrives or lands in spam.
The four scored areas run from 0 to 100, on the same thresholds as Google Lighthouse:
- 90–100 good
- 50–89 needs work
- 0–49 critical
For context: sites built on page builders and bought themes often land in the red for mobile performance, because every visit loads the whole package rather than the part the page needs. A low score is not unusual, but it is a disadvantage against everyone doing it better.
It is automated, and that has limits.
- Automated testing
- Automated tests find roughly 30 to 40 percent of accessibility requirements. Whether an alternative text describes the image usefully or just contains some word is not something a machine can judge. Whether the page can actually be operated with a keyboard only shows when someone does it.
- Lab conditions
- The measurement is also a lab situation: one page, one device, one network. What your actual visitors experience may differ.
- What a clean result does not mean
- So the check shows you where something is wrong. It does not tell you that everything is fine.
And then?
You get the results immediately, with the individual findings in detail.
If you then want to know what is worth doing and in what order: the analysis from €490 goes through the site by hand as well, including keyboard and screen reader testing.
