Website Check

Check your website in a real browser, just as a visitor sees it. You learn how fast it loads, how well search engines read it, how accessible and secure it is and which trackers load before consent. You get the fixes sorted by importance.

Check websiteHow we check
  • Lab and real users. We measure speed ourselves and show the data from real visitors that Google publishes alongside it.
  • Security and privacy in the same report. The report covers everything from the certificate and the security headers to the trackers that load before cookie consent.
  • Fixes for your system. If your website runs on WordPress, Shopify or Wix, many fixes also include the steps for exactly that system.

Which website should we check?

You can enter the home page or a single subpage.

Reading the result

The overall grade is the weighted average of five areas: speed 25%, SEO, accessibility and security 20% each, privacy 15%.

  1. Very good, 90 to 100 points

    There are no important problems. With small improvements, you keep this level.

  2. Good, 75 to 89 points

    The basics are right. A few fixes make the website faster and more secure.

  3. Fair, 60 to 74 points

    The website works, but some problems affect visitors and rankings.

  4. Weak, 40 to 59 points

    There are problems with speed, security or privacy that directly affect visitors.

  5. Urgent, 0 to 39 points

    Basic functions are at risk. Fix these errors first.

  • SpeedHow quickly the page appears on a smartphone and becomes usable. The score is the Lighthouse performance score.
  • SEOWhether search engines find the page and understand it correctly: title, description, canonical, robots.txt and sitemap.
  • AccessibilityHow well people with disabilities can use the page. We measure the part that can be checked automatically.
  • SecurityHTTPS, certificate, TLS version and the security headers that protect the browser.
  • PrivacyCookies and trackers that load before cookie consent. The result is a technical observation, not a legal assessment.

Lab measurement

We open the page once from Germany and simulate a smartphone with a slow mobile connection. The result can differ by a few points from PageSpeed Insights, because location and hardware are different.

Real user data

Google publishes the values of real Chrome visitors from the last 28 days. For websites with few visitors, this data does not exist; then you see only the lab measurement.

How we check your website

We open your website the way a visitor sees it for the first time: we do not click anything and do not give cookie consent. The check runs in six steps.

  1. Opening the page

    We open your address, follow every redirect and check whether http redirects to https.

    Checked

    • HTTP
    • HTTPS

  2. Testing the connection

    We read the certificate's validity, lifetime and chain, the TLS version and the security headers.

    Checked

    • TLS
    • HSTS
    • CSP

  3. The search engine's view

    We read robots.txt and sitemap and check whether the page can be added to the search index.

    Files

    • robots.txt
    • sitemap.xml

  4. Visit without consent

    We open the page in a real browser and record which cookies are set without consent and which services receive requests.

    Checked

    • Chromium
    • Set-Cookie

  5. Speed and accessibility

    Lighthouse measures in a fresh browser with a simulated smartphone and a slow connection. axe-core checks accessibility.

    Tools

    • Lighthouse
    • axe-core

  6. Real users

    We add the values of the last 28 days from Google's Chrome UX Report. For this, Google learns only the website's address.

    Source

    • CrUX

What we do not check

  • Only the page you enter is measured; the rest of the website is not crawled.
  • Nothing is clicked on the page, so areas behind a login stay invisible.
  • Only the automatically measurable part of accessibility is checked. This is not an assessment under the BFSG (German Accessibility Strengthening Act).
  • The privacy results are technical observations, not a legal assessment.
  • We measure from Germany; visitors from other countries may experience different load times.
