Speed
Render-blocking requests
550 ms2 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.
2 third-party services on the page
2 third-party services load with your homepage (cyberjack.nl and Google Fonts), adding 67 KiB and 2 ms of main-thread time.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Core Web Vitals
Not enough real-visitor data yet
Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Accessibility
16 text elements with low contrast
16 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Links look like plain text
1 link inside paragraphs relies on colour alone to stand out.
All page content should be contained by landmarks (13 elements)
All page content should be contained by landmarks: 13 elements on the page fail this check, rated moderate by axe-core.
No main landmark
The page has no <main> landmark, so screen-reader users cannot jump straight to the content.
1 form field without a label
1 form field has no label, so screen readers announce an empty box and autofill guesses.

36 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 40 WCAG 2.2 A/AA and best-practice rules on the phone render: 36 passed and 4 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
