What Dr Urls found on dasburo.nl
From the audit of their public home page on 23/10/2026, worst first. Each links to what it means and how it is fixed.
- mediumAbove-fold images not prioritized
The Largest Contentful Paint (LCP) element is often a hero image.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- mediumIcon-only button missing aria-label
Icon-only buttons are extremely common in modern UIs (hamburger menus, close buttons, search icons), but without aria-labels, they are completely opaque to screen reader users.
- mediumImages missing width and height attributes
Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.
- mediumLink has empty anchor text
Anchor text is one of the strongest signals search engines use to understand the content of the linked page.
- mediumOpen Graph og:image tag missing
Social media posts with images receive significantly more engagement than text-only posts.
- mediumRender-blocking CSS or JavaScript
Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- lowBelow-the-fold images not lazy loaded
Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.
- lowBroken heading hierarchy
Heading hierarchy provides a semantic outline of the page content.
- lowDuplicate heading text on same page
Duplicate headings reduce the uniqueness and semantic clarity of the page structure.
- lowMultiple H1 headings on page
Multiple H1 tags can dilute the topical focus of the page.
And 4 more. 6 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
