What Dr Urls found on fidesio.com
From the audit of their public home page on 28/10/2026, worst first. Each links to what it means and how it is fixed.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- mediumCanonical URL is relative instead of absolute
Relative canonical URLs can be misresolved by search engines in certain edge cases, especially when pages are accessed through proxies, CDNs, or alternative domains.
- mediumDuplicate ID attributes found
Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.
- 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.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- lowApple touch icon missing
The apple-touch-icon provides a branded icon when users bookmark your site on iOS devices.
- lowBroken heading hierarchy
Heading hierarchy provides a semantic outline of the page content.
- lowExcessive inline CSS
Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.
- lowH1 heading is too long
A concise H1 provides a clear, focused signal about the page's primary topic.
- lowImages missing responsive srcset
Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
- lowImages not using modern format
WebP images are 25-35% smaller than equivalent JPEG images, and AVIF offers even greater savings.
- lowLink is named for screen readers but has no anchor text
Nothing is broken for users.
And 9 more. 8 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
