What Dr Urls found on herold.at
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.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- mediumAbove-fold images not prioritized
The Largest Contentful Paint (LCP) element is often a hero image.

- lowCSS files are not minified

Duplicate headings reduce the uniqueness and semantic clarity of the page structure.

Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.
- lowImages missing responsive srcset
Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
And 4 more. 7 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
