What Dr Urls found on wienit.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.
- highCacheable response sets a cookie, so no CDN will cache it
The two headers contradict each other, and the contradiction is silent: the page looks cached, the CDN is configured, and every request still pays full origin latency.
- 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.
- 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.
- mediumOpen Graph og:image tag missing
Social media posts with images receive significantly more engagement than text-only posts.
- mediumStylesheets loaded in body
Stylesheets in the body block rendering of subsequent content and can cause visible layout shifts as styles are applied incrementally.
- lowBelow-the-fold images not lazy loaded
Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.
- lowETag header missing on resources
Without ETags, browsers cannot efficiently validate whether cached resources have changed.
- lowExcessive inline JavaScript
Inline JavaScript cannot be cached by the browser and must be parsed and executed every time the page loads.
- lowImages missing responsive srcset
Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
- lowSocial media preview is incomplete
Incomplete social previews reduce the visual appeal and click-through rate of shared links.
- lowTitle tag is too short
Short titles often lack the keyword richness needed to rank for target queries.
