What Dr Urls found on devsource.fr
From the audit of their public home page on 21/10/2026, 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.
- mediumExcessive DOM size
A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.
- lowApple touch icon missing
The apple-touch-icon provides a branded icon when users bookmark your site on iOS devices.
- 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.
- 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.
- lowToo many on-page links
PageRank is divided among all links on a page, so more links means less equity passed to each destination.
