What Dr Urls found on elephant-technologies.fr
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.
- highSlow server response time (TTFB > 3s)
Page speed is a confirmed Google ranking factor, and TTFB is the foundational component.
- 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.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- 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.
- mediumMissing canonical tag
Canonical tags are the strongest signal you can send to search engines about which URL should be indexed when multiple URLs serve similar content.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- lowCSS files are not minified
Unminified CSS files are larger than necessary, increasing download time and delaying rendering.
- lowImages missing responsive srcset
Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
- lowLink is named for screen readers but has no anchor text
Nothing is broken for users.
- lowMissing preconnect hints for critical origins
Each new origin connection requires DNS resolution, TCP handshake, and TLS negotiation, adding 100-300ms of latency.
- lowOpen Graph og:url tag missing
The og:url tag acts as a canonical for social shares, consolidating likes, shares, and comments to a single URL.
And 2 more. 5 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
