What Dr Urls found on lagencewebnantaise.com
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.
- 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.
- 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.
- mediumNo paragraph tags in main content
Paragraph tags provide semantic structure that helps search engines understand text 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.
- lowExcessive inline CSS
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.
- lowJavaScript files are not minified
JavaScript is the most expensive resource type per byte because it must be downloaded, parsed, compiled, and executed.
- lowMeta description is too long
Truncated descriptions cut off your message to potential visitors.
- lowMissing preconnect hints for critical origins
Each new origin connection requires DNS resolution, TCP handshake, and TLS negotiation, adding 100-300ms of latency.
And 4 more. 6 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
