Onion Studio - Branding & Web Agency

What Dr Urls found on onionstudio.be

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.

• medium
  Above-fold images not prioritized

  The Largest Contentful Paint (LCP) element is often a hero image.

• medium
  Cache-Control header missing

  Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.

• medium
  Images missing width and height attributes

  Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.

• medium
  Link has empty anchor text

  Anchor text is one of the strongest signals search engines use to understand the content of the linked page.

• medium
  Render-blocking CSS or JavaScript

  Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.

• medium
  Scripts without async or defer

  Synchronous scripts halt HTML parsing while the browser downloads and executes them.

• medium
  Thin content (too few words)

  Google's Helpful Content system explicitly targets thin, low-value pages.

• low
  Duplicate heading text on same page

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

• low
  Images missing responsive srcset

  Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.

• low
  Images not using modern format

  WebP images are 25-35% smaller than equivalent JPEG images, and AVIF offers even greater savings.

• low
  Link uses generic anchor text

  Descriptive anchor text helps search engines understand the topic of the linked page.

• low
  Missing preconnect hints for critical origins

  Each new origin connection requires DNS resolution, TCP handshake, and TLS negotiation, adding 100-300ms of latency.
