What Dr Urls found on yipyip.nl
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.
- 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.
- mediumRender-blocking CSS or JavaScript
Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- lowBroken heading hierarchy
Heading hierarchy provides a semantic outline of the page content.
- lowDuplicate heading text on same page
Duplicate headings reduce the uniqueness and semantic clarity of the page structure.
- lowETag header missing on resources
Without ETags, browsers cannot efficiently validate whether cached resources have changed.
- lowImage has empty alt attribute
If a content-relevant image has an empty alt attribute, search engines cannot understand what the image depicts, and it will not appear in image search results.
- 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.
