What Dr Urls found on omh.net

From the audit of their public home page on 25/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Cacheable response sets a cookie, so no CDN will cache it

  The two headers contradict each other, and the contradiction is silent: the page looks cached, the CDN is configured, and every request still pays full origin latency.

• high
  Content wider than viewport on mobile

  Horizontal scrolling on mobile is one of the most common mobile usability failures flagged by Google's Mobile-Friendly Test and Google Search Console.

• high
  Video without captions

  WCAG 1.2.2 requires captions for all prerecorded audio content in synchronized media.

• 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
  Media element autoplays with sound

  Autoplaying audio interferes with screen reader output, making the page essentially unusable for visually impaired users.

• medium
  No structured data (schema.org) found

  Structured data enables rich results (star ratings, FAQ dropdowns, recipe cards, product prices, breadcrumbs, etc.) that dramatically increase click-through rates — some rich resu…

  Render-blocking CSS or JavaScript

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

• low
  Below-the-fold images not lazy loaded

  Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.

• low
  ETag header missing on resources

  Without ETags, browsers cannot efficiently validate whether cached resources have changed.

• low
  Excessive inline CSS

  Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.

• 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.

And 2 more. 3 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
