What Dr Urls found on dribba.com

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.

• 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
  Horizontal scrolling likely on mobile

  Horizontal scrolling is a top mobile usability failure that Google actively penalizes in mobile search rankings.

• high
  Missing landmark elements

  WCAG 1.3.1 requires that page structure is programmatically determinable.

• medium
  Excessive DOM size

  A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.

• medium
  Font size too small for mobile

  Small text forces mobile users to pinch-to-zoom to read content, creating a poor experience.

• medium
  Form inputs missing associated labels

  Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.

• medium
  Nested interactive elements detected

  Nested interactive elements produce unpredictable behavior across browsers and assistive technologies.

• 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.

• low
  Duplicate heading text on same page

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

• low
  Excessive inline CSS

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

• low
  Image 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.

• 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.
