What Dr Urls found on creageneve.com

From the audit of their public home page on 22/10/2026, worst first. Each links to what it means and how it is fixed.

• medium
  Button has no accessible text

  Buttons without accessible text are announced as just 'button' by screen readers, making them impossible to identify and use for visually impaired users.

• medium
  Excessive DOM size

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

• 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
  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.

• 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.

• low
  Link is named for screen readers but has no anchor text

  Nothing is broken for users.

• low
  Missing preconnect hints for critical origins

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

• low
  Title tag is too short

  Short titles often lack the keyword richness needed to rank for target queries.
