What Dr Urls found on zentense.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
  Links implemented with JavaScript only

  While Google can execute JavaScript, it does not always follow JavaScript-based navigation.

• medium
  Above-fold images not prioritized

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

• 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
  Nested interactive elements detected

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

• medium
  Open Graph og:image tag missing

  Social media posts with images receive significantly more engagement than text-only posts.

• 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
  Below-the-fold images not lazy loaded

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

• low
  Broken heading hierarchy

  Heading hierarchy provides a semantic outline of the page content.

• low
  H1 heading is too long

  A concise H1 provides a clear, focused signal about the page's primary topic.

• 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
  Missing preconnect hints for critical origins

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