Arco Website Design and Development

What Dr Urls found on arcowebdesign.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.

• high
  Slow server response time (TTFB > 3s)

  Page speed is a confirmed Google ranking factor, and TTFB is the foundational component.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Cache-Control header missing

  Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.

• 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.

• medium
  Too many external CSS stylesheets

  Multiple CSS files multiply HTTP requests and increase the total blocking time before the page can render.

• low
  Apple touch icon missing

  The apple-touch-icon provides a branded icon when users bookmark your site on iOS devices.

• 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
  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.

And 4 more. 8 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
