What Dr Urls found on studiobig.co.uk

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
  Structured data has validation errors

  Invalid structured data is completely ignored by search engines — it provides no benefit and the page will not be eligible for rich results.

• 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
  Duplicate ID attributes found

  Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.

• medium
  Empty heading tag found

  Empty headings waste an opportunity to provide keyword signals and structural context.

• medium
  Image file too large (>500 KB)

  Images typically account for 50-75% of a page's total weight.

• 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
  Link has empty anchor text

  Anchor text is one of the strongest signals search engines use to understand the content of the linked page.

• 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
  Thin content (too few words)

  Google's Helpful Content system explicitly targets thin, low-value pages.

• medium
  Too many external CSS stylesheets

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

• medium
  Too many external JavaScript files

  Each external script requires a DNS lookup, TCP connection, and HTTP request.
