What Dr Urls found on blackdale.pl

From the audit of their public home page on 21/10/2026, 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
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Font size too small for mobile

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

• 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
  Too many external CSS stylesheets

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

• low
  CSS files are not minified

  Unminified CSS files are larger than necessary, increasing download time and delaying rendering.

• low
  Duplicate heading text on same page

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

• 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.

• low
  Excessive inline JavaScript

  Inline JavaScript cannot be cached by the browser and must be parsed and executed every time the page loads.

• 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.
