What Dr Urls found on flatstudio.co
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.
- highMissing landmark elements
WCAG 1.3.1 requires that page structure is programmatically determinable.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- highVideo without captions
WCAG 1.2.2 requires captions for all prerecorded audio content in synchronized media.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- mediumDuplicate ID attributes found
Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.
- mediumExcessive third-party resource loading
Third-party resources are outside your control and often add significant payload, blocking time, and unpredictable latency.
- mediumImages missing width and height attributes
Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.
- mediumRender-blocking CSS or JavaScript
Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- mediumToo many external JavaScript files
Each external script requires a DNS lookup, TCP connection, and HTTP request.
- lowBroken heading hierarchy
Heading hierarchy provides a semantic outline of the page content.
- lowCSS files are not minified
Unminified CSS files are larger than necessary, increasing download time and delaying rendering.
