What Dr Urls found on seriouswebdesign.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.
- highMissing landmark elements
WCAG 1.3.1 requires that page structure is programmatically determinable.
- highSlow server response time (TTFB > 3s)
Page speed is a confirmed Google ranking factor, and TTFB is the foundational component.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- highToo many HTTP requests per page
Each HTTP request incurs overhead from DNS lookup, TCP connection, TLS handshake, and server processing.
- mediumDuplicate ID attributes found
Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.
- mediumFont size too small for mobile
Small text forces mobile users to pinch-to-zoom to read content, creating a poor experience.
- mediumForm inputs missing autocomplete attribute
WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.
- 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.
- mediumMissing skip-to-content navigation link
WCAG 2.4.1 requires a way to bypass blocks repeated on every page.
- 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 CSS stylesheets
Multiple CSS files multiply HTTP requests and increase the total blocking time before the page can render.
And 13 more. 8 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
