What Dr Urls found on tzn-digital.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.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- mediumDuplicate ID attributes found
Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.
- mediumExcessive DOM size
A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.
- mediumImage missing alt attribute
Image alt text is the primary way search engines understand image content.
- 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.
- mediumLink has empty anchor text
Anchor text is one of the strongest signals search engines use to understand the content of the linked page.
- mediumNested interactive elements detected
Nested interactive elements produce unpredictable behavior across browsers and assistive technologies.
- mediumRender-blocking CSS or JavaScript
Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.
- mediumWeb font uses font-display: block
font-display: block hides text for up to 3 seconds while the web font downloads.
- lowBelow-the-fold images not lazy loaded
Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.
- 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.
And 9 more. 7 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
