What Dr Urls found on firststars.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.
- highLinks implemented with JavaScript only
While Google can execute JavaScript, it does not always follow JavaScript-based navigation.
- highMissing landmark elements
WCAG 1.3.1 requires that page structure is programmatically determinable.
- 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.
- mediumForm inputs missing associated labels
Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.
- 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.
- mediumNo paragraph tags in main content
Paragraph tags provide semantic structure that helps search engines understand text content.
- mediumOpen Graph og:image tag missing
Social media posts with images receive significantly more engagement than text-only posts.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- lowExcessive inline JavaScript
Inline JavaScript cannot be cached by the browser and must be parsed and executed every time the page loads.
