What Dr Urls found on marsmedia.nl
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.
- highLinks implemented with JavaScript only
While Google can execute JavaScript, it does not always follow JavaScript-based navigation.
- mediumDuplicate ID attributes found
Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.
- lowExcessive inline CSS
Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.
- lowExcessive inline JavaScript
Inline JavaScript cannot be cached by the browser and must be parsed and executed every time the page loads.
- lowImages missing responsive srcset
Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
- lowMultiple H1 headings on page
Multiple H1 tags can dilute the topical focus of the page.
