Duplicate ID attributes found: what it is, why it matters, and how to fix it

Multiple elements on this page share the same ID attribute. IDs must be unique within an HTML document. Duplicate IDs break ARIA relationships and fragment link targets.

Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element. Screen readers rely on ID-based relationships to provide context, so duplicate IDs make accessibility features unreliable. JavaScript targeting elements by ID also produces unpredictable results.

Ensure every ID attribute is unique within the page. Audit dynamically generated content (loops, components) that may produce duplicate IDs. Use unique prefixes or suffixes for generated IDs.

This is a medium-severity issue: individually modest, but it compounds — dozens of medium issues across hundreds of pages add up to a real quality deficit in how search engines assess the site. It belongs to the accessibility family of checks.
