WCAG 3.2.4 — Consistent Identification

Who Is Affected

Users with cognitive disabilities, users of screen readers and other assistive technologies, users with memory impairments, and anyone who relies on predictable interface patterns to navigate websites efficiently.

What This Means

When the same functional component appears on multiple pages, it must be identified consistently. For example, if you have a "Submit" button on one form and a "Send" button on another form that performs the same function, users may not recognize they do the same thing.

This applies to buttons, links, form controls, icons, and any interactive element that serves the same purpose across different pages. The component's accessible name (what screen readers announce) and visible text should match throughout your site.

Common violations include:

• Search buttons labeled "Search" on some pages and "Find" on others
• Download links that say "PDF" sometimes and "Download PDF" other times
• Social media icons with inconsistent alt text
• Navigation elements that change labels between sections

Fix: CMS / Theme

Most consistency issues stem from template variations or different content creators using different terminology.

In Joomla:

1. Go to Extensions → Templates → Your Template
2. Review template overrides for forms, buttons, and common components
3. Standardize button text, alt text for icons, and aria-labels across all template files
4. Create a style guide document for content editors with approved labels
5. Use consistent module titles and menu item names in template positions

In WordPress:

1. Go to Appearance → Theme Editor (or use your child theme files)
2. Review template files (header.php, footer.php, sidebar.php) for repeated elements
3. Standardize button text in contact forms, search widgets, and navigation
4. Ensure social media icons have consistent alt text across all templates
5. Check that the same widgets use identical titles and labels

For both platforms:

• Create reusable components/modules for common functions like search, contact forms, and social sharing
• Document the approved terminology for each component type
• Train content editors on consistent labeling practices

Fix: Content Editor

Review your site systematically for components that serve the same function:

1. Audit similar pages — Compare contact forms, search boxes, download links, and navigation across different sections
2. Check button labels — Ensure "Submit," "Send," "Contact Us," and similar buttons use the same text for the same actions
3. Review link text — Links to the same document type (like PDFs) should have consistent formatting ("Download PDF: Title" vs "PDF: Title")
4. Standardize icons — Social media, print, email, and other functional icons need identical alt text across all pages
5. Verify form labels — Required field indicators, error messages, and help text should be worded identically

Quick consistency check:

• Search your site for all instances of key functions (contact, search, download)
• Note variations in wording, capitalization, or punctuation
• Update the inconsistent ones to match your chosen standard
