How to fix heading order on Wix

Steps for Wix

1. Open the Wix Editor for your site.
2. Click any Text element that is used as a heading. In the text toolbar that appears, open the 'Paragraph Styles' dropdown (it may show 'Heading 1', 'Heading 2', etc.) and select the correct heading level to match the sequential order on the page.
3. Note: Wix maps its 'Heading 1–6' paragraph styles to <h1>–<h6> HTML tags. Choose the style that corresponds to the correct structural level, not the visual size you prefer.
4. If you need a different visual size without changing the structural heading level, use the font-size control within the same heading style rather than switching to a different heading level.
5. Publish the site, then run WAVE or axe DevTools on the live URL to verify the heading outline is sequential.

<!-- INCORRECT: skips from H1 directly to H3 -->
<h1>Product Name</h1>
<h3>Key Features</h3>   <!-- ❌ skips H2 -->
  <h4>Detail One</h4>

<!-- CORRECT: sequential, no levels skipped going downward -->
<h1>Product Name</h1>
<h2>Key Features</h2>   <!-- ✅ follows H1 -->
  <h3>Detail One</h3>   <!-- ✅ follows H2 -->

What is heading order?

Every webpage uses heading tags — H1, H2, H3, H4, H5, and H6 — to organize content into a hierarchy, like chapters and sub-chapters in a book. "Heading order invalid" means that hierarchy has a gap or jump: for example, jumping straight from an H1 to an H3, or using an H4 immediately after an H2. Screen readers and assistive technologies rely on this outline to help users navigate a page quickly. Headings should always nest in order — you can go up levels freely, but you should never skip a level going down.

For the roughly 1-in-4 shoppers who use assistive technology, broken heading order makes it very hard to navigate your pages — they may completely miss product sections, key offers, or checkout steps. This is a WCAG 2.1 Level AA requirement (Success Criterion 1.3.1 and 2.4.6), so non-compliance creates real legal risk under laws like the ADA (USA), the European Accessibility Act, and the UK Equality Act. Beyond accessibility, heading structure is one of the signals Google uses to understand your page's content hierarchy; a clean, logical outline helps search engines index and rank your pages more accurately. Fixing heading order is typically a quick win with immediate benefits for both users and SEO.
