How to fix multiple h1 on Adobe Commerce (Magento)

Steps for Adobe Commerce (Magento)

1. Locate the relevant template file via the Admin or directly in the file system: for product pages it is app/design/frontend/<Vendor>/<theme>/Magento_Catalog/templates/product/view/type/ or the base catalog/product/view.phtml.
2. Open the template and search for '<h1' — the product name wrapper (typically <span class="base" itemprop="name">) inside an H1 is correct. Remove or downgrade any additional H1 tags to H2.
3. Check category page templates in Magento_Catalog/templates/category/view.phtml — the category name H1 should be the only H1.
4. Check layout XML files (e.g. catalog_product_view.xml) for any blocks that inject an H1 via widget or CMS block.
5. Clear the Magento cache (System → Cache Management → Flush Magento Cache) after changes.
6. Preview pages and confirm with DevTools.

What is multiple h1?

An H1 is the main heading on a webpage — think of it as the title of a book chapter. It tells both visitors and search engines what the page is fundamentally about. HTML allows you to put as many H1 tags on a page as you like, but best practice — and Google's own guidance — is to use exactly one H1 per page. When a page has dozens or even hundreds of H1 tags (which can happen when a theme or plugin wraps every product card, section, or widget in an H1), the heading structure breaks down entirely. Everything below the H1 should be organized with H2, H3, and so on — like chapters and subheadings in a document.

Google uses heading structure — especially the H1 — as a strong signal for understanding what a page is about and for generating the blue title link shown in search results. A page with 95 H1 tags sends contradictory signals: Google cannot determine which heading represents the page's true topic, which can dilute your keyword relevance and hurt rankings. Beyond SEO, screen readers used by visually impaired shoppers rely on a single H1 to orient users when they land on a page — multiple H1s create a confusing and legally risky accessibility experience (WCAG 2.x guidelines and laws like the ADA reference proper heading structure). Fixing this is typically a quick template or theme change, yet it can meaningfully improve both your organic search visibility and the accessibility of your store.
