How to fix missing h1 on Adobe Commerce (Magento)

Steps for Adobe Commerce (Magento)

1. For product pages: Catalog → Products → open the product → the 'Product Name' field is used as the H1 by default via the page_title block in the product view layout.
2. For category pages: Catalog → Categories → open the category → the 'Name' field renders as the H1.
3. To override the H1 independently of the product name, go to the product edit page → Search Engine Optimization tab → fill in the 'Meta Title' field; some themes use this as the visible H1 — check your theme's catalog/product/view/title.phtml.
4. To modify at the template level: in your custom theme, edit app/design/frontend/<Vendor>/<theme>/Magento_Catalog/templates/product/view/title.phtml and ensure the title output is wrapped in <h1 ...>.
5. For CMS pages (Home, About, etc.): Content → Pages → open the page → in the Page Information tab, fill in the 'Content Heading' field — this renders as the H1 above the content block.
6. Flush cache under System → Cache Management after saving, then verify with View Page Source.

What is missing h1?

An H1 is the main heading on a webpage — think of it as the title printed at the top of a magazine article. It tells both visitors and search engines what the page is about in one clear phrase. Every page should have exactly one H1 tag (not zero, not three), and it should describe the page's primary topic using words your customers actually search for. On a product page that might be the product name; on a category page it might be the category name; on your homepage it might be your brand's core value proposition.

Search engines use the H1 as one of the strongest on-page signals to understand what a page covers and how it should rank. A missing H1 means Google has to guess the page topic from other less-reliable signals, which can lower your rankings for the exact keywords you care most about. For shoppers, a page without a visible heading looks unfinished and untrustworthy, hurting conversion rates. Accessibility tools and screen readers also rely on the H1 to help visually impaired users navigate your page — missing it creates a legal accessibility risk in many jurisdictions.
