How to fix missing h1 on WooCommerce

Steps for WooCommerce

1. For product pages: WordPress Admin → Products → open the product → the 'Product name' field at the top is output as the H1 by most WooCommerce themes (via the woocommerce_template_single_title hook). Ensure the product name is filled in.
2. For shop/category pages: WordPress Admin → Products → Categories → edit the category → the 'Name' field becomes the H1.
3. For standard pages/posts: WordPress Admin → Pages (or Posts) → open the page → in the Gutenberg editor, the first block should be a 'Heading' block set to H1, OR the page title field at the very top (above the editor) renders as H1.
4. If the theme does not output an H1, open your child theme's single-product.php or archive-product.php and add: <h1 class="product_title"><?php the_title(); ?></h1>.
5. Use the free 'Rank Math' or 'Yoast SEO' plugin — both include on-page analysis that flags missing H1s per page/product.
6. Verify with View Page Source and search for '<h1>'.

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.
