Single-product template and shop blocks
Check if an individually built product layout has removed the product title. The visible product name should continue to be issued as a suitable main heading.
Check the product name in the single product template, as well as headings of description, related products, and upsells. A product block taken from a detailed template can create an inappropriate main heading in lists.
Where to check the setting in WooCommerce
Depending on the theme, check the single product template or product title block in the website editor. A product description formatted manually as H1 can collide with the automatically output product name. Compare a simple and a variable product.
Example of this specific finding
Illustrative control case: An article shows its title only as a styled div; the first semantic heading is an H2 for a subsection.
<h1>So warten Sie Ihre Fahrradbremsen</h1>
<h2>Benötigtes Werkzeug</h2>follow-up audit in WooCommerce
Compare a product detail page and product listing with the same articles. The hierarchy must fit to the side, not just to the individual block.
The central article title is issued as a suitable main heading. After that, control the entire structure and not just the optical size.
Derogations and scope
A missing H1 element alone does not prove a ranking loss. The correction is intended to make the main topic structurally understandable.
Regarding: WooCommerce on WordPress. Block and classic product templates as well as SEO extensions can have different output locations.
