Layout XML, templates and CMS blocks
Check the title block in the affected layout and possible theme adjustments. The product name in the dataset alone does not guarantee a visible main heading.
The page title can come out of the layout, while an integrated CMS block again contains a main heading. For individual themes, both output locations must be considered together.
Where to check the setting in Magento
Compare the page title block of the layout with headings from CMS or page builder content. For product pages, you control the active theme and overriding templates. An optically hidden title can still be present in the HTML as H1.
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 Magento
Check the product page, category and CMS landing page separately for their complete outline. A fixed heading level of a block does not automatically fit into all three contexts.
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.
Reference: Magento Open Source or Adobe Commerce with classic storefront. Consider store views and extensions; other storefront architectures have their own configurations.
