Single semantic H1 on PDP

What is being checked

Checks whether the PDP contains exactly one semantic <h1> element that represents the primary product title.

Why it matters

Without a single semantic product title, machines cannot reliably identify the product and agents may misinterpret the page context, reducing comparability and retrieval accuracy.

Failure signals

• Multiple <h1> elements are present on the page
• No <h1> element exists on the PDP
• The <h1> contains marketing copy instead of the product name
• The product name is rendered using a non-heading element

How to verify

1. Inspect the DOM structure of the PDP and count the number of <h1> elements.
2. Verify that exactly one <h1> is present and that it contains the product name.

Recommended fix

Ensure that the primary product title is rendered as a single semantic <h1> element and that no additional <h1> elements are used on the PDP.
