Product structured data tells search engines and shopping agents what a page is selling, at what price, and whether it is available.
Most Shopify themes generate some product markup. Its quality varies widely, and incomplete markup is frequently ignored entirely rather than partially honoured.

Example
The failures that matter
Markup that contradicts the page. A schema price differing from the rendered price is a violation and can cost rich results across the site. This happens constantly on stores where markup and display are generated separately. Stale availability.InStock on a sold-out product misleads shopping surfaces and agents, and erodes feed trust.
Missing offers. Product without a valid offer is not eligible for product rich results.
Duplicate markup. A theme and an app both emitting Product schema produces conflicting blocks on one page. Check the rendered source, not the template.
Variant confusion. Marking up one variant’s price on a page presenting several. See product variant markup.
Review markup without visible reviews. A violation, and one that attracts manual action.
