Duplicate JSON-LD Product schema

What it means

Two Product JSON-LD blocks from theme and SEO app can conflict or be ignored.

Why it happens on Shopify

SEO apps inject schema without detecting the theme output.

How to check if you have this issue

View source: count application/ld+json Product blocks.

How to fix it: precise steps

Prioritize one change at a time: adjust theme Liquid or app settings, deploy, then re-run validation (Search Console, PageSpeed, or Rich Results Test).

How to confirm it is fixed

Repeat the same checks as in the verification step after deploy. SEO effects can take days to weeks depending on crawl budget.

Impact on SEO and conversion

High-impact issues often hurt perceived performance or SEO consistency; fixes gradually improve rankings and conversion.
