How to Fix Malformed JSON-LD Schema Markup

errorThe Problem

Your page has JSON-LD schema markup, but it contains syntax errors — missing commas, unescaped quotes, unclosed brackets, or invalid data types. Malformed JSON-LD is completely ignored by Google.

trending_upWhy It Matters for SEO

Schema markup with syntax errors is worse than no schema at all — because you think you have it while Google sees nothing. This means no rich results, no star ratings, and no price display in search listings, despite having the code on your page.

Use the json filter in Liquid to properly escape values: {{ product.description | json }}
5
Re-test after fixing.
