Broken structured data doesn't just fail to help. It actively confuses assistants and costs you trust. These six mistakes show up on most Shopify audits.
Each one is a reason an assistant doubts your facts. Each one is fixable today.
What structured data mistakes confuse AI on Shopify?
1. Empty schema skeletons
Themes ship Product schema with no values inside. Valid structure, zero information.
Fill every field with real data.
2. Schema that contradicts the page
A schema price or availability that disagrees with the visible page makes the assistant trust neither.
Match schema to the page, always.
3. Fake or borrowed review markup
Marking up ratings you don't have is a trust risk and can get you ignored or penalized.
Only mark up real reviews.
4. Wrong schema type
Tagging a product as an Article, or a collection as a Product, sends the wrong signal about what the page is.
Use the correct type for each page.
5. Unvalidated markup
Schema with errors and warnings may be partly ignored. You won't know unless you check.
Run every template through the Schema.org validator.
6. Missing key fields
Product schema without price, availability, or brand gives an assistant too little to act on.
Complete the core fields on every product.

Frequently Asked Questions
Can bad structured data hurt more than no structured data?
Yes. Contradictory or invalid schema actively confuses assistants and undercuts your other facts, while fake review markup can get you ignored. Wrong schema is worse than a clean gap.
How do I find schema mistakes on my store?
Run each product template through a schema validator and read the output for empty fields, errors, and mismatches with the visible page. Fix the warnings and re-validate.
Do I need review schema?
Only where you have real reviews. Never mark up ratings you don't have. Genuine review data gives assistants a trust signal, but fabricated markup is a liability.
How often should I check my schema?
Any time you change product data or your theme. Schema drifts out of sync with edits, so treat a mismatch between schema and page as a bug to catch and fix.
