## What you need to know

### How should ecommerce structured data be preserved?

Inventory each structured-data type and rebuild it from the new page’s visible facts and stable identifiers. Validate rendered markup against current search requirements before and after launch.

### How should Product structured data be validated?

Check that Product markup describes the visible product and includes valid identifiers, names, images and applicable properties. Test representative simple, variant and unavailable products on the rendered page.

### How should Offer data be validated after migration?

Compare Offer price, currency, availability, condition and seller data with the visible purchasable offer. Test changes in stock and price to confirm markup updates with the page.

### How should Breadcrumb structured data be migrated?

Generate Breadcrumb markup from the approved visible hierarchy and final URLs. Confirm every breadcrumb item is ordered correctly and resolves without a redirect or error.

### Why did rich search results disappear after migration?

Rich results can disappear when markup is missing, invalid, inconsistent with visible content or no longer eligible. Validate the rendered data and page first; eligibility never guarantees that a rich result will display.

### A quick store check

Validate rendered structured data for an available product, an unavailable product and a variant product against visible page facts.

## Frequently asked questions

### Does valid structured data guarantee a rich result?

No. Validity and eligibility do not guarantee that a search engine will display an enhancement.

### Should old markup be copied unchanged?

No. Rebuild it from the new page and current specification because templates and eligibility can change.
