Schema Markup Validator
Checks Schema.org syntax
Validates that your JSON-LD is well-formed and uses valid Schema.org vocabulary. It does not tell you whether Google will show a rich result.
Use it: while writing markupTest any Squarespace page for schema markup, structured data validation, rich result eligibility, and JSON-LD errors. Built for the auto schema Squarespace outputs and custom Code Injection markup.
This is an illustrative preview of how an audit reads. Connect your store to JSON Schema App to validate the live page and auto-fix every error found.
Fix these in JSON Schema AppThe audit reads each block of JSON-LD on your Squarespace page, including the schema Squarespace generates automatically, maps it to its Schema.org type, and flags the required and recommended properties Google looks for.
Price, availability, rating, and review count that unlock product rich results and merchant listings for your Squarespace Commerce items.
Squarespace does not output these automatically, so add them via Code Injection to expand your listing and feed AI overviews with structured answers.
Headline, author, and publish date that qualify your Squarespace blog posts for Top Stories and article enhancements.
The navigation trail Google shows in place of a raw URL, giving searchers instant context about the page.
Site-wide logo, social profiles, and contact data you add through Header Code Injection to build the knowledge panel.
Star ratings and aggregate scores that make listings stand out and lift click-through from the SERP.
Three steps, no learning curve. Run the check, read the report, then fix what matters most for rich-result eligibility.
Drop in any product, blog post, or page. The tool fetches the live page and reads its structured data the way a search crawler does, including the auto schema Squarespace generates.
See each detected type with a clear status: valid, missing a recommended property, or carrying an error. Every flag links to the exact Schema.org rule behind it, so nothing is a mystery.
Add or correct JSON-LD in Settings, Advanced, Code Injection, or let JSON Schema App generate compliant JSON-LD across your site. Re-run the audit to confirm a clean pass.
Most rich-result problems come down to a handful of recurring issues. Here is what each one means, how serious it is, and the fix.
A field Google requires is absent, so the whole block is ineligible. For an auto Article block this is often a missing image or dateModified. Add the required field and re-check.
The property exists but the data is malformed: an empty string, a wrong data type, or a date that is not in ISO 8601. Use values that match the Schema.org spec exactly.
The same type is declared twice, often by the schema Squarespace outputs automatically plus a custom block you added in Code Injection. Conflicting data lowers crawler trust. Keep a single source of truth per type.
The markup uses a type Google does not surface as a rich result, or the wrong type for the page (Product markup on a regular page). Match the type to the content.
The markup describes data a visitor cannot see, or a price that no longer matches the page because the auto schema is cached. Mark up only visible content and sync dynamic values.
A missing comma, bracket, or quote in your Code Injection breaks the entire block so nothing is read. Check the JSON-LD structure and that properties are nested under the right parent.
Valid markup makes a page eligible for rich results. It does not force them to appear. When they don't, it is usually one of these.
Google can only show a rich result for a page in its index. Confirm the URL is indexed in Search Console before assuming the markup is the problem.
Google no longer shows review stars for reviews a business writes about itself. Ratings need to come from genuine, independent reviews rather than values hard-coded in your markup.
If the schema describes a price, rating, or text a visitor cannot see, or a value that is cached and stale, Google withholds the rich result. Keep markup and visible content in sync.
Not every Schema.org type produces a rich result, and Google occasionally retires features. Check that the type still maps to a supported result before troubleshooting further.
After a fix, Google has to re-crawl and re-process the page. Rich results can take days to reappear, so re-check, then give it time rather than changing things again.
Structured data is not a direct ranking factor. What it does is make your content machine-readable, so search engines and AI assistants can understand a Squarespace page well enough to enhance how it appears. That often means a richer listing, a higher click-through rate, and a better shot at being cited in AI answers.
Backlinko's analysis of millions of results found that pages with structured data tend to earn more visibility from rich features. Squarespace outputs basic schema for blog posts, products, and events automatically, but you cannot edit it and it is sparse, with no FAQ or How-To and limited properties. This audit exists to surface those gaps before they cost you.

They are not interchangeable. Each catches a different class of problem, which is why markup can pass one and fail another. Here is what each does.
Checks Schema.org syntax
Validates that your JSON-LD is well-formed and uses valid Schema.org vocabulary. It does not tell you whether Google will show a rich result.
Use it: while writing markupChecks Google eligibility
Tests your markup against Google's feature requirements and previews how the result may look. This is why clean Schema.org can still throw errors here.
Use it: before you publishChecks live issues at scale
Reports structured data issues across your whole site from real crawls, and flags problems after pages go live. Best for monitoring, not first-pass validation.
Use it: after launch, site-wideRun a free check on any Squarespace URL, then let JSON Schema App generate and maintain valid JSON-LD across your entire site automatically.
