Schema Monitor
Understand exactly what structured data your website is outputting, find missing or outdated schema and generate a clear recommended baseline — without digging through source code.
Structured data shouldn't be difficult to understand.
Schema Monitor is a WordPress diagnostic tool designed to make JSON-LD and structured data easier to manage. Instead of manually searching page source code, Schema Monitor analyses your page and explains what schema exists, what may be missing and where potential problems need your attention.
It doesn't blindly rewrite your website or make changes behind the scenes. The free version is completely diagnostic, giving you the information you need to make informed decisions about your site's structured data.
See what's really happening with your schema
Scan individual WordPress pages and get a clear breakdown of the structured data being output.
Detect JSON-LD
Find JSON-LD blocks in the rendered page and see exactly which Schema.org entities are being output.
Identify Errors
Find invalid JSON, missing schema, duplicated entity types and potentially conflicting structured data.
Plain-English Explanations
Understand what Organization, WebPage, FAQPage, BreadcrumbList and other schema entities are actually there for.
Compare Recommendations
Compare the schema currently on your page against a conservative recommended baseline.
Schema Source Detection
Identify likely schema sources including Rank Math, Yoast, AIOSEO, WooCommerce, Elementor and custom implementations.
FAQ Content Checks
Compare FAQ schema against visible questions and answers to highlight structured data that may have become outdated.
More than a basic JSON validator
Schema Monitor combines technical checks with WordPress-specific context to make the results more useful.
Missing structured data
A page containing no JSON-LD is clearly highlighted rather than being incorrectly shown as having zero issues.
Invalid JSON
Detect malformed JSON-LD blocks that cannot be correctly interpreted.
Duplicate schema
Highlight repeated entity types so you can investigate whether multiple plugins or custom code are outputting the same information.
Property-level checks
Check common properties such as @id, page URL, names, canonical alignment and article publication dates.
Page-type recommendations
Get a suggested page type based on the WordPress content type, page title and URL.
See what schema should be there.
Schema Monitor doesn't just tell you what it finds. It creates a clean recommended baseline from information it can confidently identify on your WordPress site.
This may include Organization, WebSite, WebPage, BreadcrumbList, Article and visible FAQ information.
It deliberately avoids inventing information such as review ratings, addresses, prices or service details that cannot be reliably determined.
Keep your organisation details consistent
Add verified information once and Schema Monitor can use it when creating recommended structured data.
Business Details
Add your organisation name, website URL, telephone number, email address and logo.
Entity Type
Choose between general Organization data and LocalBusiness where appropriate.
Social Profiles
Add verified profile URLs for use with your organisation's sameAs structured-data references.

What does each part mean?
Schema Monitor is designed to explain structured data instead of simply throwing technical warnings at you.
Identifies the organisation responsible for the website and provides a consistent entity that other structured data can reference.
Represents the website as a whole rather than an individual page.
Describes the individual page currently being viewed, including its URL, title and relationship with the website.
Describes where the current page sits within the structure and hierarchy of the website.
Represents visible questions and answers contained on the page. Schema Monitor can compare these against the content visitors actually see.
A stable identifier that allows different schema entities to reference the same organisation, page or object consistently.
Frequently asked questions
Does Schema Monitor change my website's schema?
No. The free version is diagnostic and read-only. It scans your page, explains what it finds and generates recommendations without automatically changing your structured data.
Does Schema Monitor replace Google's Rich Results Test?
No. Schema Monitor provides WordPress-specific diagnostics, content comparison and schema explanations. Google's tools and the Schema.org validator can still be useful for specialist validation.
Does it work with Rank Math and Yoast?
Schema Monitor analyses the final HTML output of the page, so it can inspect schema created by Rank Math, Yoast, AIOSEO, WooCommerce, Elementor, themes and custom code.
Does Schema Monitor send my website content elsewhere?
The free version performs its page analysis inside WordPress and does not send your page content to an external AI service.
What is included with Schema Monitor Pro?
Pro extends the individual-page scanner with whole-site scanning, scheduled monitoring, schema change detection, alerts and reporting functionality.
