Yoast SEO’s New Schema Aggregator Improves Entity Disambiguation

Yoast announced a new Schema Aggregation feature that locates your site’s entire structured data in one location. The integration enables WordPress sites that use Yoast’s plugin to make website content more readable and usable to AI systems.

Coherent Entity Disambiguation

The new Schema Aggregation feature makes relationships between entities on a site easier for AI systems to understand. Instead of returning structured data separately on each page, the schemamap connects entities across the site and removes duplicate records.

Authors remain linked to the articles they publish, and organizations remain linked to their content and products. This structure allows AI systems to retrieve structured data that already contains the relationships between entities rather than reconstructing them by crawling pages individually.

Yoast explains:

“Complete: All indexable content included

• Clean: No duplicate entities, no navigation clutter
• Connected: Relationships between entities preserved (author → articles)
• Compliant: Respects exisiting privacy settings
• Fast: Sub-100ms cached responses, pagination for large sites”

The opt-in feature, available in Yoast SEO 27.1, adds an endpoint that returns a website’s structured data as a single output called a schemamap.

The feature provides a consolidated representation of a site’s schema.org structured data instead of forcing AI crawlers and agents to download it page by page. AI systems can retrieve the site’s schema graph through the endpoint. The response contains structured data that describes articles, authors, products, and organizations and maintains the relationships between those entities.

Yoast’s SEO plugin already outputs structured data. But this new feature is able to bring it all together in one place.

Alex Moss, Principal SEO at Yoast explained:

“…We’re introducing the Schema Aggregation feature: a “schemamap” endpoint that outputs your site’s entire structured data map in one place.
​
Under the hood, we now provide a standardised, deduplicated map of your entities via a single endpoint. An agent no longer needs to crawl all individual pages to understand its meaning but can now ingest an entire entity map with ease.”

Moss also offered technical details:

“A few details to note about the endpoint:

• It’s is cacheable with sub‑100ms responses
• It respects existing privacy and indexing settings
• It aggregates all indexable content without navigation noise
• It merges duplicate entities so your “Author X” or “Article Y” exist as a single node instead of being re‑discovered on every URL.
• If you’re using one of our paid plugins that extends schema even more (such as Yoast WooCommerce SEO adds product schema) this will be populated within the endpoint too
• If you already extend Yoast’s Schema API, or use partners like events or recipe plugins, their entities are pulled into the same map automatically.

For me, this is one of the first major ways the agentic…
