Build Schema.org product data from verified facts.

Hand-written markup repeats whatever the page says. Central builds structured product data from the verified record, so every property has sources and unproven claims stay out.

Every property comes from the verified record. 1 claim kept out of the markup.

Where structured data goes wrong today, and what changes.

Today

  • Markup copied from whatever the page says
  • Name, price and image, but none of the specs
  • Marketing claims repeated as machine-readable facts
  • Markup that falls behind when the product changes
  • Written by hand, one template at a time

With Central

  • Built from the verified record, not the page
  • Specs as properties, with sources behind them
  • Unproven claims kept out of the markup
  • A changed fact flagged everywhere it is used
  • The same facts for buyers, search engines and AI agents

How Central builds your structured data.

  1. Connect your shop

    Or paste a product URL. Central reads the product as it is.

  2. Agents verify the facts

    Every spec is researched and checked against independent sources before it becomes a property.

  3. Central builds the markup

    Brand, model and specs are mapped to Schema.org properties from the verified record.

  4. Review and use it

    Check what Central flagged, then use the structured data on your product pages.

What you get.

Markup from verified facts

Schema.org product data built from the verified record, not scraped from the page.

A source behind every property

Each property traces to a verified fact with sources and a confidence score.

No unproven claims

Claims that only one source makes stay out of your markup until your team decides.

  1. Proof

    Every property has a source.

    Open any property to see the pages that state it and whether they agree. If only one source makes a claim, it stays out of the markup.

    Instead of copying whatever the product page says into a markup template.

    3 sources agree on bowl capacity

  2. AI assistants

    AI agents read facts, not slogans.

    When a buyer asks an AI assistant for a mixer with a big bowl and enough power, the answer depends on facts it can read. Central makes sure those facts are there and proven.

Questions about structured data.

Something else on your mind? Talk to us.

Which properties does Central fill?

The product's identity, such as brand, model and color, plus the specs buyers compare, each built from verified facts.

Will structured data improve my rankings?

No one can promise rankings. Structured data makes your facts easy for search engines and AI agents to read, and Central makes sure those facts are proven.

What happens to claims on my page that have no source?

They stay out of the structured data until your team decides. The markup carries only facts the record can prove.

Does it work across my whole catalog?

Yes. One run covers your whole catalog, and each product's structured data comes from its own verified record.
