For SEO and AIO teams - verified-record-first SEO

AI agents can only recommend what they can verify.

Central builds a verified product record, then exposes it as Schema.org Product, FAQPage, AggregateRating, JSON-LD, x-central provenance metadata, and AI-readable feeds — so ChatGPT Shopping, Perplexity, Google AI Mode, and Bing Generative Search can answer with grounded facts instead of guesses.

AI surface coverage

The same SKU, asked of four AI agents.

Without a verified record, AI shopping engines either skip your product, hallucinate a spec, or quote a retailer that drifted from the brand record. With one, they answer the same way — and they cite your record.

Central runs the same buyer question against ChatGPT Shopping, Perplexity, Google AI Mode, and Bing Generative Search. Every answer gets graded against the verified record and the Schema.org payload behind it.

Grounded answers across every AI surface. Same record. Same fact. Same citation.

how grounded AI answers ship

Build the record. Structure the markup. Ground the agents.

AI drafts the content. Verification decides what ships. Three visible steps from a product page to a Schema.org-grounded record that AI shopping surfaces can quote.

1build the verified record

Verify every fact from 10-20 sources before any markup ships.

Brand spec sheets, retailer pages, marketplace listings, regulatory feeds. Central scores agreement, holds unsupported claims, and never lets unverified facts enter copy, FAQ, or schema.

AI agent answer testing - the same SKU across four engines

Ask the same buyer question to ChatGPT Shopping, Perplexity, Google AI Mode, and Bing Generative. Without Central: hallucination or a shrug. With Central: every agent cites the verified record.

PainYou can't see what AI agents say about your product, so you can't fix what's wrong.

x-central provenance metadata - sources and confidence in the payload

Every claim ships with a Central-owned metadata block: what the source is, how many agree, what the confidence is, and when it was last verified. Agents can prefer cited claims over guessed ones.

PainJSON-LD says a number. AI engines can't tell whether it's brand-verified or guessed from one retailer.
Valuex-central provenance blocks attach source list, agreement count, confidence, and timestamp - so any agent reading the payload can prefer verified facts.

Smart Negatives - what the AI must not claim

When a claim isn't supported by the record, Central blocks it from page copy, FAQ, schema, and the agent feed - and surfaces it for review.

PainAI invents limits or compatibility claims that nobody supports. They leak into FAQ and Schema.org and AI engines repeat them.
ValueUnsupported claims are held - they never enter copy, FAQ, schema, or the AI-readable feed.

Rich result coverage - per Schema.org type, validated

Each Schema.org type the page emits gets validated against Google's Rich Results spec. Failing types surface as a queue item with the missing field.

PainSome Schema.org markup ships, but Google's rich result test fails on FAQPage or AggregateRating, and nobody knows until traffic drops.
ValueCentral runs a rich result check on every type and tells you which field is missing per Schema spec - before the page goes live.

Three connected systems. One grounded record.

The same Central product system that verifies enrichment and publishes channels is what makes your product visible and citable across AI shopping surfaces.

01 - Enrichment Engine

Verifies every claim before it can land in markup.

Scans 10-20 sources, scores agreement, and holds unsupported claims out of page copy, FAQ, and JSON-LD. Each fact carries a source list and a confidence.

Frequently asked

Does Schema.org markup actually help with AI agents like ChatGPT and Perplexity?

+

Schema.org markup makes your product facts machine-readable. AI shopping engines and agent crawlers index those structured payloads alongside the page copy. Central generates Product, FAQPage, AggregateRating, and other Schema types from one verified record, plus an x-central provenance block so agents can prefer cited claims over guessed ones.

Will my product show up in ChatGPT Shopping or Perplexity?

+

No vendor can guarantee placement in any AI engine. What Central does guarantee is that when an agent does find your record, it sees verified facts with sources - so the agent can quote, cite, and recommend with confidence. Pages without grounded structured data and without provenance metadata routinely get skipped or hallucinated.

What is x-central provenance metadata?

+

A Central-defined metadata block embedded alongside Schema.org payloads. It carries the source list, agreement count, confidence, and verification timestamp for each claim. Agents that read the payload can prefer multi-sourced claims over single-retailer guesses. It's additive - your existing JSON-LD stays valid.

Does Central support llms.txt and agent-readable feeds?

+

Yes. Central publishes the verified record as a llms.txt-style agent feed and custom JSON / JSONL payloads, so AI shopping and answer engines can pull a clean, sourced, confidence-scored representation of your catalog without scraping HTML.

What about Bing Generative Search and Google AI Mode?

+

Both surface structured data and rich results from the same Schema.org markup Central generates. Channel Studio shapes the payload to each surface's spec (Bing's JsonLD recommendations, Google's rich result types), and the monitoring dashboard re-checks each surface and routes failures.

Will Central publish unsupported claims into FAQ or schema?

+

No. Smart Negatives hold unsupported, conflicting, or below-floor claims out of page copy, FAQ, Schema.org, and the agent feed until a second source agrees or a merchant approves. Confidence floor defaults to 0.85 with brand-owned values at 1.00.

Can Central help with Google Knowledge Graph or product knowledge signals?

+

Indirectly. Central produces strong structured payloads (Product, brand, gtin13, aggregateRating, Offer) that are the same signals Knowledge Graph pipelines and product-knowledge indexers depend on. Cleaner upstream data, stronger downstream signals.

Will this break our existing SEO or canonical setup?

+

No. Central layers structured data, FAQPage markup, and x-central metadata onto your existing pages. Canonical tags, titles, and URLs stay yours. The widget and the JSON-LD payload are additive; the rich result test and monitoring dashboard tell you immediately if a type stops being eligible.
