What this tool builds

Standard JSON-LD generators produce isolated code blocks. Each script tag stands alone, forcing AI crawlers to guess how your organization, services, and FAQ entries relate to each other. This tool takes a different approach.

It compiles a unified @graph array where every node, your Organization, WebSite, Service, FAQPage, and OfferCatalog, carries a stable @id URI fragment. Child nodes bind back to the parent entity using publisher, provider, and about references, forming a closed relational loop a crawler can traverse without guessing.

Topic strings you enter in knowsAbout and service specialties are converted to Schema.org Thing nodes with verified Wikipedia and Wikidata sameAs URIs. FAQ and Service nodes receive SpeakableSpecification markup with your CSS selectors, so AI voice systems and summary extractors know exactly where to pull your authoritative answers.

Who should use this

Marketing leads, technical SEO engineers, and founders who understand that AI citation authority is built at the infrastructure layer, not the content layer. If you are deploying structured data for a business that needs to appear as a cited source in Perplexity, Gemini, or SearchGPT answer surfaces, this is the tool that compiles that infrastructure.

Schema builder questions

Technical answers to the most common structured data and AEO schema questions.

What is a @graph JSON-LD structure and why does it matter for AI answer engines?
A @graph array compiles all your schema nodes into a single interconnected document. Each node has a stable @id URI fragment, and nodes reference each other directly. AI crawlers that power Perplexity, Gemini, and SearchGPT read these relational references to understand how your organization, services, and content are connected. Flat, disconnected schema scripts require crawlers to infer those relationships, which introduces extraction errors and reduces citation probability.
What is Wikidata disambiguation and why is it included?
Wikidata and Wikipedia URIs are machine-readable canonical identifiers for real-world concepts. When your schema uses a Thing node with a Wikidata sameAs URI, AI retrieval pipelines can resolve the ambiguity between, for example, your use of the word 'digital marketing' and the established concept at Q1783622 on Wikidata. This improves how confidently a model can match your brand to authoritative knowledge sources.
What does SpeakableSpecification do?
SpeakableSpecification tells AI systems which CSS selectors on your page contain the highest-value text for audio playback and summary extraction. When Perplexity or Google's SGE pulls a cited passage from your site, SpeakableSpecification acts as a direct instruction: extract text from these selectors first. Without it, the crawler selects passages using its own heuristics.
How does the Schema Health Index score work?
The score starts at 100 and deducts points for structural problems. Red alerts deduct 15 to 25 points for missing canonical URLs, invalid syntax, or broken relational references. Amber warnings deduct 4 to 10 points for missing verifiable claims, topics without Wikidata matches, or FAQ answers over 150 words. Green badges confirm valid @id linking, Wikidata disambiguation, and SpeakableSpecification presence.
Why does FAQ answer length matter for AI citation?
Retrieval-Augmented Generation pipelines slice your page content into approximately 150-word vector chunks. A FAQ answer that runs past 150 words gets split across two chunks, and neither chunk carries the complete answer. The retrieval system returns an incomplete fragment as a citation. Keeping answers under 150 words keeps each answer inside a single vector chunk and maximizes citation completeness.
Can I import data from the Semantic Entity Grader?
Yes. Append ?brand=YourBrand&url=https://yoursite.com&topics=SEO,Digital+Marketing to the URL when arriving from another tool. The builder reads those parameters on load and pre-fills the corresponding fields. This creates a direct bridge between your entity audit results and your schema compilation workflow.

How the AEO Knowledge Graph and Schema Builder works

Most schema generators produce flat, disconnected JSON-LD scripts. This tool compiles a unified @graph array where every node carries a stable @id URI and references its related nodes directly. The result is a closed relational knowledge graph that AI crawlers can traverse, not a collection of isolated markup fragments.

  1. Enter your Entity Core: brand name, canonical URL, logo, and authority links. These inputs define the root Organization or LocalBusiness node with stable @id referencing and sameAs URI disambiguation.
  2. Add your service name, description, area served, pricing model, starting price, SLA, and warranty terms. These map to a Service node with an OfferCatalog and QuantitativeValue structure. AI answer engines surface verifiable pricing and delivery data as a trust signal.
  3. Build your FAQ entries and set your Speakable CSS selectors. FAQ answers compile to a FAQPage node with SpeakableSpecification markup, which tells AI voice systems and summary extractors which page selectors contain your authoritative answers.
  4. Review the live Schema Health Index score and diagnostic badges. Resolve any red alerts and amber warnings before copying the output. The score reflects real extraction probability, not cosmetic completeness.

Why standard schema builders fail in 2026

Most online schema generators produce one script tag per node type: one for Organization, a separate one for FAQPage, another for Service. Each script is valid JSON-LD on its own, but they are disconnected fragments. AI crawlers using Retrieval-Augmented Generation slice your page into 150-word vector chunks and embed each chunk independently. A disconnected FAQPage script has no machine-readable path back to your Organization node. The crawler must guess the relationship, and guesses reduce citation confidence.

Wikidata disambiguation is the difference between a brand claiming expertise in 'digital marketing' and a brand whose schema points to the verified, machine-readable concept at Wikidata Q1783622. AI retrieval systems score document relevance against these canonical concept identifiers. Without the URI, your claim is a string. With it, your claim is a verified assertion tied to the global knowledge graph.

SpeakableSpecification is consistently omitted from every automated schema tool we have audited. This markup tells AI voice and summary systems exactly where your highest-authority text lives on the page. Without it, AI systems apply their own heuristics to select citation passages. Those heuristics frequently select header text, navigation copy, or footer disclaimers instead of your core service claims.

Our engineering difference

This tool compiles a single @graph array where every node, Organization, WebSite, Service, FAQPage, and OfferCatalog, carries a stable @id URI fragment anchored to your canonical domain. The Organization node is the root. Every other node references it through publisher, provider, or about bindings. The result is a closed relational loop: a crawler that follows any node in the graph can reach all other nodes without inference.

Topic strings you enter in knowsAbout and service specialties are converted to Schema.org Thing nodes with Wikipedia and Wikidata sameAs URIs from a curated dictionary. When no match is found, the linter flags it as an amber warning so you can either correct the spelling or accept the unresolved string.

The Schema Health Index is a deterministic scoring system, not a checklist. It starts at 100 and deducts points for structural problems in order of severity. Missing canonical URL costs 20 points. Missing Wikidata matches cost 3 points each. FAQ answers over 150 words cost 4 points each. The score reflects how likely an AI retrieval pipeline is to extract and cite your content correctly, not whether the JSON is syntactically valid.

Who this AEO schema builder is for

Marketing leads, technical SEO engineers, and founders who understand that AI citation authority is built at the infrastructure layer, not the content layer. If you are deploying structured data for a business that needs to appear as a cited source in Perplexity, Gemini, or SearchGPT answer surfaces, this is the tool that compiles that infrastructure.
