Free AEO Checker: Score Any Page for AI Answer Engines
Score any page for AEO readiness. We check speakable schema, answer-first content structure, structured data quality, data extractability, freshness, and entity authority.
AI search engines like ChatGPT, Perplexity, and Google AI Overviews do not just read your content. They extract specific data points, definitions, and structured elements. This tool scores how extractable your page is across 6 AEO categories.
What we check
Speakable Schema
Does your Article JSON-LD include SpeakableSpecification? Do the CSS selectors target real page elements?
Answer-First Structure
Single H1, valid heading hierarchy, question-format H2s, and concise definition paragraphs under each heading.
Structured Data Quality
Article completeness (author, dateModified, publisher), Organization sameAs, FAQPage, BreadcrumbList, and entity-linked knowsAbout.
Data Extractability
HTML tables, ordered lists, StatBlock data callouts, and external source citations that AI engines can directly extract.
Content Freshness
dateModified in schema, Last-Modified HTTP headers, and recency signals that affect AI re-crawl frequency.
Entity Authority
Organization sameAs links, Person credentials, DefinedTerm references, and OpenGraph/Twitter Card meta tags.
