The 6 topical authority factors explained
Content depth (800+ words)
Comprehensive content is the first signal AI systems use to assess authority. Pages under 500 words rarely achieve strong topical authority. The threshold is 800+ words for most topics, 1200+ for competitive ones.
Topic & entity coverage
Entity density and diversity tell AI systems whether a page covers a topic broadly enough to be trustworthy. Aim for 8+ distinct entities related to your main topic, across at least 3 entity types.
Content structure
Structured content (headings + clear paragraphs) is easier for AI extraction algorithms to parse. Well-structured pages are cited 4× more often than unformatted text dumps.
Definitions & explanations
AI systems favour definitional sentences ("X is a...", "X refers to..."). These are the most commonly extracted passage types for knowledge-panel and citation answers.
Data & statistics
Pages that include verifiable statistics and research citations are perceived as more authoritative. Even rough benchmarks ("studies show X%...") improve citation rate.
FAQ & question signals
Pages with embedded questions and direct answers win disproportionate PAA, featured snippet, and AI cite slots. Two or more questions significantly improve the GEO score.
Why entity optimisation matters for AI search
Google runs on entities, not keywords
Google's Knowledge Graph stores billions of entities and relationships. When your content covers the right entities, Google can confidently associate your page with a topic - leading to higher rankings independently of exact keyword density.
AI models cite entity-rich content
ChatGPT, Perplexity, and Google AI Overviews preferentially cite pages that clearly define concepts, reference specific organisations and products, and connect entities with verified relationships. Thin content with limited entity coverage is consistently ignored.
Entity diversity beats repetition
A page mentioning five different entity types (concept + product + organisation + person + event) signals broader expertise than 50 mentions of a single keyword. The scoring system rewards entity type diversity explicitly.

Frequently asked questions
What is topical authority in SEO?
Topical authority is a measure of how comprehensively a page - and the site it sits on - covers a subject. Google and AI systems assess it by evaluating the entity density, topic depth, and structural quality of content. High topical authority leads to more consistent rankings and AI citations.
What are entities in SEO?
Entities are distinct things: people, places, organisations, products, concepts, and events. Google's Knowledge Graph is entity-based rather than keyword-based. Mentioning and properly explaining entities in your content builds Google's confidence in your expertise on a topic.
How does this tool detect entities?
The tool uses n-gram extraction and heuristic classification to identify noun phrases, proper nouns, and recurring key terms. It then classifies them by type (concept, product, organisation, person, place, event) and measures frequency. All analysis is client-side - your content never leaves your browser.
How many entities should a page have?
8+ entities is a reasonable baseline, 12-20 is strong, and 20+ across multiple types signals comprehensive coverage. Entity diversity (multiple types) matters as much as count - covering concepts + organisations + people signals multi-angle expertise.
Does this tool send my content to a server?
No. All analysis runs locally in your browser using JavaScript. Nothing is uploaded or stored.
