Entity & Topical Authority Mapper for Car Dealers — AI Citation Score

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.

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.

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.

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.

You cannot outrank aggregators for broad inventory searches, but you can dominate brand-specific local queries. Create model landing pages targeting "[make] [model] for sale in [city]." Add unique descriptions and photos for featured vehicles. Build local authority through community content and sponsorship mentions. Focus on the local pack where proximity gives you an advantage aggregators lack.

Use dynamic inventory pages with Vehicle schema that updates automatically as stock changes. Keep sold vehicle URLs active briefly with a redirect to similar available vehicles rather than returning 404 errors. Create evergreen model pages that persist regardless of current inventory. Submit an XML sitemap that refreshes daily to ensure Google always sees your current stock.
