EAV Model

The EAV Model is a framework that describes any topic as a triple: Entity (a thematic object), Attribute (a characteristic of that object), and Value (specific data assigned to that characteristic).

The EAV Model is the foundation of the entire content strategy — if you can't extract EAV triples from an article, then from Google's algorithm perspective, the article is 'about nothing'.

For example, Entity 'Cortisol' + Attribute 'daily peak' + Value 'morning' = a ready fact for comparison with other pages in reranking. EAV connects directly to knowledge graphs (Entity = node, Attribute = edge, Value = target node).

In practice, EAV extraction tools pull triples from any article, then the Attribute Classifier divides them into UNIQUE, ROOT, and RARE, which determines text structure.

In practice, before writing an article, extract EAV triples from 5 competitors — this way you'll identify content gaps and attributes that will give you Information Gain.
