How does entity optimization differ from traditional SEO?

Traditional SEO and entity optimization aim at different targets, which is why they use different tools. SEO works to rank specific pages for specific keyword queries, largely through on-page content, links, and technical signals. Entity optimization works to make Google’s Knowledge Graph and the AI engines recognize a brand or person as a distinct identity and describe it accurately, which is a different problem with a different toolkit. Instead of optimizing a page for a phrase, the work builds and aligns the signals that define the entity: schema markup on owned properties, an accurate Wikidata entry, Wikipedia where notability supports it, consistent descriptions across authoritative profiles, and sameAs links that tie the references together. The reason this has moved to the center of reputation work is that AI engines reason about entities, not keywords, and a Knowledge Panel is generated from entity confidence, not page ranking. We treat this as the entity layer of a program, distinct from and increasingly more important than classic keyword SEO.
