Entity SEO
Entity SEO is the practice of making the people, organizations, and concepts on a site unambiguously identifiable to machines — through consistent naming, structured data, and links to authoritative profiles. Search and answer engines reason over entities, not keywords, so an unresolved entity cannot be credited, cited, or trusted.
Machines resolve entities before they judge content
Before a system decides whether a passage is authoritative, it decides who said it. If the author string appears in three spellings, has no Person schema, and links to nothing external, the entity does not resolve — and the content inherits the credibility of an anonymous page.
The minimum entity kit
Every claim-bearing site should publish an author hub per expert and an organization node, then reference them consistently from every article.
- —Person schema with jobTitle, knowsAbout, affiliation, and sameAs links.
- —One canonical author hub URL per expert, linked from every byline.
- —Organization schema on the root with a stable @id other nodes reference.
- —Identical name spelling and credential phrasing everywhere.
How an entity actually resolves
A machine resolving 'Aaron Bare' is running a disambiguation loop: it collects every mention, clusters the ones that co-occur with the same attributes — job title, affiliations, topics, publications — and decides whether they describe one person or several. Your job is to make that clustering trivial by repeating the same attributes in the same words everywhere the name appears.
The moment a bio says 'strategist' on one page, 'facilitator' on another, and 'author' on a third, with no shared anchor, the cluster fragments and the credibility that should accrue to one entity is split across three ghosts.
A concrete implementation checklist
Entity work is finite. Most sites can complete it in a week and never revisit it except to add new experts.
- —Publish one author hub per expert at a stable URL and never move it.
- —Emit Person schema with name, jobTitle, knowsAbout, affiliation, url, image, and sameAs.
- —Emit Organization schema once on the root with a stable @id, then reference that @id from every Article.
- —Set author on every Article to the Person @id, not to a bare string.
- —Link the author hub from every byline and from the footer.
- —Mirror the same bio sentence on external profiles so sameAs targets corroborate rather than contradict.
Entities for concepts, not just people
Named methods behave like entities too. A framework with a consistent name, a canonical definition page, and repeated use across essays becomes something a model can attribute. A framework described differently every time it appears stays an unnamed idea that gets credited to whoever named theirs first.
Frequently asked
- What is sameAs used for?
- sameAs links an entity on your site to its representations elsewhere — Wikipedia, LinkedIn, Crunchbase, publisher pages — so a machine can confirm they describe the same person or organization.
- Does entity SEO help with AI citations?
- Substantially. Answer engines prefer sources whose authorship and expertise they can verify, because attributing an answer to an unresolvable entity is a risk they are tuned to avoid.

Generative Engine Optimization
Generative Engine Optimization (GEO) is the practice of influencing what a generative model says about a topic, brand, or person — through the sources it retrieves and the training corpus it absorbed. AEO targets a single extractable answer; GEO targets the model's overall representation of you.
Answer Engine Optimization
Answer Engine Optimization (AEO) is the practice of structuring content so answer engines — ChatGPT, Google AI Overviews, Perplexity, Claude, and Copilot — can extract, cite, and reuse it as the answer to a question. Where SEO competes for a click on a ranked link, AEO competes to be the sentence the machine says out loud.
Citation Share
Citation share is the percentage of AI-generated answers to a defined set of questions in which a given domain appears as a cited source. It is the primary scoreboard for answer engine optimization, replacing keyword rank as the measure of visibility when the answer, not the link, is the destination.
