Entity SEO
Entity SEO is the practice of structuring content so the people, organisations, places, and things on a page are recognised as distinct entities — with persistent identifiers — in Google's Knowledge Graph1 and the equivalent retrieval graphs used by AI engines like ChatGPT, Perplexity, and Claude. The unit of optimisation is the entity, not the keyword.
For a Squarespace owner this matters because AI engines retrieve and cite based on entity relationships, not just keyword matches. A page that talks about "Billy Reiner" benefits from the engine knowing which Billy Reiner — the German Squarespace designer, the SquareRank founder — rather than treating the string as ambiguous.

Definition
Entity SEO is the practice of structuring content so the people, organisations, places, and things on a page are recognised as distinct entities — with persistent identifiers — in Google's Knowledge Graph and the equivalent retrieval graphs used by AI engines like ChatGPT, Perplexity, and Claude.
Entity SEO traces back to Google's 2012 launch of the Knowledge Graph, which the company framed as moving from "strings to things." Before the Knowledge Graph, a query like "Billy Reiner Squarespace" returned pages matching the string. After, Google increasingly returned results connected to the entity Billy Reiner (Q-ID, sameAs links, knowsAbout topics) regardless of exact-string match.
§02Knowledge Graph
Entities and the Knowledge Graph
An entity is something with a stable identifier. People (Wikidata Q-IDs), organisations (Q-IDs, official LinkedIn pages, official sameAs links), places (Q-IDs, lat/long, Google Maps Place IDs), things (Q-IDs, ISBNs, MPNs). Each entity has properties — date of birth, location, knowsAbout — and relationships — knows, worksFor, locatedIn — that the Knowledge Graph indexes.
Google's Knowledge Graph is the most visible consumer of entities, but it's not the only one. AI engines maintain their own internal entity representations during answer generation. When ChatGPT or Claude or Perplexity answers a question about an entity, the model is reasoning over its training data plus retrieved web content, with the entity as the anchor that connects the two.
§03Tactics
The four entity-SEO tactics
(1) Consistent naming. Use the exact same form of a name across every page and every external profile. 'Billy Reiner' everywhere — not 'Bill Reiner' on LinkedIn and 'Billy Reiner' on the website. (2) Schema with sameAs. Person and Organization JSON-LD with sameAs arrays linking to LinkedIn, Wikidata, Behance, the official Twitter/X. (3) Wikidata presence. Create a Wikidata entry once enough third-party references exist to support notability. (4) Topic-cluster authority. Pillar pages that comprehensively cover an entity's primary topics, signalling the entity's expertise to the graph.
Of these, (2) is the cheapest and most immediately effective. A founder Person schema with sameAs to LinkedIn, GitHub, Behance, Dribbble, and personal-site URLs is a 30-minute install and substantially better than nothing. (1) and (4) require ongoing editorial discipline. (3) is the slowest and most reputation-dependent — Wikidata moderators require third-party notability, which compounds over years2.
§04Squarespace
Entity SEO on Squarespace specifically
The Squarespace install is mechanical for the on-site half and editorial for the off-site half. On-site: ship Person + Organization JSON-LD via Site Header Code Injection (Business plan and above), include sameAs arrays pointing to LinkedIn and every social profile, set the founder page H1 to the canonical name spelling, ensure every Article's author byline matches. Off-site: keep external profile names identical, build third-party bylines on credible publishers, work towards a Wikidata entry over 12-18 months.
The Squarespace-specific opportunity: the platform's auto-emitted Article schema includes author as a Person object. If that Person object includes a sameAs array (which the platform doesn't emit by default but you can add via Code Injection), every article on the site reinforces the founder entity. Multiply by 50 articles over a year and the entity-graph signal compounds substantially. The full install pattern lives at Person schema for E-E-A-T.
