As an SEO & GEO expert and CEO & Head of SEO at SUMAX, I position your brand as an entity in the Knowledge Graph: entity audit, Wikidata, Schema @id graph, sameAs cluster, author entity. The foundation on which AI Overviews, ChatGPT, Perplexity and Gemini cite your brand consistently. Setup protocol: 90 days.
“Keywords are interchangeable. Entities are not.”
If one layer is weak, the entity stays below the confidence threshold, however strong the other two are. Entity SEO works on all three at once.
Wikidata QID, Schema.org @id, canonical URL, a stable brand name. To a machine, the entity must be one unambiguous node, not a keyword many documents share.
A curated sameAs cluster of 7–10 strong identity profiles. Identical contact data, photo and role description. Press articles are sources about the entity (subjectOf), not sameAs identities. Every deviation weakens coherence.
Independent secondary sources (trade media, industry publications, research citations) confirm the entity's attributes. Without them, the entity remains a brand claim, not a fact.
Three phases, each closing with an artefact you can check.
Days 1-30: Knowledge Graph presence, name-collision matrix, Wikidata status, Schema inventory, sameAs maturity. Outcome: diagnostic report and disambiguation strategy.
Days 31-60: entity home on the primary domain, Schema.org JSON-LD with @id coherence, a referenced Wikidata item (only after a passed eligibility check), curated sameAs cluster, author entity setup.
Days 61-90: press briefing, 3-5 authoritative secondary sources with consistent facts, Knowledge Graph API monitoring, entity drift tracking.
Six metrics tracked weekly, from Wikidata statements to LLM entity resolution.
Documented status across all three layers, gaps included.
Eligibility check first (notability, sources), then the item with referenced properties, external IDs and multilingual labels. Knowledge bases are not marketing directories.
Production-ready markup for Person, Organization, Article and Product, linked via @id.
7–10 strong profiles with identical attributes. Curated, not mass-produced.
Bio templates, credential provenance, Schema author blocks for E-E-A-T.
Quarterly Knowledge Graph check, Wikidata watchlist, LLM resolution tracking.
Entity SEO is the structural discipline of establishing a brand, a person or a product as one unambiguous node in Google's Knowledge Graph, and of keeping that node consistent in Wikidata, in Schema.org markup, across sameAs profiles and in the embedding space of large language models. An entity is a clearly identifiable concept with attributes, relationships and external references. In Wikidata it corresponds to a QID, in Schema.org to an @id and in the Knowledge Graph Search API to a machine ID (MID). The work runs on three layers at once: identifiability (unique node IDs, canonical URL, stable name), consistency (name, photo, role and affiliation identical across every sameAs profile) and corroboration (authoritative secondary sources confirming the entity's attributes). Search engines and AI assistants resolve the entities in a query before they compose an answer, so a brand without a clean entity node is hard for them to name correctly.
A complete Wikidata item typically carries multilingual labels, 20 to 40 referenced statements and identifiers such as ORCID, ISNI, GND or VIAF. Schema.org bridges your CMS and the Knowledge Graph, with @id coherence across the whole domain. The Knowledge Panel is not the goal but the visible trust signal of a stable entity node, and whether it appears is Google's decision.
QID, @id, a canonical entity home and a stable brand name: one unambiguous node.
7–10 strong profiles with identical data, photo and role. Every deviation weakens coherence and makes a panel less likely.
At least three authoritative secondary sources confirm the core attributes.
Quarterly Wikidata watchlist, sameAs drift monitoring, Schema validation after every CMS release, updates when roles change.
Four documented steps in a fixed order. A Wikidata item created without an audit risks failing notability; Schema links without a stable item leave the entity unanchored.
Knowledge Graph API queries, name-collision matrix, Wikidata status, Schema inventory, sameAs maturity score. Result: a diagnosis report with concrete gaps and a disambiguation strategy.
Eligibility check first: do notability and sources support an item? Only then do we create it, with referenced properties, multilingual labels and external identifiers (ORCID, ISNI, GND, VIAF). If the base is missing, corroboration comes first. Result: a referenced item, or an honest roadmap towards one.
A complete JSON-LD @id graph on the entity home across all templates, sameAs to the QID where an item exists, author blocks for E-E-A-T, Schema Markup Validator run.
Press briefing for three to five secondary sources, panel tracking for brand queries, Wikidata watchlist, LLM resolution test across GPT, Claude, Gemini and Perplexity. Result: a measurable Knowledge Graph presence.
Entity SEO does not replace the classic disciplines; it lays the foundation they rely on. The right mix depends on your brand's maturity.
Entity SEO pays off wherever search engines and LLMs must resolve an identity correctly before they can answer at all.
Founder, CEO, author or speaker as a Person entity with Wikidata item where eligible, ORCID and author Schema. A lever for E-E-A-T and LLM citations in YMYL and advisory sectors.
Product or SoftwareApplication markup, listings on G2, Capterra and Crunchbase, pricing and rating data. A prerequisite for appearing in AI comparison answers.
An established brand without a Knowledge Panel, a classic symptom of unstructured entity substance. Groundwork: Organization graph, sameAs consolidation, press corroboration.
Holdings with brands, sub-brands and joint ventures. Hierarchy via parentOrganization and subOrganization, disambiguation against spin-offs and legacy names.
Branches, showrooms and practices as LocalBusiness entities with geo properties, a linked Business Profile and consistent contact data. The basis for local panels and Maps.
MedicalEntity, Drug and Physician entities with licensing references and MLR-compliant author provenance. Entity clarity as the YMYL trust layer for AI health answers.
The investment depends on entity maturity, the number of entities and the corroboration needed. Every model delivers documented artefacts that you own after the engagement ends. Exact terms are set in the scope call.
3 to 4 weeks. Diagnostic report with a prioritized roadmap.

Entity SEO shifts optimization from the keyword to the node in the Knowledge Graph. An entity is a clearly identifiable person, organization, product, place or idea with attributes, relationships and references. The work covers identifiability (QID, @id), consistency (sameAs, contact data) and corroboration (authoritative third-party mentions).
Classic SEO optimizes documents for keywords. Entity SEO optimizes nodes in the Knowledge Graph. In LLM-driven search, entity work is the primary lever, because generative systems resolve the entities in a query before they generate an answer.
No. Wikidata is the primary lever. Its notability policy differs from Wikipedia's but still requires serious, public references, so we check eligibility first. Wikipedia adds corroboration once its own criteria are met. In our projects, around 80 percent do not need it.
The 90-day protocol lays the foundation. Measurable effects on LLM resolution and Knowledge Graph visibility typically show after three to nine months. If a Knowledge Panel appears, it usually does so after six to twelve months; whether it appears is Google's decision.
It is Google's visible representation of an entity, in the desktop sidebar or as a mobile card. You cannot apply for one. It appears as a by-product of a stable entity: a referenced Wikidata item, a coherent Schema graph, a consistent sameAs cluster and at least three authoritative secondary sources.
Distinct signals decide: a consistent image, a distinct profession property, distinct sameAs profiles and distinct co-occurrence (affiliation, geography). The name-collision matrix in the audit lists every namesake and defines a set of distinguishing attributes that is kept consistent everywhere.
Links from the entity home to profiles with identical name, photo, role and affiliation: LinkedIn, Wikidata, Crunchbase, GitHub, YouTube, industry directories, conference and author profiles. A wider footprint may span 15 to 25 profiles; only the 7–10 strongest belong in sameAs. Press coverage goes into subjectOf.
Six metrics: referenced Wikidata statements, sameAs coherence, Schema graph validity, Knowledge Panel appearance for brand queries, LLM entity resolution rate (GPT, Claude, Gemini, Perplexity) and citation rate in AI Overviews. We measure quarterly.
AI Overviews, ChatGPT, Perplexity, Gemini and Claude first identify the entities a question refers to, then generate the answer. A brand that cannot be resolved unambiguously is often missing or confused with others, even with flawless classic SEO.
Sectors with high trust needs and real risk of name confusion: healthcare and pharma, financial services, B2B SaaS with several products, multi-brand groups, and personal brands in consulting and public speaking.
Brand SEO targets brand queries and brand SERP real estate (sitelinks, reviews, brand box). Entity SEO works one level deeper, on the machine-readable identity node. Brand SEO is the visible result, entity SEO the foundation, and without it brand SEO breaks down when names are shared.
