Knowledge graph
What is a knowledge graph?
A knowledge graph is a structured network of real-world entities, such as people, companies, places, products and concepts, linked by named relationships. Instead of storing text as strings of words, it stores facts: "BeBranded is a digital agency", "the agency offers SEO services". Search engines and AI systems use these connections to understand what a query is about, not only which words it contains.
Google's Knowledge Graph, launched in 2012 under the slogan "things, not strings", is the best-known example. It powers knowledge panels, entity cards and many direct answers on the results page.
How a knowledge graph works
A knowledge graph is built from three elements: entities (the nodes), attributes (facts about each node) and relationships (the links between nodes). Each fact is often expressed as a triple: subject, predicate, object.
- Subject: the entity described, for example a company.
- Predicate: the relationship, for example "founded by" or "located in".
- Object: the value or the linked entity, for example a person or a city.
Sources feed the graph: structured databases, Wikipedia and Wikidata, official websites and structured data published on pages. The system reconciles them, resolves duplicates and assigns each entity a unique identifier.
Why it matters for SEO and GEO
When a search engine recognises your brand as a distinct entity, it can show a knowledge panel, connect you with the right topics and trust the facts you publish. For generative engines, entity clarity helps answers cite the right company, product or author. This is a core idea behind generative engine optimization and E-E-A-T: being a known, consistent and verifiable entity.
The effect shows on the SERP through knowledge panels, rich results and AI Overviews that name sources.
Knowledge graph vs database vs schema markup
| Concept | What it is | Role in SEO |
|---|---|---|
| Knowledge graph | Network of entities and relationships | Lets engines understand and connect facts |
| Database | Tables of records for an application | Stores your own data, invisible to search engines |
| Schema markup | Vocabulary added to page code | Feeds entity facts into the graph |
Schema markup is one input, the knowledge graph is the resulting understanding. You do not edit Google's graph directly: you send consistent signals and let the engine reconcile them.
How to feed a knowledge graph
- Publish consistent facts about your organisation (name, logo, address, founders, social profiles) on your website and external profiles.
- Add schema markup such as Organization, Person and Product, with
sameAslinks to trusted profiles. - Create or update entries in reference sources like Wikidata when you meet their notability rules.
- Build an About page and author pages that state who you are and what you are expert in.
- Earn mentions on reliable third-party sites that describe you the same way.
Example of a minimal markup:
{"@type":"Organization","name":"BeBranded","url":"https://www.bebranded.xyz","sameAs":["https://www.linkedin.com/company/bebranded"]}
Inconsistent names or conflicting facts across sources are the main reason an entity is not recognised. Results are never guaranteed, since inclusion is decided by the engine.
