SERP and Entities
Knowledge Graph Search
Search Google's public Knowledge Graph for an entity and see its identifier, types, description and source, straight from the official API.
- Uses an official API
- Keys stay on our server
The tool
Enter the name of an entity, such as a company or a person. Results come from Google's Knowledge Graph API.
Loading the tool…
Your query is sent from our server to the provider named on this page, using our API credentials, and the provider response is shown to you. We do not store the query or the results. The provider handles the request under its own terms and privacy policy.
What this tool checks
- Whether an entity exists in Google's public Knowledge Graph for a name
- Its identifier (a kg:/m/ or kg:/g/ machine ID)
- The schema.org types it is classified under
- Its short description and detailed description, with source and licence
- Its official website and image, when the graph has them
- The relative result score for each match
How to read the results
- Find the result that is really your entity. Several entities can share a name.
- Note its identifier. You can link to it from sameAs in your structured data and open it in Google.
- Check the types and description are accurate. If they are not, improve the public sources Google relies on.
- Compare scores only within one search. They are relative, not a measure of authority.
About this tool
What the Knowledge Graph is
Google’s Knowledge Graph is a database of entities, the people, organisations, places, products and ideas that things on the web are about, and the facts that connect them. It powers knowledge panels and helps Google understand which “Mercury” or “Jaguar” a page means. Each entity has a stable machine identifier such as kg:/m/0dl567, a set of types and usually a short description.
This tool queries the public part of that graph through Google’s official APIs and shows what comes back. It is a practical way to answer questions like “does Google recognise our company as an entity?”, “which ID should our structured data point to?” and “how is this person described?”.
Which API we use
Google offers two ways in. The Knowledge Graph Search API is the original, simple one, but Google’s documentation now says it is not suitable as a production-critical service and directs new users to the Enterprise Knowledge Graph product in Google Cloud. We follow that advice: if the site owner has configured Enterprise Knowledge Graph, it is used; otherwise the legacy API is used as a fallback, and every result says which one answered. Credentials stay on our server.
Reading the results
- Name and types. Types use schema.org names such as Organization, Person, Place or Corporation. An entity with only the generic Thing type is known but not well classified.
- Description. A short label, such as “Software company”, plus a longer passage that usually comes from a public source like Wikipedia. The source link and licence are shown so you can check and attribute it.
- Identifier. The machine ID. Open it in Google to see the entity Google associates with it.
- Result score. How well the entity matched this query compared with the other results. It is not a measure of importance and changes from query to query.
Using the identifier in structured data
Structured data on your site can connect your organisation or a person to the entity Google already knows. List authoritative profiles in the sameAs property of your Organization or Person markup, such as your Wikipedia, Wikidata, LinkedIn and official social profiles. Consistent names, addresses and descriptions across those sources make it easier for search engines to tie them together. The Schema Markup Generator can produce that markup.
If your entity is missing or wrong
There is no form to submit an entity to the Knowledge Graph. Google builds it from public sources it trusts. Clear, consistent information about who you are on your own site, in structured data and on reputable third-party sources is what helps. If you already have a knowledge panel, Google lets the entity it describes claim it and suggest changes through Search.
What happens to your data
Your query is sent from our server to Google and the response is shown to you. We do not store the query or the results. Exports are created in your browser.
Limits and honest caveats
- Needs credentials configured by the site owner: a Google Cloud Enterprise Knowledge Graph project or, as a fallback, a legacy Knowledge Graph Search API key.
- Google says the legacy Search API is not suitable as a production-critical service and recommends Enterprise Knowledge Graph for new users.
- The API returns a subset of public graph data. It does not show everything Google knows or how it uses it in search features.
- Not appearing does not mean Google has no information about an entity, and appearing does not guarantee a knowledge panel.
- Result scores are relative within a single query and cannot be compared across searches.
Google Cloud Enterprise Knowledge Graph — Preferred. Your query is sent from our server to Google using a service account owned by the site. Billed and rate-limited under the site's Google Cloud project.
Knowledge Graph Search API (legacy) — Fallback when Enterprise Knowledge Graph is not configured. The query is sent with the site's API key. Results are labelled with the source used.
What people use it for
- Checking whether Google recognises a company or person as an entity
- Finding the identifier to reference in structured data and sameAs links
- Seeing how an entity is described and which source the description comes from
- Telling apart entities that share a name
- Auditing entity types before writing Organization or Person markup
Questions
Questions about this tool
The things clients actually want to know — costs, timelines, ownership and what happens after launch.
The public graph only includes entities Google has enough trusted information about, and the API returns a subset of it. Consistent information on your site, in structured data and on reputable sources helps over time.
A relative measure of how well each entity matched this query. It is not a quality or authority score and cannot be compared between searches.
No. Knowledge panels are a search feature with their own logic. This tool only shows public graph data from the API.
Enterprise Knowledge Graph when the site owner has configured it, as Google recommends, and otherwise the legacy Knowledge Graph Search API. Each result is labelled with its source.
Not directly. If there is a knowledge panel, the entity it describes can claim it and suggest changes. Otherwise, improve the public sources Google relies on.
