Are you in Google’s Knowledge Graph?
“Google knows me” is not enough. What matters is whether it knows you as the same entity that Wikidata describes.
How do you check if you are in Google’s Knowledge Graph? Type your name, your brand or a kgmid from a knowledge panel. You will see what the Google Knowledge Graph Search API returns and whether Google, Wikidata and Wikipedia describe the same entity.
The tool at a glance
from Google’s Knowledge Graph per check, with type, description, kgmid and a link to the knowledge panel.
Google, Wikidata and Wikipedia. I compare identifiers, not just names.
a Wikidata item is linked to a Google result only by identifier. Similar names are shown separately.
is how long the server remembers a Google answer, so the same question is not asked over and over.
How it works
What the tool checks in Google and Wikidata
First it asks the Google Knowledge Graph Search API, the official API for finding entities in the Knowledge Graph. For each entity Google returns an identifier (kgmid, e.g. /g/11md2bpb8_), schema.org types, a short description, a score and sometimes an excerpt from Wikipedia.
Then it looks for that kgmid in Wikidata, in P2671 (Google Knowledge Graph ID) and P646 (Freebase ID). If Google gives a Wikipedia article, the tool also checks which Wikidata item that article belongs to and which Google identifier that item has.
Finally it compares both leads, which gives one of three statuses. What the Knowledge Graph is and where Google gets its data, I explain in my post on the Knowledge Graph and Knowledge Panel.
Result
Three statuses and what they mean
Confirmed by identifier
A Wikidata item has the same kgmid. Google and Wikidata describe the same entity.
Mine:
/g/11md2bpb8_= Q133444548Mismatch
The Wikipedia article given by Google belongs to an item with a different kgmid. These are two different entities.
“Kraków Główny”: bus stop
/g/11x_97jms7, station/m/02rn23xNot linked
No Wikidata item has this kgmid. That is common for smaller brands.
If it is your entity, add the kgmid to its item.
Similar names from Wikidata appear only on request, in a separate box marked “to check”. The tool never links entities by name, because with common names that easily attaches someone else’s item.
Important
An empty result does not mean Google does not know you
The API returns only part of the Knowledge Graph. A knowledge panel can show up in search even if the API does not return it, and an entity in the API does not guarantee a panel. Google itself says the API is not suitable for production-critical use.
So with an empty result the tool says it carefully: Google did not return this entity in the API. A check by identifier is more precise than by name. You can find the kgmid in a knowledge panel: click “Share”, open the copied g.co/kgs/… link and look for the kgmid= parameter in the address bar. Paste the whole address into the tool.
Privacy
What happens to the name you type
The podrez.pl server sends the name or kgmid to Google, so Google does not see your IP address. The server keeps Google’s answer for 24 hours under a hash of the query, without your IP. I keep no list of the names people type.
Requests to Wikidata and Wikipedia go straight from your browser. Wikimedia sees your IP address and the identifiers: kgmid, QID and article title. It gets the name you typed only if you click “Show similar names in Wikidata”.
A link to a result keeps the name after the # sign, the part of the address that browsers do not send to the server. When you open such a link, the tool removes it from the address bar.
What I measure. Google Analytics only learns that someone used the tool, the type of result (e.g. “confirmed” or “not linked”) and which button was clicked, e.g. “Open the knowledge panel in Google”. No name, no identifier, and only in line with your cookie settings.
Before you fix anything
What to do with the result
- Confirmed: check whether Google’s short description fits who you are. It is Google’s own text. You can only influence it indirectly, with consistent descriptions in the sources Google uses.
- Mismatch: work out which entity is yours. Fix
sameAson your site and the identifier in the Wikidata item, but do not force someone else’s kgmid onto your record. - Not linked: if it is definitely your entity, add the kgmid to its Wikidata item:
/g/…as P2671,/m/…as P646. How to edit an item, I show in my Wikidata step-by-step guide. - Empty result: start with the entity on your own site (schema with
sameAs) and a Wikidata item.

What next
Google doesn’t know you, or knows you wrong?
A mismatched entity, no Wikidata item, a description that doesn’t fit you, or two entities with the same name. This is the kind of thing I sort out in entity SEO work.

Frequently asked questions
How do I check if I am in Google’s Knowledge Graph?
What is a kgmid?
/m/… (older entities, from the Freebase era) or /g/… (newer ones). You can see it in a Google search address, in the kgmid parameter, e.g. after opening the “Share” link of a knowledge panel.Does an empty result mean I have no knowledge panel?
How do I find my knowledge panel?
What does the score mean?
resultScore, a measure of how well an entity matches the query. It is comparable only within a single search, so the tool shows it as a percentage of the top result.Why doesn’t the tool match Wikidata by name?
Where does a mismatch come from?
/g/… entity instead of using an existing one, e.g. for a bus stop with the same name as a railway station, and takes the description from an article about something else. A mismatch can also come from a wrong identifier in the Wikidata item.How often can I check?
Do you store the names I check?
