What this tool shows you
- Every match, not just the first
- Up to 500 entities per search, with Google's score, types, description, Entity Home and source.
- Name or id, one box
- Search by name, or paste one or many KGMIDs, a Google search URL with kgmid=, a share.google link, a Search profile link or an @handle.
- An entity grade you can check
- An A–E grade from three published parts: match score, completeness and clarity. No black box.
- Namesake detection
- Spots other entities with the same name and type, and how far ahead your entity is.
- Fixes, in order
- A six-point checklist and specific next steps for whichever entity you audit.
- Wikidata cross-check
- Finds the Wikidata item and Wikipedia article for each id, and flags a website mismatch.
- Filters Google supports
- Language, schema.org type, result count and prefix matching.
- Schema and exports
- JSON-LD for your Entity Home, CSV and JSON exports, and a shareable link to every search.
How to read the results
The data comes from Google's official Knowledge Graph Search API, the same source other entity tools use. Each result is an entity with an id, a name, one or more schema.org types and, when Google has them, a subtitle, a detailed description with its source and an Entity Home url.
The score is Google's resultScore. It measures how well an entity matches your query, and it rises with how well known and well sourced the entity is. Compare scores within one search: Google's own entity scores in the tens of thousands, while most people and small businesses score well under a hundred.
Ids starting with /m/ came from Freebase, which Google closed in 2015. Ids starting with /g/ were created by Google since. Every result links to Google with ?kgmid=, so you can see which knowledge panel or search result each id opens.
How the entity grade works
The grade rates the entity you're auditing, which is the best name match by default. It combines three parts, and the tool shows each one:
- Match score (50%). Google's resultScore on a log scale, where 5,000 or more counts as full marks.
- Completeness (30%). How many of the six checks below the entity passes.
- Clarity (20%). Whether namesakes of the same type exist, and how far ahead of the strongest one the entity is.
| Specific type | Typed as Person, Organization or similar, not only Thing. |
|---|---|
| Subtitle | Google has a one-line description, like “Entrepreneur”. |
| Detailed description | A source-backed paragraph, usually from Wikipedia. |
| Entity Home | Google links the entity to a website. |
| Wikidata item | A Wikidata item carries the id. |
| Wikipedia article | Shown for context; not counted against you in the fixes. |
The grade is a heuristic of mine, not a number Google publishes. Use it to spot gaps and track progress, not as a ranking factor.
Why your Knowledge Graph entity matters
When Google holds your brand as a clear entity, it can show a knowledge panel, answer questions about you with facts instead of guesses, and connect your website, profiles and mentions to one thing. AI assistants that ground their answers in Google's index and Knowledge Graph benefit from the same clarity. A weak or duplicated entity is how brands end up described wrongly, or confused with someone else who shares their name.

Frequently asked questions
What is the Google Knowledge Graph?
It's Google's database of things (people, companies, places, books, films and ideas) and the facts that connect them. Knowledge panels, many AI Overview answers and Gemini's grounding all draw on it. If Google holds your brand as an entity, it can state facts about you instead of guessing from web pages.
What does the score mean?
It's the resultScore Google's Knowledge Graph Search API returns for each entity: how strongly the entity matches your query, which tracks how well known and well sourced it is. It is relative to the query, so compare scores within one search. A big brand scores in the thousands; a small business or person often scores under 100.
What is a KGMID and how do I find mine?
A KGMID is an entity's Knowledge Graph id, like /g/11cn2_bbrr or /m/045c7b. Search your name here and copy the id from your match. You can also share your knowledge panel from Google and paste the share.google link into this tool; it reads the id behind it.
What's the difference between /m/ and /g/ ids?
Ids starting with /m/ came from Freebase, the open database Google bought in 2010 and closed in 2015. Ids starting with /g/ were created by Google afterwards. Neither is better, but a /m/ id tells you the entity has been known for a long time.
Why are there several entities with my name?
Google often creates more than one entity for the same person or brand, for example one from Wikipedia and one from a book or social profile. The tool flags namesakes that share a type. If more than one is you, point every profile at a single Entity Home and keep your name and description identical everywhere, so Google can merge them.
What is an Entity Home?
The page Google treats as the authoritative source about an entity, usually the official website or its About page. The Knowledge Graph API returns it as the entity's url. If yours is missing, Google hasn't connected your entity to your website yet.
My name returns no entity. What now?
Google hasn't recognised you as a thing yet. Build one clear Entity Home with Person or Organization schema, use the same name and one-line description on every profile, and earn mentions on sites Google already trusts. Then check back here: new entities usually appear with a /g/ id and a low score first.
How it works: searches go through a small server endpoint that calls Google's Knowledge Graph Search API and Wikidata's query service. It stores nothing and caches results for a few hours. Your recent searches stay in your browser.
