# Knowledge Graph

The Knowledge Graph is Google’s database of entities and the relationships between them: people, companies, places, works and the facts connecting them. The Knowledge Graph is what lets a search system answer about a subject rather than return documents mentioning a phrase, and it is not directly editable by site owners.

## What goes into the Knowledge Graph?

Facts extracted and corroborated across many sources, weighted toward the ones the system already trusts. Structured data on your own site is an input rather than a shortcut: it tells Google what you claim, and corroboration elsewhere is what turns a claim into a stored fact. That asymmetry is the reason a small company can be perfectly marked up and still absent.

## Can you get yourself into it?

Not directly, and there is no application form. What you can do is make the corroboration easy: one canonical name, consistent descriptions across the profiles you control, `sameAs` links between them, and a factual page about the company that other people can cite. Everything after that depends on other people writing about you.

The honest admission most guides skip: nobody outside Google can see what the Knowledge Graph holds about a private company, and the Knowledge Graph Search API was deprecated, so there is no supported way to query it. You are optimising against something you cannot inspect. What you can inspect is the proxy: search your brand name and read what Google returns about the entity rather than the pages.

If the results describe a different company with a similar name, the problem is resolution rather than ranking, and more content will not fix it. The fix for a collision is corroboration, not volume: get the distinguishing facts stated consistently in the places that already describe you, and let the difference between the two entities become visible in the sources rather than only on your own site.

## Does the Knowledge Graph matter for AI answers?

For Google’s surfaces, plainly yes, since [AI Overviews](/glossary/ai-overview) and AI Mode are built on the same stack. For the assistants it is less direct: each keeps its own index and none documents using Google’s graph. What travels across all of them is the underlying condition rather than the database, which is being a well-described entity in many places.

That is the practical reframing. Chasing a Knowledge Panel is chasing one visible output of a process; the process itself is what every engine responds to, and it is worth doing whether or not the panel ever appears. The work itself is unglamorous and finite: settle the name, publish a factual page about the company, make the profiles you control agree with it and with each other, and connect them with `sameAs`. That is an afternoon, and it is most of what anybody outside a large brand can actually do about entity resolution.
