Knowledge Base
A knowledge base is a collection of information about a particular subject. Software companies use the term for a help center of how-to articles for customers or staff. In SEO and AI search, it means a store of facts about people, places, businesses and things that software can look up, like Wikidata or Google's Knowledge Graph.

What Knowledge Base means for your business
Most searches for this phrase are about help-center software. If you run a help center, it's part of your website like any other page, and clear answers there help the buyers who read them. This entry is about the other kind.
Of these fact stores, Wikidata is the one anyone can see and edit. It calls itself a free, collaborative knowledge base that collects structured data for Wikipedia and for anyone in the world. You'll hear knowledge base and knowledge graph used for the same thing. Either way, a business owner wants to know two things: is there a record about you, and is it right?
Not every business belongs on Wikidata, since for an item without a Wikipedia page its rules ask that the thing be clearly identifiable and described in serious, public sources. If a public database lists an old name, a closed location or the wrong website for your business, getting that record put right falls under our entity work.
