What percentage of Google Knowledge Panels are sourced from Wikipedia?

The exact percentage of Knowledge Panel content sourced from Wikipedia is not published by Google and varies by entity type, but the relationship is strong enough that Wikipedia work is the most reliable lever for improving a Knowledge Panel in practice. For most entities with an active Wikipedia article, the Knowledge Panel’s short description, key facts, and structured fields trace back to the article and to its linked Wikidata entry. For entities without a Wikipedia article, the panel often lacks the descriptive layer entirely, with only structured-data fields like founding date and headquarters appearing if the entity has them in other authoritative sources. The combined Wikipedia plus Wikidata layer is one of the strongest signals in Google’s Knowledge Graph, which is the broader dataset Knowledge Panels are built from. The practical implication for reputation work is that improving Wikipedia and Wikidata content is the most consistent way to improve Knowledge Panel quality, more so than direct Google submissions through the panel feedback interface.
