The 10 highest-leverage Wikidata properties for AEO: (1) P31 (instance of) — declare what kind of thing you are ("business," "software," "nonprofit organization"). (2) P17 (country) and P159 (headquarters location) — geographic disambiguation. (3) P571 (inception) — founding date; engines use this for "how old is [brand]" queries. (4) P112 (founded by) — founder linkage; itself a separate Wikidata item ideally. (5) P856 (official website) — canonical URL, which engines use to verify the brand-to-domain mapping. (6) P2002 (Twitter/X username), P2013 (Facebook ID), P4264 (LinkedIn company ID), P2003 (Instagram username), P2397 (YouTube channel ID) — social-graph linkage.

Tactically: create the Wikidata item before you create the Wikipedia article (Wikidata is more permissive and feeds Wikipedia anyway), back every claim with an external reference, and link the item from your site's Organization schema using sameAs: "https://www.wikidata.org/wiki/Q[your-id]". Most AEO gains from Wikidata land within 30–60 days as engines re-index.
