Siri Optimization: Apple Maps, Yelp, and Knowledge Graph for iOS Voice AEO
Siri - Apple's voice assistant with approximately 31% voice assistant market share across iPhone, iPad, Mac, Apple Watch, and Apple TV - operates from a fundamentally different data stack than Google Assistant. Where Google Assistant relies on Google Business Profile and Google's Knowledge Graph, Siri sources local business data primarily from Apple Maps and Yelp. This creates a systematic blind spot for businesses that optimize exclusively for Google: strong GBP optimization contributes zero to Siri local voice visibility.
Apple Maps Connect - the business management portal for Apple Maps listings - requires active claim and verification by business owners. Unlike GBP, Apple Maps does not auto-populate business listings as completely or accurately from web crawling. The result: many businesses with excellent GBP optimization have unclaimed or incomplete Apple Maps listings, generating zero Siri local visibility for the third of voice queries that Siri handles.

Siri Query Types - Answer Sources and Optimization Strategy
Four Siri query types showing where each answer comes from and the specific AEO action required:
“Hey Siri, what is the capital of Spain?”
Apple Knowledge Graph + Wikipedia
AEO strategy for this query type
Factual lookups source from Apple's knowledge graph (populated from structured data on entity pages) and Wikipedia. For AEO: ensure your entity's Wikipedia article is accurate, publish Organization schema with sameAs linking to your Wikipedia entry, and ensure your entity has clear structured data associations for the facts you want attributed.
