What GEO / AEO practitioners can learn from David Lewallen
- **Become a clear entity first**: keep brand, product and people consistent across Wikidata, your site and third-party sources so AI can merge scattered mentions into one "you." - **Feed the graph with structured data**: Schema.org, sameAs and explicit relationships help engines place you in the right knowledge neighborhood. - **Fact density beats rhetoric**: verifiable facts, numbers and relationships are recited by AI far more readily than flourish.
