EXECUTIVE SUMMARY
-
Signal 1: Entity Strength.
Wikipedia article. Google Knowledge Panel. Consistent structured data. The foundation — without it, the other three signals cannot do their job. AI engines build an internal model of a brand from these entity signals before evaluating whether to cite it.
-
Signal 2: Consensus Corroboration.
Mentions across independent trade, review, and news sites. LLMs apply rough multi-source corroboration; a brand consistently referenced across independent domains is treated as more reliable than one mentioned in a narrow set. This is structurally a PR deliverable.
-
Signal 3: Content Architecture.
Q&A, listicle, or comparison structure. First 150 words answer the query directly. Named, dated sources. Schema markup (FAQPage, HowTo, Product, Review, Article). AI engines preferentially extract content formatted as reference material.
-
Signal 4: Freshness and Depth.
70% of AI Overview citations rotate out over 2–3 months. GEO is an ongoing program, not a one-shot optimization. The correct analogy is less "build a website" and more "maintain a press office." Quarterly content refreshes are the minimum sustainable cadence.
