Read an experimental framework as research, not a guaranteed recipe for current products.
Evidence: Published experimental research, interpreted by GEO Primer. This note is not a replication, independent benchmark, or platform documentation.
Read Google’s AI guidance without inventing requirements
Distinguish documented eligibility from editorial recommendations and guaranteed inclusion.
Evidence: Platform documentation, interpreted by GEO Primer. This is not an independent experiment or an account of other providers’ requirements.
