Traditional SEO optimises for crawlers that rank pages in a list. GEO optimises for AI engines that synthesise answers and cite sources directly. The signals that drive AI citations — answer capsules after H2 headings, FAQPage schema, attributed statistics, hierarchical headings — are structural, not keyword-based. Our scoring model is grounded in academic research: Aggarwal et al. (2024, Princeton / Georgia Tech) and the GEO Alliance signal studies. We update weights as new research emerges. ## Contact - Website: https://geofundamentals.com - Email: hello@geofundamentals.com - For audit enquiries: https://geofundamentals.com/contact
