What is a GEO checker API?

A GEO (Generative Engine Optimization) checker API audits signals that help AI systems understand and cite a page — such as JSON-LD, FAQPage schema, /llms.txt, and robots rules for AI crawlers. It does not guarantee citations.

How is GEO different from SEO in Soni API?

SEO checks classic on-page signals. GEO focuses on generative-engine readiness. Use /api/v1/seo-checks and /api/v1/geo-checks respectively.
