A clear operating model for technical SEO, generative engine visibility, and the infrastructure that lets agents browse and act.
Three adjacent layers
Technical SEO helps search engines crawl, index, and rank pages. GEO improves how facts, claims, and sources are understood and cited in generated answers. Agent access tests whether autonomous software can reach, navigate, comprehend, and eventually act on the site.
The order matters
A site should first be technically healthy, then prove runtime agent access, then strengthen answer visibility. Tracking mentions before fixing a hard crawler block produces interesting charts but limited business value.
Use one evidence graph
The three disciplines can share canonical entities, page inventory, structured data, change history, and measurement. They should still retain separate scores and recommendations so teams know which problem they are solving.
