# SEO Deep Research

> An open research publication at https://seodeepresearch.com. Original, reproducible data studies on how search engines and AI assistants decide what to surface, cite, and recommend, including podcast and audio discoverability. Openly a project of The Discoverability Company (https://discoverability.co). Author: Drew Chapin.

Every study publishes a reproducible methodology, its raw dataset as CSV, charts rendered from that same data, a named author, a citation block, and a press-ready summary. Report codes follow the pattern SDR-YYYY-NN and are stable citation handles. Corrections are versioned and logged; datasets are never silently replaced.

Current status: the first study is in production. The site launches with it. The annual flagship report, State of AI Search, has its first edition (2026) in production.
