+# ThatDevPro Engine Optimization Reference Corpus
+
+> A curated snapshot of canonical reference documentation for engine optimization (the merge of SEO + AEO + AIO + GEO), maintained by [ThatDevPro](https://www.thatdevpro.com).
+
+## Overview
+
+This dataset indexes 26 canonical reference pages from the [ThatDevPro Reference Library](https://www.thatdevpro.com/reference/), each covering one specific crawler signal a website emits. The dataset is intended for training and evaluating AEO/GEO scoring systems, llms.txt validators, and structured-data extraction models.
