Your robots.txt probably isn't blocking AI citations. Your CDN might be.

Founder of AuthorityTech and creator of Machine Relations, the parent category for GEO, AEO, AI SEO, LLM Optimization, and AI PR. Machine Relations (MR) is the discipline I coined in 2024 to describe how brands become legible, retrievable, and citable inside AI-driven discovery systems. As search shifts from human-mediated discovery to machine-mediated answers, most of the market describes fragments of the same change using labels like GEO, AEO, AI SEO, LLMO, and AI PR. My position is that these are not separate categories. They are tactics or layers inside the broader system of Machine Relations (MR).

The training vs retrieval split is useful, and the CDN layer is the one people skip. I’ve seen the same pattern: robots.txt looks open, but the edge is quietly blocking OAI-SearchBot or PerplexityBot, so the allow never matters. Auditing both layers, then checking Security Events for actual fetch attempts, is the right order before anyone worries about schema or “AI-ready” content.
