Marin Popov is the founder of 1 Euro SEO and the creator of the 1 Euro SEO Intelligence Engine, the Business Diagnostic Atlas, and the Model Context Optimization (MCO) framework.

His work focuses on business diagnostics, evidence engineering, machine readability, semantic web architecture, and the intersection of artificial intelligence with search systems. Rather than treating AI as the product, he develops analytical frameworks that combine human strategic knowledge, engineered evidence, and frontier language models to produce business intelligence and deterministic machine-readable validation.

The Machine Readability Framework is his AI-era evolution of Technical SEO, designed to engineer websites so AI systems can reliably parse, interpret, retrieve, and connect their information.

Originally trained as a software engineer, he approaches SEO, business strategy, and AI from an engineering perspective, investigating how information is structured, interpreted, and validated by both search engines and AI systems. He is also the author of an Internet-Draft submitted to the Internet Engineering Task Force (IETF) proposing the Semantic Anchor—a protocol-level identity layer designed to enable deterministic discovery, verification, and connection of Organization, Person, and Service identities through a machine-readable authority graph.

His publications include Business Diagnostic Atlas: What Could Have Gone Wrong, Sweat, Tears & SEO Irony, and the SEO Contradictions series, reflecting his interest in documenting business reasoning, technical investigations, machine-readable systems, and the evolving relationship between search technology and artificial intelligence.
