Founded by librarian in training and information retrieval specialist Alexander Rodrigues Silva, Semântico SEO was born in Porto Alegre with the goal of challenging purely mechanical SEO based on keyword density.
We use century-old principles of bibliographic classification, faceted taxonomies, and structured ontologies applied directly to the semantic web, Google Knowledge Graph, and modern Graph-Augmented Retrieval (GraphRAG) systems.
Our mission.
The mission of Semântico SEO is to unite the fundamental knowledge of Library Science with excellence in SEO, structuring online content so that it is found, classified, and understood. We accomplish this through optimization projects created together with our clients, transforming their digital presence into a source of authoritative knowledge and high organic performance.
