From Information Science to Algorithmic Engineering.

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.
