# SEOntology

> SEOntology (namespace https://w3id.org/seovoc/, prefix seovoc:) is a Schema.org-aligned OWL 2 ontology for modeling SEO workflows — pages, queries, links, content chunks, search and analytics metrics, quality scores and structured-data profiles — as provenance-aware knowledge graphs.

Current version: 0.1.0. Every page below is also available as Markdown; the links point to those Markdown files.
