An SEO audit evaluates the search engine optimization friendliness of a website at a point in time. It identifies factors slowing traffic growth and assesses problem severity. The audit examines technical, semantic, link popularity, and competitive elements. Technically, it checks the server, crawlability, page speed and templates. Semantically, it evaluates keywords, coverage, targeting and content quality. For links, it considers volume, quality and abnormal patterns. Competitor audits mirror these analyses. Regular audits are important as things change without notice. The website owners and editors are also important to audit.
