EntiScan

EntiScan is a free Chrome extension for SEO professionals, marketers, and web developers. It audits the page you are viewing and organizes technical and on-page SEO signals, headings, links, images, structured data, social metadata, entities, and semantic consistency. The initial analysis runs locally and does not require an account. It shows observable signals and context instead of reducing the audit to a single SEO score. You can export audits locally or optionally save reviewed snapshots to EntiScan Web after confirmation.
