Detailed SEO Extension is a browser-based SEO analysis tool developed by industry practitioner Glen Allsopp. It is designed to provide quick on-page SEO insights directly within Google Chrome. The extension is widely used by SEO consultants, affiliate marketers, and digital strategists conducting competitor analysis and technical reviews.
Rather than functioning as a full SaaS platform, Detailed SEO Extension operates as a lightweight inspection tool. It allows users to analyse headings, meta data, canonical tags, schema markup, and indexing signals on any webpage instantly. This makes it particularly useful during manual audits or SERP research sessions.
For professionals who need fast and accurate on-page diagnostics without leaving the browser, Detailed SEO Extension offers practical and efficient functionality.
