Ahrefs has officially acquired Detailed.com and the Detailed SEO Extension, bringing a widely used on-page auditing tool and its research-driven content brand under the Ahrefs umbrella. As part of the deal, Detailed founder Glen Allsopp is joining Ahrefs full-time to work on marketing strategy, research, and product development.
What Was Acquired?
The acquisition includes the Detailed website, its browser extension, and several smaller domains and extensions. Detailed.com, launched in 2020, is renowned for its long-form, data-driven SEO research and practitioner tips. Over the past 12 months, the site recorded 970,000 unique visitors. The Detailed SEO Extension boasts over 450,000 weekly users on Chrome and approximately 7,000 on Firefox.
Key Features of the Detailed SEO Extension
The extension is designed to speed up page-level checks that SEO professionals perform during audits and competitive reviews. It surfaces critical data in a single panel, including:
- Title and meta tags
- Heading structure
- Robots directives
- Schema markup
It also offers advanced options for highlighting nofollow links, inspecting hreflang, viewing status codes, extracting People Also Ask results, switching the user agent to Googlebot, and jumping the current URL into popular research tools for deeper analysis.
What Changes for Users?
Glen Allsopp confirmed that the extension and all its current functionality will remain free for all users. If premium capabilities are added in the future, they will be additions rather than moving existing features behind a paywall. There are no current plans to introduce paid tiers.
On branding, the extension will keep the Detailed SEO Extension name but will operate as "Detailed, an Ahrefs brand." Users don't need to take any action, and updates will continue as normal through existing Chrome and Firefox listings.
Looking Forward
This move adds a high-usage browser utility and a respected content brand to Ahrefs' portfolio. If Ahrefs integrates or expands the extension's capabilities over time, SEO practitioners could see faster iteration on features that support day-to-day site audits, on-page reviews, and competitive analysis.
