Ahrefs is a private software company that develops a cloud-based suite of tools for search engine optimization. It provides data and analysis designed to help users improve organic search performance, content strategy, and link-building efforts. The platform centers on a large proprietary web crawler that indexes the web to gather information about websites, pages, and their backlink profiles.

The Ahrefs toolset includes several core products. Site Explorer analyzes any domain or URL to reveal backlink profiles, referring domains, anchor text distribution, and estimated organic search traffic. Keywords Explorer offers metrics for researching search terms, such as search volume, difficulty, clicks, and potential traffic. Content Explorer helps users discover popular content by examining backlinks, social shares, and overall reach. Rank Tracker monitors keyword rankings across locations and devices, while Site Audit crawls a site to identify technical SEO issues. Alerts notify users of changes in backlinks or keyword rankings.

Data and methodology are centered on the company’s own crawling and indexing processes. The platform emphasizes up-to-date backlink data, keyword metrics, and site health insights derived from its crawls and analysis, with reporting designed for actionable SEO workflows.

Audience and usage are primarily professional services, including SEO specialists, digital marketers, and agencies. Common applications include competitive analysis, keyword and content discovery, link-building planning, and ongoing performance monitoring across projects and clients.

Business model and history are consistent with a SaaS provider offering subscription plans of varying scope and capacity. Since its inception in the early 2010s, Ahrefs has expanded its product lineup and built a global user base through its data-driven approach to SEO.
