What is Ahrefs and what is it used for?
Ahrefs is an SEO platform that combines keyword research, backlink analysis, technical site audits and Google rank tracking in one subscription.
SEO, content and marketing teams use it to decide which topics to publish, to understand why a competitor ranks above them, and to find technical problems that keep pages from being indexed.
The core set has six tools: Site Explorer, Keywords Explorer, Site Audit, Rank Tracker, Content Explorer and Brand Radar. Brand Radar tracks brand mentions in AI tools such as ChatGPT, Gemini, Perplexity and Copilot.
There is also Ahrefs Free, formerly Ahrefs Webmaster Tools, with Web Analytics, Site Audit and Site Explorer for sites whose ownership the user verifies. From the Lite plan up, API and MCP access come with the subscription. The descriptions come from the vendor itself.
