Ahrefs
Research search demand, links, and site health.
What is Ahrefs?
Ahrefs provides tools for exploring websites, keywords, backlinks, technical issues, and search visibility. Its platform can support both research into competing sites and improvements to properties you control, with different access levels across plans. Use the data to prioritize investigations rather than as a complete record of another business: third-party estimates and crawl observations have limits that require interpretation.
