Full review
Ahrefs is an SEO toolset built around one of the largest backlink databases available, used for keyword research, competitor analysis, site audits, and rank tracking — with AI features added more recently for content briefs and AI-assisted analysis of SEO data.
Its backlink index and keyword database are frequently cited as best-in-class for accuracy and size, making Ahrefs a preferred choice for link-building research and competitive analysis specifically; AI features help interpret this data faster (summarizing a site's SEO strengths and weaknesses, suggesting content opportunities based on keyword gaps).
Pricing starts around $129/month, comparable to Semrush, and the two are frequently compared directly — Ahrefs is often considered to have an edge in backlink data, while Semrush offers broader marketing tool coverage beyond pure SEO. For SEO-focused teams prioritizing backlink and keyword research depth, Ahrefs is a leading choice; for broader marketing tool needs, Semrush's wider scope may be more efficient.
