Semrush vs Ahrefs
The defining rivalry in SEO software: the broad marketing suite against the data specialist. In 2026 the AI-visibility race added a new dimension.
Semrush
The everything-suite, now tracking AI answers too.
Ahrefs
The backlink king with the cleanest data in SEO.
Our verdict
Semrush wins for breadth and for the AI era: PPC, content, and social tools next to SEO, plus Semrush One’s tracking of brand visibility in ChatGPT, Perplexity, and Gemini included rather than sold separately (Ahrefs charges $199 a month extra for Brand Radar). Ahrefs wins on the data itself: the industry’s largest live link index (around 500 million referring domains) and the interface professionals find faster for pure SEO work. Agencies and marketing teams: Semrush. Link builders and SEO specialists: Ahrefs. Both punish casual users with professional pricing; check SE Ranking first if you are not sure you need either.
“The most complete marketing suite in the business, and with Semrush One it moved first on the AI era: tracking how often ChatGPT, Perplexity, and Gemini mention your brand. Expensive, occasionally overwhelming, and still the safest professional default.”Editorial team, on Semrush
“The tool SEO professionals trust most for the data itself: the largest live backlink index in the industry and a keyword explorer that rarely misleads. Less broad than Semrush, more loved by specialists, and the Brand Radar add-on answers the AI question for $199 a month extra.”Editorial team, on Ahrefs
