GPT

GPT-5 Mini

Prefers Ahrefs0 vs 100

“Both are mature marketing platforms, but Ahrefs presents a clearer, more focused SEO + data-first offering with stronger technical and enterprise signals (crawler leadership, API, security certifications, academy and docs). Semrush offers a broader all-in-one marketing toolkit (SEO, PPC, social, local, PR) and may be a better fit if you want a single platform for multiple channel workflows, but Ahrefs edges it on data depth, integrations, and product maturity.”
