Feature-by-feature comparison
Verdict
Pick Semrush Business if your agency is small enough that $500/mo flat is fine and you want one dashboard. Pick Ahrefs Standard if backlink depth and content explorer carry the weight. For 300 clients with surprise-overage anxiety, neither is the right primary — DataForSEO PAYG for SERP + one of these for depth queries beats both.
Consider Scavio instead
Scavio fills the AEO/AI Overview tracking gap that both Semrush and Ahrefs cover only partially. Pair Scavio with DataForSEO (PAYG SERP) and keep one of these for depth — total agency stack stays under $600/mo for 300 clients.
