For pure SEO work, both tools are capable. However, SEMrush offers PPC, social media, and content marketing tools that Ahrefs does not. If you only need SEO, either works well. If you need broader marketing tools, SEMrush offers more.
SEMrush is generally preferred by agencies because it offers client management features, white-label reporting, and a broader toolkit covering SEO, PPC, and social media. Ahrefs is often the specialist tool agencies add for deeper backlink analysis.
Both tools use different algorithms for keyword difficulty. Ahrefs focuses on backlink requirements to rank, while SEMrush considers multiple factors. Many SEO professionals recommend checking both tools for a well-rounded view of ranking difficulty.
