Our Recommendation

If you're an SEO specialist who lives in backlink analysis and keyword research, Ahrefs is the sharper tool. If you're a marketing manager who needs SEO + content + PPC + social in one dashboard, Semrush gives you more bang for the buck.

For European markets specifically, Semrush has significantly better keyword databases for smaller languages (Swedish, Norwegian, Danish, Finnish). Ahrefs is catching up but still lags in Nordic keyword coverage.
