The data is an estimate, not a measurement
Search volume, traffic and ranking figures in both tools are estimates based on their own models; on niche queries and in smaller languages such as Turkish, the gap can grow. The real data for your own site comes from Google Search Console and your analytics.
Who should pick which?
For small marketing teams that want SEO, advertising and content research in one tool, Semrush is practical. SEO specialists who do in-depth link profile analysis and organic competitor research may prefer Ahrefs.

Do we need both?
For most teams one is enough. Agencies and large SEO teams sometimes use both for their different strengths.
Can I measure AI visibility with these tools?
