Ahrefs
SEO & Analytics
Research keywords, check backlinks and audit your site in one well-known toolkit.
Keyword, competitor and ad research with a bigger toolbox and a bigger bill.
Semrush does everything Ahrefs does and adds paid search research, social scheduling, content writing tools and local listings. If you want to see which Google Ads keywords a competitor is bidding on, this is the one.
Performance marketers tend to use it for the advertising research and keyword gap reports, then live in Ahrefs for links. It also has an official connection for Claude on its paid plans.
The sheer number of tools makes it cluttered, and every extra seat costs. Pick it if you need the ads research; otherwise Ahrefs is simpler.
Agencies and marketers who do both search ads and SEO and want one subscription for both.
