Our verdict

For pure SEO and backlinks, Ahrefs is the sharper tool. For a team that does SEO plus paid search and content, Semrush covers more ground. Both offer ways to try before you commit, so test them on your own site.

Features and pricing change often. Check both vendors' websites for current plans before you buy.
