Best AI tools for SEO

Research suites first, on-page editors second.

SEO tools that added a writing model are still data products. We rank the data first.

  1. 1

    Ahrefs

    The research index we would buy first.

  2. 2

    Semrush

    The broader suite if more marketers need the login.

  3. 3

    Surfer

    The on-page editor. Also a paid placement in the SEO category, disclosed there.

    Editorial position. This vendor also has a paid placement, shown separately when it targets this page.

Bottom line

Ahrefs, then Semrush, then Surfer for the draft. Buying only Surfer leaves you without a research suite.
