Most SEO suites dangle a tiny free search count to get you to upgrade. A few free tools are genuinely useful on their own. I ranked these on how much real work you can do per day before the limit stops you.

How I ranked these

  • Daily free usage limit
  • Whether the core job (keywords, audit, rank tracking) works free
  • Data quality versus the paid version

Rankings are based on research, not paid placement. Some links are affiliate links, which never change where a tool ranks.
