Good SEO tools can get expensive fast. Keyword research, site audits, content optimization, and technical checks can easily turn into several subscriptions, even when you only need each one for part of the job.
AI has opened up more useful free options for everyday SEO work. You can now research keywords, review pages, find content issues, run audits, and check search visibility without paying for another full SEO platform. The tools below are a good place to start.
