The good SEO audit tools are locked behind expensive subscriptions.
The free ones barely scratch the surface.

Where it started

Four-plus years of running technical audits and local SEO campaigns will teach you exactly where the tools you're paying for — or not paying for — fall short. I kept hitting the same wall: real audit depth costs real money, and most of the free options are built to get you to upgrade, not to actually help you find what's wrong.

Great SEO Tool is what I built instead of just complaining about it — a full technical audit platform for freelancers, in-house marketers, and agencies who want the real thing, not a taste of it.

What makes it different

This isn't a stripped-down demo of a paid product, and it isn't a vanity score either. It crawls your whole site, checks what actually matters, and hands you findings you can act on. Every single check in here exists because it solved a real problem I ran into doing SEO work — not because it looked good on a features list.

Why free

Good technical SEO insight shouldn't sit behind enterprise pricing. Great SEO Tool stays free so more people can actually fix what's broken on their site — not just get a locked report telling them that something is.

What's next

This isn't a finished product I've walked away from — it's one I'm still in. Adding checks, fixing what breaks, shaping it around real feedback from real audits, not a roadmap I wrote once and forgot about. If something doesn't work right, or you think of something that should be in here, tell me. I'll actually read it.
