Most SEO problems on small sites are not about content strategy. They are plumbing: a robots.txt rule that blocks a section by accident, a canonical tag pointing at the wrong URL, a sitemap that lists redirects, a share image that never loads. These are quick to fix once you can see them, and invisible until you look.
Each tool here checks one of those things and tells you what it found in plain language. If you are not sure where to start, run the on-page SEO checker on your homepage for a broad pass, then use the focused tools to dig into whatever it flags.
Each checker report has its own shareable URL, so you can send the exact result to a teammate or a client, and a copy-ready prompt if you want an AI assistant to help with the fix.
