Technical SEO Audit Tool
Content cannot outrank a broken technical foundation.
Technical SEO is everything that must be right before content gets a chance: crawlability, indexability, status codes, canonical signals, security, and site structure. CheckSEO runs 30+ technical checks against the rendered site — the same surface Google evaluates — and returns a prioritized fix list.

Frequently Asked Questions
What does a technical SEO audit actually check?
Whether search engines can crawl, index, and trust your site: robots rules, sitemaps, canonical and noindex signals, status codes, redirects, SSL, titles and meta tags, headings, and internal link health.
How often should I run a technical audit?
After every significant deploy, and on a monthly schedule otherwise. Most technical regressions are introduced by routine site changes, not by Google.
