SEO Site Auditor
Full SEO audit in one click — meta tags, redirects, Open Graph, Twitter Card, and security headers all analysed together.
Enter any URL for a comprehensive SEO audit — crawlability, on-page tags, page content quality, Open Graph, security headers, and Google Core Web Vitals checked in parallel with individual grades and actionable recommendations.
What is SEO Site Auditor?
SEO Site Auditor analyses any URL across five technical dimensions simultaneously — meta tags, redirect chain, Open Graph markup, Twitter Card tags, and HTTP security headers — and combines every finding into a single 0–100 score. Each check is colour-coded as a pass, warning, or issue and grouped by category, so you can see the full technical picture at a glance rather than piecing results together from separate tools.
Specifically, the audit covers: meta title and description (presence, length, and truncation risk), canonical tag and robots directive, redirect chain health and hop count, all Open Graph properties (og:title, og:description, og:image, og:type), Twitter Card tags, and key HTTP security headers including HSTS, X-Content-Type-Options, X-Frame-Options, and Content-Security-Policy. Use it to catch technical SEO issues before they affect rankings, verify a fresh deployment, or benchmark any publicly accessible competitor page. No login, no install, no limit on URLs.
Common Use Cases

FAQ
What does the SEO score mean?
The score (0–100) is calculated from the ratio of passed checks to total checks across all categories: meta tag presence and length, redirect chain health, Open Graph tag completeness, and security header coverage. A score above 80 means the page is well-optimised; 50–80 means there are improvements to make; below 50 means there are significant issues affecting crawlability, user experience, or social sharing.
How do I audit my website for SEO for free?
Enter your page URL into the auditor and click Audit — that is the entire process. The tool fetches your page server-side, runs all technical checks automatically, and returns a scored report within a few seconds. No account, no payment, and no limit on how many URLs you can check. For a thorough check, audit your homepage, your most important landing pages, and any pages you recently published or updated.
What is an SEO audit and why does my website need one?
An SEO audit is a structured review of the technical factors that influence how search engines crawl, index, and rank a page. Even well-designed websites commonly have silent issues — a missing canonical tag that splits ranking signals across duplicate URLs, a meta description that is too long and gets truncated in search results, or absent Open Graph tags that produce poor previews on social media. These problems compound over time: a redirect chain that adds three extra hops, combined with a missing security header, can slowly drain crawler budget and user trust. A regular audit catches issues before they affect traffic.
What does this SEO checker actually look for?
The audit checks five categories of technical SEO. Basic SEO: title tag (presence and character length), meta description (presence and length), canonical URL, and robots directive. Redirects: whether the URL redirects, the full chain of hops, and the final HTTP status code. Social sharing: Open Graph tags (og:title, og:description, og:image, og:type, og:url) and Twitter Card tags (twitter:card, twitter:title, twitter:description, twitter:image). Security headers: HSTS, X-Content-Type-Options, X-Frame-Options, Content-Security-Policy, and Referrer-Policy. Each finding is graded pass, warning, or issue with a clear explanation.
Is this SEO site audit tool completely free?
Yes. The SEO Site Auditor is free with no sign-up, no trial period, and no usage cap. Enter any publicly accessible URL and run the full audit as many times as you need. All checks are performed on our server — you do not need to install anything or add any code to your site.
How is this different from running each SEO tool individually?
The auditor runs all checks in parallel in a single request, returning results faster than using five separate tools one by one. It also combines every finding into a single prioritised report so you see the full picture at once — score, issues, warnings, and passes — without switching tabs or manually cross-referencing results.
Does this tool check Google rankings or backlinks?
No. This tool audits the on-page technical factors you control directly: meta tags, canonical tags, Open Graph data, HTTP headers, and redirect chains. Backlink analysis and keyword ranking data require access to third-party index data (such as Ahrefs, Moz, or Google Search Console) and are outside the scope of this tool.
How often should I run an SEO audit?
Run an audit whenever you publish a significant update, change your CMS, migrate domains, or update your server or security configuration. For active sites, a monthly check catches regressions before they affect rankings. For stable or low-traffic sites, a quarterly audit is sufficient.
