About the Free Technical SEO Audit Tool
Run a free technical SEO audit on any URL. Check indexability, canonical tags, robots rules, sitemap coverage, structured data, security headers and page speed, then get a scored fix list.
This free technical SEO audit fetches your page the way search engines do and reports the crawl and index signals that quietly hold rankings back: indexability directives, canonical handling, robots rules, sitemap coverage, structured data, HTTPS and security headers, page weight and load time.
Technical signals the audit checks
- Indexability - noindex directives, X-Robots-Tag headers and conflicting robots signals.
- Canonical tags - self-referencing canonicals, canonical chains and canonical or redirect conflicts.
- Robots.txt - rules that block key pages, or the CSS and JS assets search engines need to render.
- XML sitemap - missing, redirected or non-canonical URLs inside the sitemap.
- Structured data - JSON-LD and Microdata types, validity and missing rich-result fields.
- HTTPS and headers - certificate status, HSTS, mixed content and security headers.
- Performance - load time, page size, compression, caching headers and render-blocking assets.
- Mobile and rendering - viewport configuration and content that only exists after JavaScript runs.
When to run a technical SEO audit
Run one after every site migration or redeploy, before publishing a new section, the day organic traffic drops without a content change, and monthly on any site that earns revenue from search. Technical regressions are invisible in dashboards until rankings already moved.
Technical SEO audit vs. on-page SEO check
Technical checks look at how crawlers reach and interpret your pages. On-page checks look at what is inside a page: title, meta description, headings, keyword coverage, images and internal links. Audit the technical layer first, because a perfectly optimised page that cannot be indexed will never rank.
Frequently asked questions
What is a technical SEO audit?
A technical SEO audit reviews the infrastructure that lets search engines crawl, render and index your pages, including robots rules, sitemaps, canonicals, structured data, HTTPS and page speed.
Is this technical SEO audit free?
Yes. The audit, the scored report and the CSV export are free, with no credit card and no signup required to run your first check.
How often should I run a technical SEO audit?
Monthly for sites that depend on organic traffic, and immediately after migrations, redesigns, platform changes or major template edits.
Does the audit check Core Web Vitals?
It measures load time, page weight, compression and caching headers, and flags render-blocking assets. For field-level Core Web Vitals data, pair it with the PageSpeed checker.
Can I audit any URL?
Any publicly reachable HTTP or HTTPS page works. Localhost, private network addresses and password-protected pages cannot be audited.
What does the report include?
An overall SEO score, every passing and failing check with its importance, the detail behind each finding and a recommended fix per issue that you can export as CSV.
