Free SEO Audit Tool
Analyze any page's on-page SEO in seconds.
What is the SEO Audit Tool?
Search engines judge a page on dozens of on-page signals — is the title the right length, is there a single clear H1, do images have alt text, is the page even allowed to be indexed? Missing any of them quietly holds back rankings, and they're easy to overlook by eye.
This SEO audit tool fetches any page and checks those fundamentals for you, returning a score and a plain list of what passes, what needs attention, and what's broken.

What does this tool do?
You enter a URL and the tool retrieves the page and inspects its HTML — the title and meta description, canonical link, heading structure, mobile viewport, language attribute, robots directives, image alt text, Open Graph tags, HTTPS and content length.
It grades each check as pass, warning or fail, adds up an overall score, and shows supporting details like word count and internal-versus-external link counts, so you know exactly where to focus.

Tips
- Keep titles roughly 30–60 characters and descriptions 120–160.
- Aim for exactly one H1 per page.
- Give every meaningful image descriptive alt text.
- Make sure the page isn't accidentally set to noindex.
- Add a canonical link to avoid duplicate-content issues.
- Run the audit on each important page, not just the homepage.
- Fix fails first, then warnings, for the biggest gains.
- Re-audit after changes to confirm they took effect.
Common mistakes to avoid
Auditing only the homepage
Fix: Run it on every important page — issues vary page to page.
Ignoring a noindex warning
Fix: A page set to noindex won't rank at all; remove it unless intended.
Titles too long or too short
Fix: Aim for about 30–60 characters so they read well and don't truncate.
Treating warnings as pass
Fix: Warnings are near-misses worth fixing, not just fails.
