Most free audit tools check twelve things and sell you the rest. This one runs more than 60 checks across nine categories, shows the exact value it found for every check, and tells you what to do about it.
It covers indexability (status codes, redirect chains, canonical, robots meta and header, robots.txt, sitemap inclusion, soft 404s), on-page fundamentals, content quality and readability, structured data validity, internal and broken links, image alt and format, Core Web Vitals from both lab and real-user data, security headers, and AI answer-engine readiness including whether GPTBot, PerplexityBot and Google-Extended can reach you.
Where this tool actually helps
Before publishing a new page
Catch missing title tags, thin content and broken canonicals before Google does.
Diagnosing a page that ranks but does not convert
Poor mobile CWV and heavy JS payloads often explain the drop-off between impression and click.
Sanity-check a competitor
See how their on-page and CWV compare to yours. It is usually the boring stuff.
How to read the result
Every check carries a weight of 1 to 3 based on how much it actually moves rankings. A pass earns full weight, a warning earns half, a failure earns nothing. The category scores and the overall score are both weighted percentages, so a failed viewport tag hurts far more than a missing twitter:card.
Start with the "Fix these first" list. It is ordered by impact across every category, not grouped by type, so you are always working on the highest-value item next.
The Core Web Vitals block shows lab data from Lighthouse and, when Google has enough traffic on your URL, real-user (field) data. Field data is what actually feeds into ranking.
Common mistakes we see
- Chasing a 100 Lighthouse score. 90+ on mobile is enough. Real users are what matter.
- Fixing every warning. Two or three high-severity issues usually explain 80 percent of the loss.
- Auditing only the homepage. Money pages (services, product, pricing) deserve their own audits.
- Ignoring the internal link count. A page with two internal links pointing to it will not rank, no matter how good the content is.
FAQs
- Does this store my URL?
- No. We fetch the page once to run the checks and throw the response away.
- Why do mobile and desktop scores differ so much?
- Google measures mobile with a throttled 4G network and slower CPU. Mobile is usually 20–40 points lower and it is the one that counts.
- Can I audit password-protected pages?
- No. This works on publicly reachable URLs only. Ask us for a manual audit if you need it.
- Why is field data missing sometimes?
- Google only shows real-user metrics when a page has enough Chrome traffic. New or low-traffic pages will show lab data only.
A note from Nimitt
A tool gives you a number. A person tells you what to do with it. If you want a straight answer on your site, send it over. I read every one myself.
