Free On-Page SEO Audit
Paste a URL and get the full on-page picture: meta tags, heading outline, missing alt text, internal linking and content depth — graded, with the fix spelled out for each finding.
Checks the tags, the heading outline, image alt text, internal linking and content depth — everything a crawler reads on one page.
Why use the On-Page SEO Audit
Private by design
No account needed. What you type stays in your browser unless you ask for an AI suggestion or name a URL to fetch.
Sees what a crawler sees
URLs are fetched anonymously and without running JavaScript, so the result is the HTML a basic crawler gets.
Rules, not opinions
Every check is deterministic. Run the same input twice and you get the same result.
Frequently asked questions
How is this different from the SEO Checker?
The SEO Checker grades the tags in your <head>. This also reads the body: your heading hierarchy, images without alt text, how many internal and external links you have, and roughly how much content is on the page.
Why does it say my page is thin when it looks full?
The audit fetches your HTML without running JavaScript, exactly as a basic crawler does. If your content is rendered client-side, it is invisible here — and invisible to any search engine that does not execute your JavaScript.
Should every page have exactly one H1?
It is the safest convention. HTML5 permits several, and Google says it copes with them, but one H1 removes any ambiguity about what the page is primarily about.
Do images really need alt text for SEO?
Yes, twice over: it is how the image gets understood for image search, and it is what a screen reader announces. Reserve an empty alt attribute for images that are purely decorative.
