Free tool — no signup

Free SEO audit of any page.

Enter a URL and get a 0–100 score, a letter grade, and a plain-English list of what is costing you search traffic — meta tags, headings, speed signals, mobile, security, content, schema and whether AI crawlers can read the page at all. Your result is a public page you can share with a client.

What you get, and what it costs

An SEO audit is an inspection of what a search engine sees when it loads your page: the tags that describe it, the structure that organises it, the weight that slows it down, and the rules that decide whether a crawler is allowed in. This one runs 36 of those checks on the URL you enter and scores the result out of 100.

Free and public: the score, the grade, the AI-written summary, and the six category scores. That page lives at a permanent shareable link and needs no account. Behind an email: the full issue list with a specific fix written for each one. Behind a plan or the 14-day trial: crawling every page of a site rather than one, re-checking it on a schedule, and turning the result into a branded client report.

The free tool audits a single page. If you have seen a “free full-site audit” elsewhere on this site, that phrasing was wrong and we have corrected it — a whole-site crawl costs us money per page, so it sits inside the trial rather than in the open tool.

What gets checked

36 checks, six weighted categories

These are the same checks the paid crawler runs on every page of a client site — the free tool just runs them once.

Meta tags

20%

Title tag length, meta description, Open Graph tags for link previews, and the canonical tag that tells Google which URL is the real one.

Headings

15%

Whether the page has exactly one H1, whether that H1 reads like a headline rather than a fragment, and whether the heading levels skip a rung.

Speed signals

25%

Server response time, HTML weight, image count and render-blocking scripts in the head. These are source-level signals — they are not a Lighthouse or field Core Web Vitals score.

Mobile

15%

The viewport meta tag, and fixed-width elements wide enough to force a horizontal scroll on a phone.

Security

10%

HTTPS, and mixed content — http resources loaded on an https page, which browsers block or flag.

Content & AI visibility

15%

Word count, alt text coverage, internal links, robots.txt, structured data, llms.txt and whether the AI crawlers (GPTBot, PerplexityBot, ClaudeBot, Google-Extended) are allowed to read the page at all.

Those percentages are our audit methodology — how we weight the categories when producing a single number. They are not measured Google ranking weights, and no tool can honestly claim to know those.

Straight answers

What this audit cannot tell you

Every checker has a boundary. Here is ours, so you know when to reach for something else.

  • It reads the served HTML. Content that only appears after JavaScript runs is not counted — which is also roughly what a crawler sees on its first pass.
  • The speed checks are source-level proxies: response time, HTML weight, image count, blocking scripts. They are not Lighthouse, and they are not field Core Web Vitals from real visitors.
  • It does not check backlinks, keyword rankings or search volume. Those need third-party data, and they live in the paid product rather than the free tool.
  • A high score does not mean you rank. It means the page has no obvious mechanical problems — which is the floor, not the ceiling.

FAQ

Questions people actually ask

Is the SEO audit really free?+
Yes, and there is no signup to see your result. Enter a URL, wait about 30 seconds, and you get a 0–100 score, a letter grade, a plain-English summary and a category-by-category breakdown at a public link you can share. Asking for your email unlocks the full issue list with the fix for each one — that is the only gate on the page.
Does it audit my whole site or just one page?+
The free audit checks one page — the exact URL you enter, which is usually the homepage. That is a deliberate limit, not a bug: crawling a whole site costs real money per page. Multi-page crawling (200–500 pages depending on plan, with a per-page issue list and a worst-pages table) is part of the product you get on the 14-day free trial, which also needs no card.
What does it actually check?+
36 checks in six weighted categories — meta tags, headings, speed signals, mobile, security, and content plus AI visibility. They are listed in full further up this page, and this post walks through the reasoning behind each one.
Is the score a Google ranking score?+
No, and no tool's is. The category weights are our audit methodology — our view of what matters most on a page — not measured Google ranking factors. Treat the score as a prioritised to-do list: it tells you what to fix first, not what position you'll land in.
Can I run it on a competitor's site?+
Yes. Every audit is a public page at /seo-audit/their-domain.com, so agencies routinely run it on a prospect before a pitch. Inside the product you can also add competitors properly and get a side-by-side category comparison against your own crawl.
Does it check whether ChatGPT and Perplexity can see my site?+
Partly. The free audit checks the mechanical prerequisites — whether AI crawlers are blocked in robots.txt, whether llms.txt exists, whether structured data is present. Whether an AI assistant actually names your brand in an answer is a different question, and it has its own free tool: the AI visibility checker.

One page is free. The other two hundred are a trial away.

The 14-day trial crawls a whole client site, re-checks it weekly, writes the fixes, and hands you a report with your logo on it. No card, nothing to cancel.
