Free SEO Audit and Website Audit Tool (No Signup)

Most free SEO audits are a lead form with a progress bar attached. You get a number, a list of scary red items, and a prompt to book a call to find out what they mean.

This one asks for a URL and an email address to send the results to. No account, no call, and the results are on screen straight away. You get a report page with a score, the findings ranked by how much they actually cost you, the evidence behind each one — and, unusually, a list of everything it did not check.

That last part is the difference worth understanding before you run it.

What the free scan actually checks

The free scan reads your site and a handful of public records about it:

• Your homepage, fetched twice — once the way a plain crawler sees it, once with a browser user agent. Sites that open only for real browsers are invisible to most AI crawlers, and comparing the two responses is how that shows up.
• robots.txt, including the directives aimed at AI crawlers specifically.
• Your XML sitemaps — whether they exist, parse, and are reachable.
• /.well-known/ files, including llms.txt — see what llms.txt is and whether it does anything.
• DNS and domain registration, including SPF, DKIM and DMARC — the records that decide whether your email is trusted.
• Your TLS setup — certificate, protocol, and how the connection is negotiated.
• Wikidata, for whether an independently verified record of your business exists.
• Google Safe Browsing, for whether your site is flagged as unsafe.
• Ahrefs Domain Rating, as a rough measure of backlink authority.
• A language-model read of your page text — whether your category and offering are stated clearly enough for a machine to extract them.

Every result names the page or record it came from. If a finding says your robots.txt blocks an AI crawler, the report shows you the line.

What it deliberately does not check

This is the part most free audits leave out, and the reason theirs often score you higher than a paid one would.

The free scan does not:

• Crawl past your homepage
• Render the page in a real browser
• Run PageSpeed Insights or pull Chrome UX Report field data — so it does not measure your site speed at all
• Check your Google Business Profile, Trustpilot reviews, or Companies House record
• Look at how you currently appear in search results
• Check Common Crawl, Tranco, Mozilla Observatory, certificate history, or the Wayback Machine
• Ask AI models what they already know about your brand

That last one is worth being blunt about, because it is the measurement people come here for. The free scan has a model read your page; it does not ask three models, twice each, what they can recall about your business without being shown it. That probe costs real money per run, so it belongs to the deep audit.

These are not oversights. They are the sources that cost money, take minutes rather than seconds, or both.

Why the free score is capped below 100

A score that starts at 100 and subtracts for problems quietly rewards a scan for the checks it never ran — which is how a free audit ends up flattering a site that a thorough one would fail.

Every run here is scored against the whole 273-check list, not just the checks it managed to run. The free scan can only award the share it actually verified, so it reports a provisional ceiling rather than a settled score, and carries no letter grade. The report then lists the areas it skipped and how many checks each holds.

The full arithmetic — severity weights, ceilings, the coverage formula — is written out on the methodology page.

What each result means

Every check settles into one of five states, and they are not interchangeable:

• Pass — the expected signal was found.
• Warning — a real but lower-severity issue, worth fixing after the urgent ones.
• Fail — a confirmed problem, with evidence attached.
• Not measured — no conclusion was reached. A source timed out, refused us, or errored. On a full scan this is excluded from your score rather than counted against you.
• Does not apply — the check is irrelevant to your site, like shop checks on a site that sells nothing.

The distinction between fail and not measured is the one that matters. A failure is something to fix. Missing evidence is something to investigate, or ignore. Reports that collapse the two are telling you that your site is broken when what actually happened is that an API was down.

Free scan or deep audit

Run the free scan first. It is genuinely enough to find a blocked crawler, a broken sitemap, a missing business record or an unreadable homepage — and those are the problems that cost the most visibility for the least effort to fix.

How to spot a free audit that is wasting your time

Having built one, these are the tells:

• One score, no arithmetic. If the page cannot tell you how the number is calculated, the number is decoration.
• Everything is urgent. A report where every item is red has not prioritised anything, which is the only genuinely useful thing a report does.
• Missing data shown as failure. If their API failed, that is not a fault on your site.
• No page or source named. “Improve your structured data” is not a finding. “Your /services/ page declares a Product with no offers block” is.
• The findings appear after the form. If the results exist, they can be shown. A gate means the results are the bait.

After you run it

Fix confirmed failures first, worst severity at the top — the report already ranks them by impact rather than by section order.

Then re-run it. Comparing two reports of the same site is the fastest way to confirm a fix actually landed, and the free scan exists partly so you can. There is a fair-use limit of five scans an hour, which is well past what checking your own work needs.

If you are comparing your site against a competitor’s, run the same tier on both. A free scan against a deep scan is not a comparison.
