Who this is for

Web agencies running a technical check before handing a site to a client, or as part of a monthly retainer.
SEO consultants who need a fast, repeatable audit across many client sites.
Site owners and developers who want to know what broke after a redesign or a migration.
Accessibility reviewers looking for missing alt text, unlabelled form fields, undeclared page language and broken heading structure.

What it checks

Indexing and crawlability

Pages returning 4xx or 5xx errors
Broken internal links (and external ones, optionally)
noindex / nofollow directives — in both the meta tag and the X-Robots-Tag header
Missing, mismatched or malformed canonical tags
Redirect chains

On-page SEO

Missing, too short or too long <title>
Missing, too short or too long meta description
Duplicate titles and descriptions across the whole site
Missing or duplicated H1
Broken heading hierarchy (h1 → h3, or a page that starts at h3)
Thin content

Accessibility

Images without an alt attribute (alt="" is correctly treated as intentional, not as a fault)
Missing lang attribute on <html>
Links with no accessible name
Form fields with no associated label

Mobile, performance and security

Missing or malformed viewport meta tag
Slow server response times
Heavy pages
Pages served over HTTP instead of HTTPS
Mixed content — HTTP resources loaded on an HTTPS page

Rich results

Missing JSON-LD structured data
JSON-LD blocks that fail to parse

What you get

A summary (SUMMARY in the key-value store) built to be read in ten seconds:

{
  "auditedSite": "https://example.com/",
  "overallScore": 74,
  "pagesAnalyzed": 248,
  "pagesWithErrors": 6,
  "brokenLinksFound": 14,
  "criticalIssues": 6,
  "majorIssues": 91,
  "minorIssues": 203,
  "whereToStart": [
    { "code": "broken_link", "label": "Broken links", "severity": "critical", "affectedPages": 14 },
    { "code": "missing_meta_description", "label": "Missing meta description", "severity": "major", "affectedPages": 68 }
  ],
  "pagesToFixFirst": [
    { "url": "https://example.com/old-page", "score": 20, "issueCount": 9 }
  ]
}

The list of broken links is stored alongside it, under BROKEN_LINKS.

A dataset, one row per page: URL, HTTP status, score out of 100, title, meta description, H1 count, images without alt, response time, crawl depth, and the full list of issues found with severity and explanation.

{
  "url": "https://example.com/pricing",
  "statusCode": 200,
  "score": 74,
  "title": "Pricing | Example",
  "metaDescription": null,
  "h1Count": 1,
  "imagesWithoutAlt": 0,
  "issues": [
    {
      "code": "missing_meta_description",
      "severity": "major",
      "message": "No meta description: the search engine then picks a snippet at random."
    }
  ]
}

Every issue carries a stable code you can filter on, a severity, and a message written for a human. Export to Excel, CSV or JSON, or pull it from the API to feed your own report template.

Report language. Field names and issue codes are always English, so your integrations stay stable. The message and label texts follow the Report language setting — English by default, French available.

How it was verified

The audit was tested against 150 generated sites whose defects were known in advance — around 1 000 pages and 8 600 injected issues across three independent draws. Every injected defect was found, and no non-existent defect was reported:


Recall (real defects actually found)	100 %
Precision (reported defects that are real)	100 %

Plus 84 automated tests covering each rule, the crawl boundaries, and robots.txt compliance.

That test bench caught a real bug before release: pages returning 403 were silently skipped by the crawler's block-detection and never appeared in the report. A site with a protected section would have produced an incomplete audit without saying so.

Scoring

Each page starts at 100 and loses points per issue: 25 for a critical, 8 for a major, 2.5 for a minor. The overall score is the average across pages.

It is deliberately simple and documented, so you can explain it to your own client instead of pointing at a black box.

Settings

Setting	Default	What it does
Website URL	—	The site to audit. Required.
Maximum pages	100	How many pages to crawl. This is what you pay for.
Maximum crawl depth	5	How many clicks from the start page. `0` audits only that page.
Include subdomains	off	Also audit `blog.example.com`, `shop.example.com`.
Check external links	off	Also verify outbound links still resolve. Slower.
Parallel requests	5	Lower it if the server is small or rate-limited.

Tip: run it first with Maximum pages = 20 to see the shape of the results and estimate what a full audit will cost.

How it behaves

robots.txt is always respected. There is no setting to override it, by design. Pages excluded by robots.txt are counted and reported so you know what wasn't seen.
No anti-bot circumvention. No CAPTCHA solving, no proxy rotation to defeat rate limits, no spoofing. If a site blocks automated access, this Actor reports the failure rather than working around it.
Rate limited by default — 5 parallel requests, 20 maximum. It won't hammer a small server.
No personal data is collected. No email addresses, no phone numbers, no author names, no comments. Only technical characteristics of the documents. mailto: links are ignored entirely.
No browser — pages are fetched and parsed as HTML, which is roughly twenty times cheaper in compute than driving a full browser. That saving is passed on in the price.

Response time is measured end to end, network latency included. A first connection to a distant server can cross the slow-response threshold without the server being at fault — the report says so rather than letting you blame the wrong thing. Re-run the audit before acting on that specific finding.

One consequence worth knowing: because there is no browser, content injected purely by client-side JavaScript is not seen. For most sites this doesn't matter — search engines index the served HTML too — but if your site is a single-page application that renders everything client-side, this tool will report thin content for pages that look full in a browser.

Intended use

This Actor is for auditing websites you own, manage, or are authorised to analyse. That is what it is built and priced for.

Pricing

Pay per event: a small fixed charge when the audit starts, then a charge per page audited. You pay for what you crawl — no subscription, no minimum.

Set Maximum pages to cap your spend exactly. If your run hits your account's spending limit mid-audit, the Actor stops cleanly and still gives you the report for the pages it completed, with a note saying so.

Support

Found a false positive, or a check you'd expect that isn't here? Open an issue on the Actor's issues tab with the URL and what you expected — that's the fastest way to get it fixed.
