Website SEO Audit - Broken Links, Meta Tags & Core Web Vitals

Run a full technical and on-page SEO audit of entire websites in one go. Give a list of websites. This Actor reads each site's sitemap and follows its internal links, opening every page in a real Chrome browser. It returns:

• an SEO score out of 100 for every page,
• every problem found, ranked error / warning / notice, with the value that caused it,
• broken links (404, 410, 5xx, unreachable), with the page where each one was found,
• Core Web Vitals lab metrics: LCP, CLS, Total Blocking Time, server response time and page weight,
• duplicate titles and meta descriptions across the site,
• a shareable HTML report per run, ready to send to a client.

It's built for SEO agencies, freelancers, web developers and site owners who need a fast site audit without a monthly SEO tool subscription.

What it checks

Area	Checks
Indexability	HTTP status, redirects, noindex (meta robots and X-Robots-Tag), canonical tag, robots.txt, sitemap.xml
On-page	Title (missing, too long, too short, duplicate), meta description (missing, length, duplicate), H1 (missing, multiple), H2/H3 counts, word count, lang attribute, hreflang
Links	Internal and external links on every page, broken links with anchor text, internal/external link counts
Speed	Largest Contentful Paint, Cumulative Layout Shift, Total Blocking Time, time to first byte, load time, page weight, number of requests
Mobile & security	Viewport meta tag, HTTPS, mixed content
Rich results & social	Structured data types (JSON-LD and microdata), Open Graph tags, Twitter card
Images	Images without alt text

Why use it

• Whole sites, in bulk. Audit hundreds of websites in one run, for example to qualify prospects or monitor client sites every week.
• JavaScript sites included. Pages are rendered in Chrome, so React, Vue and other single-page applications are audited as Google sees them.
• Sitemap and links. It finds orphan pages through the sitemap as well as linked pages.
• Fast link checking. Each unique link is checked once per run, even if it appears on every page.
• Pay per page. There is no subscription: you only pay for the pages audited.

Output

One dataset item per page (shortened):

{
  "url": "https://example.com/about",
  "statusCode": 200,
  "seoScore": 74,
  "errors": 1,
  "warnings": 2,
  "notices": 3,
  "issues": [
    { "id": "broken-links", "severity": "error", "message": "The page links to broken URLs (404, 410, 5xx or unreachable)", "details": "1 broken links" },
    { "id": "description-missing", "severity": "warning", "message": "Missing meta description" }
  ],
  "title": "About us | Example",
  "titleLength": 18,
  "metaDescription": null,
  "h1": ["About us"],
  "canonical": "https://example.com/about",
  "indexable": true,
  "structuredDataTypes": ["Organization"],
  "wordCount": 420,
  "brokenLinks": [{ "url": "https://example.com/old-page", "status": 404, "anchorText": "Our history", "internal": true }],

}

The run's key-value store also contains:

• REPORT: an HTML report per website with the average score, issues by severity, broken links, duplicate titles and descriptions, and the pages to fix first.
• SUMMARY: the same summary as JSON.

You can export the dataset as JSON, CSV, Excel or HTML. You can also call the Actor through the Apify API, run it on a schedule, or use it from Make, Zapier or n8n.

How the score works

Each page starts at 100. Each problem found removes points: 10 for an error, 5 for a warning, 1 for a notice. Use the score to compare pages and track progress over time.

Good to know

• Speed metrics are lab measurements taken from a data center with a real Chrome browser. They are reliable for comparing pages and spotting slow ones, but real visitors (Google's field data) may see different values.
• Some websites, such as LinkedIn, refuse automated link checks. These links are counted as linksUnverified, not as broken.
• Only audit websites you own or have permission to test.

FAQ

Can I audit only a list of pages? Yes. Set "Maximum pages per website" to 1, turn off "Use the sitemap" and list the exact pages.

Should I use desktop or mobile? Google indexes the mobile version of websites, so mobile gives the most relevant results for SEO.
