SEO Audit & Metadata Checker: Title, Meta, Canonical

What does SEO Audit & Metadata Checker do?

SEO Audit & Metadata Checker audits web pages for on-page SEO and extracts their metadata: title, meta description, canonical, hreflang, Open Graph, Twitter cards, structured data, headings, image alt text, redirects, robots directives and server response time. Every page gets a list of plain-language issues (error, warning or notice) and a 0–100 SEO score.

Audit a list of pages, or turn on crawling to follow links across a whole website (optionally seeded from its sitemap) and get a site summary with duplicate titles, duplicate meta descriptions, the most common issues and the slowest pages. Because it runs on the Apify platform, you can schedule weekly audits, call it through the API, and send results to Google Sheets, Slack, Make, Zapier or n8n.

Why use this SEO audit tool?

• Find what hurts rankings before Google does: missing or duplicate titles, noindex pages, canonicals pointing elsewhere, redirect chains, pages blocked for Googlebot, broken status codes.
• Check social previews: Open Graph and Twitter card tags for every page.
• Validate structured data: schema.org types from JSON-LD and microdata, and invalid JSON-LD blocks.
• Monitor sites on a schedule and compare scores over time.
• Audit many client sites at once for agencies, or run it before and after a site migration.
• Affordable: pay per page audited, a fraction of the price of most audit tools.

How much does an SEO audit cost?

This Actor uses pay-per-event pricing: you pay per HTML page audited. Pages that fail to load, return an error status, are not HTML or are skipped by robots.txt are free. See the Pricing tab for the current price per 1,000 pages. You can set a maximum cost per run; crawling stops cleanly when it is reached.

Tips

• Start small: crawl 50 pages first, then raise the limit.
• Large sites: use Skip URLs matching for tag, search and pagination URLs, and keep depth at 2–3.
• Schedule a weekly crawl and compare averageScore in the site summary.
• Staging sites: turn off Respect robots.txt only for sites you own.

FAQ and limitations

Does it render JavaScript? No. It audits the HTML the server returns, like most search engine crawlers see on the first pass. Content injected later by JavaScript is not included.

Does it measure Core Web Vitals? No. responseTimeMs is the server response time (including redirects), not a Lighthouse score.

Is the title pixel width exact? No, it is an estimate based on average character widths in Google's desktop font.

Does it collect personal data? No emails or phone numbers are extracted. Full structured data is off by default.

Blocked pages? Some sites refuse automated requests (HTTP 403 or 429); these pages are reported with an error and not charged.

Need another check? Open an issue in the Issues tab. Only audit websites you are allowed to crawl.
