SEO Audit Tool & Website Crawler – Website SEO Checker

Crawl any website and get an SEO audit of every page: title and meta description (text and length), H1 and H2, canonical, noindex, language, viewport, Open Graph, word count, images without alt text, broken links, redirects and slow pages. Each page gets a list of issue codes and a 0-100 SEO score, and titles and descriptions used on more than one page are flagged as duplicates. Built for SEO audits, agencies checking client sites on a schedule, site migrations, content teams and AI agents. A lightweight Screaming Frog alternative you can run from the API.

What you get

• One row per page with every on-page SEO fact: title, title_length, meta_description, meta_description_length, h1, h1_count, h2_count, canonical, meta_robots, x_robots_tag, lang, has_viewport, has_og_tags, word_count, images, images_missing_alt, internal_links, external_links.
• Technical facts: HTTP status, redirects, final URL, response time and click depth from the start page.
• Issue codes and a score per page, e.g. missing_meta_description, title_too_long, duplicate_title, missing_h1, noindex, canonical_elsewhere, broken_links, thin_content, images_missing_alt, slow_response.
• Broken links per page: every link and image the pages point to is checked (optional), and each page lists the broken ones it contains.
• Site summary in the run's key-value store (SUMMARY): pages audited, average score and how often each issue occurs.

Field	What it does
startUrls	Start page of each site, e.g. https://example.com/.
maxPages	Pages to audit per site, 1 to 10,000. Default 30.
checkBrokenLinks	Also check every link and image the pages point to. Default on.
maxLinksPerSite	Most extra URLs to check for broken links per site. Default 2,000.

Pricing

Pay per event, no subscription:

• $2 per 1,000 pages audited ($0.002 per page).
• $0.0005 per extra link checked for the broken-link report (links to other sites, images, pages beyond your page limit); each URL is checked once per site. Turn checkBrokenLinks off to skip it.
• $0.005 per run start.

Examples: a 30-page site with 200 extra links costs about $0.17. 1,000 pages without the link check cost about $2.01. Cap the cost of a run with the maximum charge setting; the Actor stops when the budget is used.

How it works

• Plain HTTP requests with an honest User-Agent; no browser, no proxies.
• Only pages on the same domain are crawled, only where the site's robots.txt allows it, and pages marked nofollow are not followed.
• At most 2 requests at a time per website, to stay polite.
• Pages that build their content with JavaScript are audited as the server sends them, so text and links added later by scripts are not seen.
• Only SEO facts are stored: no page text, e-mail addresses or phone numbers.

Good to know

• A 30-page site usually takes 20 to 70 seconds, depending on how fast the site answers.
• Run it on a schedule to catch new SEO issues, from the API, n8n/Make/Zapier, or from AI agents through MCP (rowfeed-seo-mcp).
