SEO On-Page Audit: title, meta, H1, canonical, OG & schema in one pass

Audit any list of page URLs for on-page SEO signals — title and meta description (with lengths), H1/H2, canonical, hreflang, Open Graph, Twitter cards, JSON-LD types, internal/external/nofollow link counts, images missing alt, approximate word count, plus a short issues list. Paste URLs you already have (or pipe output from the Sitemap Scraper); the Actor fetches only those pages. No site-wide crawl, no login, no paywall bypass. ~$1.50 per 1,000 pages audited; failed or unreachable URLs are free.

What you get from the SEO On-Page Audit

• Core tags — title, metaDescription, metaRobots, metaViewport, charset, html lang, with character lengths for title and description.
• Canonical & hreflang — canonical, canonicalMatchesUrl, and every hreflang alternate found in <link rel="alternate">.
• Social + structured data — Open Graph (og:*), Twitter card tags, and JSON-LD @type values (raw snippet truncated if huge).
• Structure signals — H1/H2 texts and H1–H6 counts, internal vs external vs nofollow link counts, images total / missing alt, approximate body word count.
• Actionable issues — short flags like missing title, title too long >60, multiple h1, missing canonical, missing meta description.

How to configure the SEO On-Page Audit

1. Paste page URLs, one per line (or pass [{ "url": "…" }] from another Actor / sitemap export).
2. Optional: raise Max URLs (default 100, max 5000) or turn off Respect robots.txt.
3. Run. Every page that returns an HTTP status (including 4xx/5xx) is charged; unreachable / robots-blocked rows are free.

Example input

{
  "startUrls": ["https://example.com", "https://apify.com"],
  "maxUrls": 100,
  "respectRobotsTxt": true
}

Setting	Default	Notes
startUrls	(required)	Pages you supply — not discovered via search
maxUrls	100	Hard cap per run (max 5000)
respectRobotsTxt	true	Skip disallowed paths
maxConcurrency	5	Pages in parallel (keep low for politeness)

Common use cases

• Bulk SEO QA — check title/meta/H1/canonical across a sitemap export before a migration or redesign.
• Agency reporting — attach issues columns to client sheets without opening each URL by hand.
• Content ops — find missing OG/Twitter tags and thin pages (low wordCount) on a URL list.
• Pipeline with TinyRex — Sitemap Scraper → this Actor → export CSV; pair with Contact Details Extractor or Tech Stack Detector for enrichment.

Pricing (failed = free)

Pay per event:

• Page audit (page-audit): ~$0.0015 per page that returns an HTTP status (including 4xx/5xx — you still get the audit row). ≈ $1.50 / 1k pages.
• Free: network failures / unreachable hosts (statusCode 0), robots.txt blocks.

Bronze/Silver/Gold tier discounts apply on the Store. Set a max cost per run; the Actor stops gracefully when it is reached.

Limitations

• Public HTML only. Heavy JS-rendered titles/meta may be missed (no headless browser).
• Datacenter IP blocks may need a proxy.
• Issue rules are heuristic defaults (title ≤60, description 50–160, single H1) — adjust your process if your style guide differs.

FAQ — SEO On-Page Audit

How do I audit every URL in a sitemap? Run Sitemap Scraper first, then pass its url field into startUrls (string list or { url } objects). Cap with maxUrls if needed.

Do 404 pages cost money? Yes — if the server responds with a status code, you get a dataset row (statusCode, issues) and pay the page-audit event. Unreachable hosts (DNS/timeout) are free.

Does it respect robots.txt? Yes by default (respectRobotsTxt: true). Disallowed URLs are skipped, recorded with an error, and not charged.

Is this a full site crawl? No. It only fetches the URLs you supply. For site-wide coverage, feed it a sitemap export.

Does it work with AI agents / MCP? Yes. Connect Claude, Cursor, VS Code, n8n or any MCP client to https://mcp.apify.com?tools=tinyrex/seo-on-page-audit and ask e.g. "Audit on-page SEO for https://example.com and https://apify.com".
