On-Page SEO Audit – Bulk Meta Tags, Headings & Schema Checker

Audit hundreds or thousands of URLs for on-page SEO in one run. For every page you get a score from 0 to 100, a prioritised list of issues (errors → warnings → notices) and all the raw SEO facts, ready to export to CSV, Google Sheets or your dashboard.

What it checks on each page:

• Title tag: missing, too short or too long, multiple titles. Meta description: missing, length.
• Headings: H1 present or multiple, H1 vs title, skipped heading levels, H1–H6 counts.
• Indexability: meta robots / googlebot, X-Robots-Tag header, noindex/nofollow, canonical (missing, multiple, pointing elsewhere), HTTP status, redirect chains.
• International: <html lang>, hreflang codes and self-reference.
• Structured data: JSON-LD blocks and @type list (Article, Product, FAQPage, BreadcrumbList...), invalid JSON-LD, microdata types.
• Social previews: Open Graph (og:title, og:image...) and Twitter Card tags.
• Content: visible word count, thin content, text-to-HTML ratio.
• Images and links: images without alt text (with a sample list), lazy-loading, internal/external/nofollow links, links without anchor text.
• Tech basics: HTTPS, mixed content, HSTS, compression, HTML size, server response time, viewport, charset, favicon.
• Run summary: average score, duplicate titles and duplicate meta descriptions across all audited pages.

Why this Actor

• 💸 $2 per 1,000 pages. Popular SEO audit Actors charge $10–$40 per 1,000 pages.
• ⚡ Fast and light. Plain HTTP with no headless browser, so a 1,000-page audit takes minutes.
• 🧾 Actionable output. Every issue has a code, a severity and a human-readable message. The Issues view gives one row per issue, perfect for sorting and filtering.
• 🤝 Polite. Respects robots.txt by default, fetches each listed URL once (no crawling), identifies itself, and uses timeouts.
• 🤖 Agent-friendly. Structured JSON that AI agents and automations (Make, Zapier, n8n, MCP) can act on.

Pricing

Pay per event, plus a tiny Actor start fee ($0.00005 per GB of memory):

• Audited page: $0.002 per page ($2 per 1,000 pages), compute included.
• Pages that return HTTP 4xx/5xx, time out, don't resolve, aren't HTML or are blocked by robots.txt are reported but not charged.
• Set a maximum cost per run to cap spend; the Actor stops cleanly when it's reached.

Limitations (honest)

• No JavaScript rendering. The audit sees the HTML as served, which is what most search-engine first passes and all social previews see. Content injected only by client-side JavaScript isn't counted.
• One page per URL, no crawling. Combine with a sitemap extractor for full-site audits. Broken outbound links are not checked; use a broken-link checker for that.
• Not a Lighthouse/Core Web Vitals test. Response time is server time-to-HTML, not page-load metrics.
• Heuristic thresholds (e.g. title 30–60 characters) follow common SEO guidelines and are not search-engine rules.

FAQ

Can I audit a competitor's site? It fetches public pages like a normal visitor and respects robots.txt by default. Use it responsibly and keep concurrency low for small sites.

Can I schedule it? Yes. Run it weekly on your key pages with Apify Schedules and compare scores over time.
