• Open Graph Tags: Facebook/social sharing meta tags
• Schema.org Structured Data: JSON-LD detection

• Rule-Based Scoring: 0-100 SEO score calculated from detected issues (no AI needed)

Optional AI Enhancement

Use Cases

• Pre-launch audits: Check new websites before going live
• Competitor analysis: Audit competitor sites for SEO insights
• Regular monitoring: Periodic health checks of your web properties
• SEO agencies: Batch audits for client onboarding
• Developers: Quick technical SEO validation in CI/CD pipelines

Pricing

This Actor uses Pay-per-Event pricing:

• Actor Start: FREE — no charge to start the run
• Successful Audit: $0.08 per successfully audited page
• Failed pages: FREE — no charge if a page cannot be accessed or times out
• No AI costs: Built-in rule engine is free; optional AI enhancement is billed separately via your own Kimi API key (not included in Actor pricing)

A typical 10-page audit costs $0.80 (if all pages succeed). Failed or timed-out pages are not charged.

Requirements

• No API key required for core SEO audit functionality
• Optional: Set KIMI_API_KEY environment variable if you want AI-enhanced recommendations (set useAI: true in input)

Limitations

• Cannot audit JavaScript-rendered SPAs (React, Vue, Angular) — static HTML only
• Broken link check limited to 15 links per page (performance optimization)
• Page fetch timeout: 15 seconds per page
• SSL check requires port 443 to be open
• AI enhancement requires valid KIMI_API_KEY and may fail gracefully (falls back to rule-based scoring)

Support
