Q: What is the SEO score based on? A: Weighted scoring across all checks: title optimization (15pts), meta description (10pts), heading structure (10pts), image alt coverage (10pts), link health (10pts), technical SEO (15pts), structured data (10pts), social meta (10pts), and more. Each check has a clear pass/fail with points breakdown.

Q: Can I use this in CI/CD pipelines? A: Yes. Trigger the Actor via Apify API and check results programmatically. Perfect for automated SEO regression testing before deployments. Integrates with GitHub Actions, Jenkins, and any webhook-capable CI system.

Q: Does this check page speed or Core Web Vitals? A: No. This Actor focuses on on-page SEO factors (content, metadata, structure). For performance metrics, use Google PageSpeed Insights or Lighthouse.
