Verdict
Choose Google Lighthouse when
- Technical SEO matters to you. Useful page-level technical SEO and quality audits, but not a full site crawler.
- GEO readiness matters to you. Some experimental machine-readability checks, but no full GEO workflow.
- Agent readiness level matters to you. Useful as an automated audit input, but not an autonomous SEO agent workflow.
Verdict
Choose Looker Studio when
- Team collaboration matters to you. The product explicitly supports sharing with individuals, teams, or the world, real-time collaboration, and embedding.
- Measurement & tracking matters to you. Interactive dashboards and connected Analytics, Ads, and Search Console data provide strong measurement/reporting support, though the pages do not claim native rank tracking.
These tools solve different jobs. Scores are shown against each tool's own category, so the overall grades are not directly comparable. How grades work.
