Verdict
Choose Google Lighthouse when
- Technical SEO matters to you. Useful page-level technical SEO and quality audits, but not a full site crawler.
- Free tools matters to you. Strong free utility value for page audits and regression checks.
- Agent readiness level matters to you. Useful as an automated audit input, but not an autonomous SEO agent workflow.
Verdict
Choose SEO Stuff when
- Keyword research quality for SEO content matters to you. Strong documented keyword metrics, filtering, intent and scale for a lightweight product.
- Research depth matters to you. Useful but focused keyword and backlink research rather than a full enterprise SEO data suite.
- Content execution matters to you. Content execution exists primarily as paid human-edited services, with limited proof of an in-app writing workflow.
- AI-search / GEO matters to you. AI-search visibility and citation optimization are explicit product/service goals across several current pages.
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.
