Verdict
Choose Google Lighthouse when
- GEO readiness matters to you. Some experimental machine-readability checks, but no full GEO workflow.
- 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 Netpeak Spider when
- Research depth matters to you. Deep crawl and on-page analysis supports technical investigation, though it is not a broad market or backlink research suite.
- Context gathering matters to you. Good first-party/site context and limited competitor extraction.
- Technical SEO matters to you. Comprehensive technical crawler and audit support.
- Team collaboration matters to you. Supports sharing projects/reports and branded client deliverables.
