Verdict
Choose Google Lighthouse when
- Value accessibility matters to you. Excellent access because the core utility is free, open source, and built into common web workflows.
- 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 Moz Pro when
- Keyword research quality for SEO content matters to you. Strong keyword discovery, intent, SERP, competitive, and prioritization data for content planning.
- Research depth matters to you. Strong breadth of SEO research workflows across keywords, competitors, SERPs, domains, and brand authority.
- AI-search / GEO matters to you. Dedicated AI Visibility dashboards track prompts across GPT, Gemini, Google AI Mode, and Perplexity.
- Estimated customer scale matters to you. Moz publishes a large marketer-trust claim, but it is marketing evidence rather than an audited active-customer count.
