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.
- Technical SEO matters to you. Useful page-level technical SEO and quality audits, but not a full site crawler.
Verdict
Choose Textmetrics when
- Content execution matters to you. Strong real-time optimization and rewriting guidance across quality, SEO/GEO and governance dimensions.
- Publishing workflow matters to you. Broad embedded workflow coverage across browsers, Office, CMS and ATS, plus custom connections.
- Context gathering matters to you. Strong organization-specific context through writing guides, policies, tone and automatic content-data collection.
- AI-search / GEO matters to you. Explicit GEO positioning for AI chatbots, with question matching, structure and authority guidance.
