Verdict
Choose InLinks when
- Free tools matters to you. Offers public entity and audience tools with limited daily use without login, plus a free account tier.
- Estimated customer scale matters to you. First-party site claim indicates meaningful adoption, but it is a marketing claim without methodology or independently verifiable customer segmentation.
- Technical SEO matters to you. Meaningful schema and internal-link technical implementation, but no broad crawl/indexation or technical-audit suite is documented.
Verdict
Choose Keyword Insights when
- GEO readiness matters to you. International SERP controls and multi-language writing, without a dedicated GEO score.
- Publishing workflow matters to you. Brief-to-write-to-export plus native WordPress.
- Measurement & tracking matters to you. Ranking tracking, SERP analysis and GSC exist; longitudinal dashboards unclear.
- Agent readiness level matters to you. API and Claude skill support agentic clustering, intent, briefs and writing.
