Verdict
Choose Google Trends when
- Free tools matters to you. The core official site is publicly usable and presents no paid plan or paywall in the fetched page.
Verdict
Choose SEOTesting when
- AI-search / GEO matters to you. Direct generative-search visibility workflow: LLM pages, prompt clues, content evaluation and before/after LLM tests.
- GEO readiness matters to you. Strong AI-answer visibility readiness through question fan-out, semantic coverage, trust, extractability and persona evaluation.
- Content execution matters to you. Provides concrete AI-assisted content evaluation and clarity/structure fixes, plus tests to validate changes, but does not publish content.
- Technical SEO matters to you. Narrow technical monitoring for sitemaps and robots.txt, plus Search Console data; not a complete crawler/audit platform.
