Verdict
Choose Scrunch when
- AI-search / GEO matters to you. Core product is explicitly AI-search visibility, citations, brand presence, model comparison and AI-answer optimization.
- Technical SEO matters to you. Diagnoses AI-bot access, JavaScript, load and structure issues, but does not document a broad traditional technical-SEO crawler.
- Publishing workflow matters to you. Optimizer and page optimization are present, while Core has only basic generation and one page optimization/month; no broad CMS publishing workflow is evidenced for Core.
- Estimated customer scale matters to you. Official homepage states “Trusted by over 500 companies... and agencies,” giving a vendor-reported lower-bound estimate.
Verdict
Choose SpyFu when
- Keyword research quality for SEO content matters to you. Very strong competitor, related-term, intent, and filtering workflow.
- Agent readiness level matters to you. ChatGPT-connected SpyFu GPT plus API access make the product usable by agents, though execution remains bounded.
