Why Scavio Wins
- Ahrefs Starter at $29/mo is the best value for non-developers who want a dashboard with keyword explorer, site audit, and backlink checker. If you prefer a GUI over an API, Ahrefs wins.
- DataForSEO is cheaper per query ($0.002 vs $0.005) and has backlink + keyword APIs. For developers who only need SEO data, DataForSEO offers more depth at lower cost.
- Scavio's advantage for light users: 500 free credits/mo often covers the entire workload. For developers running 50-100 checks per month, Scavio costs literally nothing.
- The choice comes down to: need a dashboard? Ahrefs Starter. Need an API with backlinks? DataForSEO. Need multi-platform search data with agent support? Scavio.
