Why it matters
- Prioritized hint system distinguishes critical issues from nice-to-haves — teams fix the right things first instead of spending hours on low-impact issues.
- Visual site structure maps show how pages link to each other — useful for finding orphaned pages, identifying crawl depth problems, and understanding site architecture.
- Client-ready reports with explanations make it practical for agencies — non-technical clients understand what's wrong and why it matters.
- Explanation-first design educates SEO teams — each issue includes what it is, why it matters, and how to fix it.
