This is a structured diagnostic tool for identifying SEO problems across crawlability, indexation, on-page elements, and technical performance. It runs through a methodical checklist covering robots.txt issues, canonical conflicts, Core Web Vitals, mobile friendliness, and content quality signals, then outputs a weighted health score from 0 to 100 with categorical breakdowns. The scoring model is transparent about severity deductions and confidence levels, which prevents the usual black-box SEO tool problem. Use it when you need an evidence-based audit report rather than vague recommendations. It won't implement fixes unless you ask, and it gates the audit behind context questions about your site type and goals, which saves time on irrelevant checks.
