Scoring principles
- Evidence-earned: dimensions start at 0, not free 40–70 baselines.
- Separate score, evidence coverage, and confidence on every result.
- Critical caps (no CTA, noindex, no clear offer) prevent cosmetic As.
- Single-page HTML overall max 88 — rare A grades need multi-source proof.
- Findings include observed evidence, example, owner, and validation steps.
- Scores are LoudScale models — not search-engine or ad-platform truth.
- Actual AI mentions require prompt tests (not the readiness checker alone).
- Content Architecture Gap Checker crawls sitemap + internal pages (capped) — not keyword demand.
