Open Score
The open score is a weighted average of four layer scores. It ranges from 0 to 100 and represents how well the site serves AI crawlers.
Layer weights
| Layer | Weight |
|---|---|
| Layer 1 - Crawl Access | 25% |
| Layer 2 - Renderability | 25% |
| Layer 3 - Structured Data | 35% |
| Layer 4 - Advanced | 15% |
Formula
Each layer score is calculated independently, then combined using the weights above:
scoreable = checks where status is not "skip" or "info"layer_score = (passes + warns × 0.5) / count(scoreable) × 100skip and info checks are excluded from the denominator - they do not penalise the score.
Score labels
| Score | Label |
|---|---|
| ≥ 70 | Well optimised for AI |
| 40–69 | Partially AI-ready |
| < 40 | Poorly optimised for AI |
