What Crawlmark measures
Every scan produces two independent scores and a stance classification.
Blocking Score (0–100)
How effectively the site blocks AI crawlers. Calculated from agent-level robots.txt rules, llms.txt presence, and WAF detection.
Stance
OPEN / MIXED / BLOCKING / UNKNOWN - derived from the ratio of blocked to total known AI agents in robots.txt.
