SEO health is a 0–100 score Crawlinx computes from 157 technical checks run on every crawled page — indexability, titles and meta descriptions, canonical and hreflang correctness, internal linking, redirects, broken links and Core Web Vitals signals. A site scores high only when the whole crawl is clean, so a single median hides a spread worth reading below.
