Score at a glance

The Crawlibri SEO health score is a global indicator from 0 to 100 reflecting the technical state of your site.

How it is calculated

Each detected issue carries a weight based on its severity:

Type Weight Examples
Critical error High Missing title tag, noindex page, 404 error
Warning Medium Title too long, missing meta description, image without alt
Info / improvement Low Missing H2, thin content

The formula calculates the ratio between points lost and the maximum possible, scaled to 100.

Interpretation

Score Status
80 – 100 ✅ Excellent — technically optimized site
60 – 79 🟡 Good — a few improvements to make
40 – 59 🟠 Average — notable issues
< 40 🔴 Critical — urgent action recommended
