- highSlow server response time (TTFB > 3s)
Page speed is a confirmed Google ranking factor, and TTFB is the foundational component.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- mediumImages missing width and height attributes
Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.
- mediumLink has empty anchor text

The og:url tag acts as a canonical for social shares, consolidating likes, shares, and comments to a single URL.
- lowX-Content-Type-Options header missing
