• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Images missing width and height attributes

  Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.

• medium
  Scripts without async or defer

  Synchronous scripts halt HTML parsing while the browser downloads and executes them.

• low
  ETag header missing on resources

  Without ETags, browsers cannot efficiently validate whether cached resources have changed.

• low
  Images missing responsive srcset

  Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.

• low
  Images not using modern format

  WebP images are 25-35% smaller than equivalent JPEG images, and AVIF offers even greater savings.

• low
  Link is named for screen readers but has no anchor text

  Nothing is broken for users.

• low
  Open Graph og:url tag missing

  The og:url tag acts as a canonical for social shares, consolidating likes, shares, and comments to a single URL.

• low
  Title tag is too short

  Short titles often lack the keyword richness needed to rank for target queries.

• low
  Twitter Card meta tag missing

  Twitter Card tags enable rich media previews when your page is shared on Twitter/X.

• low
  WebSite schema markup missing

  Google reads WebSite structured data on the home page when choosing the site name it shows above your results.
