  TTFB directly impacts all subsequent loading metrics.

• high
  Video without captions

  Social media posts with images receive significantly more engagement than text-only posts.

• low
  Broken heading hierarchy

  Heading hierarchy provides a semantic outline of the page content.

• low
  ETag header missing on resources

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

• low
  Excessive inline JavaScript

  Inline JavaScript cannot be cached by the browser and must be parsed and executed every time the page loads.

• low
  Image has empty alt attribute

  If a content-relevant image has an empty alt attribute, search engines cannot understand what the image depicts, and it will not appear in image search results.

• low
  Meta description is too long

  Truncated descriptions cut off your message to potential visitors.

• low
  Social media preview is incomplete

  Incomplete social previews reduce the visual appeal and click-through rate of shared links.
