Understanding Page Speed performance scores

For each rule, Page Speed gives specific suggestions for improvement. Page Speed also gives the page an overall Page Speed score.

Understanding scores and suggestions

For each rule, there is a color-coded score (green, yellow, or red).
Here's how to interpret the color-code scores:
  • High priority. These suggestions represent the largest potential performance wins. You should address these items first.
  • Medium priority. These suggestions may represent smaller wins or much more work to implement. You should address these items next.
  • Working fine or low priority. If suggestions are displayed, as indicated by a bold-text rule name, they probably represent minor wins. You should only be concerned with these items after you've handled the higher-priority ones.

Understanding the total score

Page Speed also gives you a total numeric and color-code score. The numeric score indicates how much room for improvement there is for the current page. A high overall score indicates little room for improvement, while a lower score indicates more room for improvement.

NOTE: This is an experimental feature of chrome may cause instability in chrome or Your OS.
