How to solve “Add Expires headers” of GTMatrix for websites?

When we were checking our website using GTMatrix we got a very poor score from GTMatrix. One of the matrices was this “Add Expires headers” where got F sadly.

Following are the complains:

https://static.com/wp-content/cache/minify/3f101.css
https://fonts.googleapis.com/css?family=Open+Sans%3A400%2C600&ver=5.3.2
https://static.com/wp-content/cache/minify/6ce23.css
https://static.com/wp-content/cache/minify/0f1b5.js

This above issues can be easily resolved by using .htaccess file. Inside the .htaccess file if we add the following line and check again then you will see a significany improvement:


  ExpiresActive on

# Your document html
  ExpiresByType text/html "access plus 0 seconds"

# Media: images, video, audio
  ExpiresByType audio/ogg "access plus 1 month"
  ExpiresByType image/gif "access plus 1 month"
  ExpiresByType image/jpeg "access plus 1 month"
  ExpiresByType image/png "access plus 1 month"
  ExpiresByType video/mp4 "access plus 1 month"
  ExpiresByType video/ogg "access plus 1 month"
  ExpiresByType video/webm "access plus 1 month"

# CSS and JavaScript
  ExpiresByType application/javascript "access plus 1 year"
  ExpiresByType text/css "access plus 1 year"
