How to Fix the Leverage Browser Caching Warning in WordPress with code

If you’re seeing this warning in Google PageSpeed Insights, you can resolve it by:

1. Adding Cache-Control or Expires headers.
2. Leveraging browser caching for Google Analytics.
3. Minimizing your use of third-party scripts.

You can add Expires headers in Apache by adding the following to your .htaccess file:

## EXPIRES HEADER CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType image/svg "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType application/javascript "access 1 month"
ExpiresByType application/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 1 month"
</IfModule>
## EXPIRES HEADER CACHING ##


Another way, you can improve browser-caching is to add Cache-Control. To add Cache-Control, you need to add the following code in .htaccess file.

# BEGIN Cache-Control Headers


<filesMatch "\.(ico|jpe?g|png|gif|swf)$">
Header append Cache-Control "public" 

<filesMatch "\.(css)$">
Header append Cache-Control "public"

<filesMatch "\.(js)$">
Header append Cache-Control "private"

<filesMatch "\.(x?html?|php)$">
Header append Cache-Control "private, must-revalidate"

How to Enable GZIP Compression in WordPress

How to Enable GZIP Compression in WordPress

Check GZIP Compression Tool

The first and quickest way to check if GZIP compression is enabled on your site is to simply head over to the free Check GZIP compression tool. Simply input your website and click search. It will return the amount that was saved by compressing the page with GZIP. Or it will return an error letting you know GZIP isn’t enabled. As you can see in our test below, we saved 78.28%.

 

Enable GZIP on Apache

The second way to enable Gzip compression is by editing your .htaccess file.  Most shared hosts use Apache, in which you can simply add the code below to your .htaccess file. You can find your .htaccess file at the root of your WordPress site via FTP.

 

 

<IfModule mod_deflate.c>
# Compress HTML, CSS, JavaScript, Text, XML and fonts
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
AddOutputFilterByType DEFLATE application/x-font
AddOutputFilterByType DEFLATE application/x-font-opentype
AddOutputFilterByType DEFLATE application/x-font-otf
AddOutputFilterByType DEFLATE application/x-font-truetype
AddOutputFilterByType DEFLATE application/x-font-ttf
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE font/opentype
AddOutputFilterByType DEFLATE font/otf
AddOutputFilterByType DEFLATE font/ttf
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE image/x-icon
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/xml

# Remove browser bugs (only needed for really old browsers)
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
Header append Vary User-Agent
</IfModule>

<IfModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</IfModule>

Ensure that you add it below the current contents of your .htaccess file. Example below:

Important: Make sure mod_filter is loaded on your server, otherwise the AddOutputFilterByType directive will not work and could cause a 500 error. We recommend checking your error logs if you have any issues with the code below.
