This ensures that they are always in the cache, making them load faster.
Add the following code to your .htaccess file.<\/p>\n\n\n\n
\t# BEGIN Expire headers\n\n ExpiresActive On\n \n # Images\n ExpiresByType image\/jpeg \"access plus 1 year\"\n ExpiresByType image\/gif \"access plus 1 year\"\n ExpiresByType image\/png \"access plus 1 year\"\n ExpiresByType image\/webp \"access plus 1 year\"\n ExpiresByType image\/svg+xml \"access plus 1 year\"\n ExpiresByType image\/x-icon \"access plus 1 year\"\n \n # Video\n ExpiresByType video\/mp4 \"access plus 1 year\"\n ExpiresByType video\/mpeg \"access plus 1 year\"\n \n # CSS, JavaScript\n ExpiresByType text\/css \"access plus 1 month\"\n ExpiresByType text\/javascript \"access plus 1 month\"\n ExpiresByType application\/javascript \"access plus 1 month\"\n \n # Others\n ExpiresByType application\/pdf \"access plus 1 month\"\n ExpiresByType application\/x-shockwave-flash \"access plus 1 month\"\n\n# END Expire headers\n<\/pre>\n\n\n\nCache control headers define files that can be cached by the browser.
Add the code below to your .htaccess file:<\/p>\n\n\n\n
# BEGIN Cache-Control Headers\n\n<filesMatch \"\\.(ico|jpeg|jpg|png|gif|swf|pdf|svg|js|flv)$\">\nHeader set Cache-Control \"max-age=84600, public\"\n\n\n# END Cache-Control Headers<\/pre>\n\n\n\nEntity tags is a mechanism that checks whether the files in the browser cache still match the files on the server. By switching this off, a faster loading time can be achieved. Although the result differs from website to website.<\/p>\n\n\n\n
Add the following code to your .htacess file:<\/p>\n\n\n\n
\tHeader unset ETag\n\tFileETag None\n<\/pre>\n\n\n\nNeutralize image hotlinking<\/h3>\n\n\n\n
Image hotlinking occurs when another website uses your images (they link directly to your image). That creates extra load on your hosting. You can prevent this in some cases by adding the following lines to your .htaccess file.<\/p>\n\n\n\n
Don’t forget to change the domain name to your own domain name.<\/p>\n\n\n\n
RewriteEngine on\nRewriteCond %{HTTP_REFERER} !^http(s)?:\/\/(www\\.)?yourdomainname.com [NC]\nRewriteCond %{HTTP_REFERER} !^http(s)?:\/\/(www\\.)?google.com [NC]\nRewriteRule \\.(jpg|jpeg|png|gif)$ - [NC,F,L]<\/pre>\n\n\n\nStop landing page redirects<\/h3>\n\n\n\n
When using GTMetrix, you sometimes get the following message:
“Avoid landing page redirects for the following chain of URLs”.
This occurs when you have an SSL certificate installed but do not have a direct redirect from HTTP to HTTPS.<\/p>\n\n\n\n
To prevent this, add the following lines to your .htaccess file:<\/p>\n\n\n\n
\t#redirect non-www to www\n\tRewriteEngine On\n\tRewriteCond %{HTTP_HOST} !^www\\.\n\tRewriteRule ^(.*)$ https:\/\/www.%{HTTP_HOST}\/$1 [R=301,L]\n<\/pre>\n\n\n\nOptimize the wp-config.php file<\/h2>\n\n\n\nLimit the number of revisions of wp-config.php<\/h3>\n\n\n\n
There is no single button in WordPress to limit the number of revisions stored in your database. A large number of revisions will mean your website will go slower. Therefore, setting a limit is recommended.<\/p>\n\n\n\n
Add the following code to your wp-config.php file to limit the number of stored revisions to 3:<\/p>\n\n\n\n
define( 'WP_POST_REVISIONS', 3 );<\/pre>\n\n\n\nTo disable it completely, add the following code.<\/p>\n\n\n\n
define( 'WP_POST_REVISIONS', false );<\/pre>\n\n\n\nStop WP-cron<\/h3>\n\n\n\n
WP-cron is allso called “a poor man’s cron”. It ensures that every time someone visits your website, a check is performed on whether there are any pending actions within WordPress. If that is the case, they will be executed immediately.<\/p>\n\n\n\n
Disable this by adding the following code to your wp-config.php file:<\/p>\n\n\n\n
define('DISABLE_WP_CRON', true);<\/pre>\n\n\n\nIf you still want to perform specific cron tasks automatically, you can do this via the crontab.
Create a cron job<\/a> via the control panel with the following code:<\/p>\n\n\n\n*\/30 * * * * curl -sLo \/dev\/null https:\/\/domain.extension\/wp-cron.php?doing_wp_cron<\/pre>\n","protected":false},"excerpt":{"rendered":"Optimize your WordPress website to get the most out of your hosting package.
