Speed Up WordPress without a Plugin



There are so many ways to speed up your WordPress site but many of them involve installing this plugin or that one, having to set it all up and hoping that it doesn’t cause a conflict somewhere else down the line.

But did you know that you can optimize WordPress to a certain extent without having to install a plugin? I wouldn’t recommend this for beginners because it involves editing the .htaccess file, wp-config and php.ini file.

Here goes.

Step 1 – Back up your website

Before you make any changes to any file or install any plugin, you should always back your website up. If things go wrong and you haven’t done this, you stand a good chance of losing the lot.

Step 2 – Use Google PageSpeed Insights to See Your Current Page Speed Score

Self-explanatory, do write down the pertinent information form this so you can compare it later

Step 3 – Open .htaccess

You will need an FTP client to do this as the file is in your website’s root directory. You need to enable browser caching and once you have done that, save it and then check the front-end of your website to make sure it all still works.

What we are doing is enabling Expire Headers so insert the following code into the file:

# BEGIN Expire headers
ExpiresActive On
ExpiresDefault “access plus 5 seconds”
ExpiresByType image/x-icon “access plus 2592000 seconds”
ExpiresByType image/jpeg “access plus 2592000 seconds”
ExpiresByType image/png “access plus 2592000 seconds”
ExpiresByType image/gif “access plus 2592000 seconds”
ExpiresByType application/x-shockwave-flash “access plus 2592000 seconds”
ExpiresByType text/css “access plus 604800 seconds”
ExpiresByType text/javascript “access plus 216000 seconds”
ExpiresByType application/javascript “access plus 216000 seconds”
ExpiresByType application/x-javascript “access plus 216000 seconds”
ExpiresByType text/html “access plus 600 seconds”
ExpiresByType application/xhtml+xml “access plus 600 seconds”
# END Expire headers
# BEGIN Cache-Control Headers

Header set Cache-Control “public”

Header set Cache-Control “public”

Header set Cache-Control “private”

Header set Cache-Control “private, must-revalidate”
# END Cache-Control Headers

Step 4 – Limit the Number of Post Revisions

WordPress, by default, stores every change made to your posts and pages and having too many of these can cause a serious slow-down in your website. In the root directory of your WordPress installation, find the wp-config.php file and add this code:

/**Limit Post Revisions**/
define( ‘WP_POST_REVISIONS’, 3);

Or, you could set your site so it stores no post revisions, in which case, your code would be:

define( ‘WP_POST_REVISIONS’, false);

Step 5 – Find Your PHP.INI file

The location of this will depend on your host so have a look in the host control panel for something like CGI PHP Scripts or just ask your host where it is. When you have it, you are going to enable GZip with the following code.
First, find this line in the file:

zlib.output_compression = Off

Change Off to On

Now look for this line:

zlib.output_compression_level = 6

Most likely your level number will be different so set it to 6. Save and check your website front-end – you should already be seeing a significant increase in speed.

Step 6 – Retest on PageSpeed Insights

How does your new score compare to the old one?

Seriously, you can spend days, weeks trying to speed up your website with all sorts of tools and, in all honesty you should do it. But for now, to see an immediate increase, these steps will work, speeding up your WordPress website quite considerably, inside of about 10 minutes and with no plugins in site.

How to Disable Emojis in WordPress



emoji wordpress

To make your WordPress website load faster and perform better, there are plenty of tweaks that you can do. One of the easiest is to stop emojis from loading on your website.

These are used for expression emotions or ideas and, while they may be good fun, you need to consider if they are necessary. They do add to the page load time which, if they are not necessary, is not good news.

Why? Because they add another HTTP request to load a file called wp-emoji-release.min.js and that request will load on all individual pages of your site.

Disabling Emojis

You can do this in a couple of ways, using code or using a plugin.

Using a Plugin

If you choose to do it this way you can use a free plugin by the name of Disable Emojis. It is a lightweight plugin, so it won’t have too much effect and it removes the additional JS file for supporting Emojis in older browsers. Download it in the same way as you would any other WordPress plugin.

You could also use another free plugin called Emoji Settings or a premium plugin called perfmatters.

Using Code

If installing another plugin on your WordPress site doesn’t appeal to you, you can down the code route. All you need to do is edit the functions.PHP file of your theme with the following code.

NOTE – not to be done if you are not experienced. Making edits to source code can seriously mess up your website if you do it wrong!

Here’s the code:

* Disable the emoji’s
function disable_emojis() {
remove_action( ‘wp_head’, ‘print_emoji_detection_script’, 7 );
remove_action( ‘admin_print_scripts’, ‘print_emoji_detection_script’ );
remove_action( ‘wp_print_styles’, ‘print_emoji_styles’ );
remove_action( ‘admin_print_styles’, ‘print_emoji_styles’ );
remove_filter( ‘the_content_feed’, ‘wp_staticize_emoji’ );
remove_filter( ‘comment_text_rss’, ‘wp_staticize_emoji’ );
remove_filter( ‘wp_mail’, ‘wp_staticize_emoji_for_email’ );
add_filter( ‘tiny_mce_plugins’, ‘disable_emojis_tinymce’ );
add_filter( ‘wp_resource_hints’, ‘disable_emojis_remove_dns_prefetch’, 10, 2 );
add_action( ‘init’, ‘disable_emojis’ );

* Filter function used to remove the tinymce emoji plugin.
* @param array $plugins
* @return array Difference betwen the two arrays
function disable_emojis_tinymce( $plugins ) {
if ( is_array( $plugins ) ) {
return array_diff( $plugins, array( ‘wpemoji’ ) );
} else {
return array();

* Remove emoji CDN hostname from DNS prefetching hints.
* @param array $urls URLs to print for resource hints.
* @param string $relation_type The relation type the URLs are printed for.
* @return array Difference betwen the two arrays.
function disable_emojis_remove_dns_prefetch( $urls, $relation_type ) {
if ( ‘dns-prefetch’ == $relation_type ) {
/** This filter is documented in wp-includes/formatting.php */
$emoji_svg_url = apply_filters( ’emoji_svg_url’, ‘’ );

$urls = array_diff( $urls, array( $emoji_svg_url ) );

return $urls;

It’s a bit long but it will do the job and you should find your website pages load significantly faster now.

Again, I must stress, if you are not comfortable with editing code, either go down the plugin route or let a developer do the job for you.

And don’t forget to back up your website before you do anything, just in case it does all go wrong.

Remove Query Strings from Static Resources



remove query strings from static resources warning

When it comes to improving WordPress performance and speed, one of the more commonly asked questions by more experienced users is, can query strings be removed from static resources?

The answer to that is yes, they can. Usually, the JS and CSS files for your WordPress website will contain the version of the file at the end of the URL, for example, ‘ ver=4.5’.

Some servers can’t cache a query string even if the header, cache-control: public is there and this means that getting rid of these strings can provide some small measure of improvement to caching which, in turn, speeds up your website a little.

If you use GTMetrix or Pingdom, sometimes you will see a warning pop up that tells you to remove these strings, so that’s what we are going to do here.

WordPress developers often use file versioning as well so that, when you get around to updating your plugins, you won’t need to flush out the cache.

For example, if a developer releases an update that changes style.css? ver=4.5’ to ver=4.6, it gets seen as a brand-new URL and, as a result, does not get cached.

Removing a Query String from a Static Resource

You can do this in a couple of ways, one way with a plugin and the other using code. If you make use of a CDN for delivering your content, you might not need to do this; some CDN providers already include query string caching as part of their service.

Do check with your provider and with your host before you do any of the following, to see if they already do it for you or can help you do it.

Using a Plugin

Using a plugin is by far the easiest way to remove query strings and the best is called Query Strings Remover. It is an incredibly popular plugin and it will take out all query strings, including “&” and “?” from your URLs in any of your CSS, JS and other static resources.

Download it from WordPress, the same way as you do any other plugin, install it and away you go. You don’t even need to configure it. DO clear your cache after you have installed it though, to make sure you can see the changes.

Alternatively, you could use another popular WordPress plugin called Remove Query Strings from Static Resources, which works the same way as the previous one. Do make sure you only run one of these plugins at a time.

Using Code

Not everyone wants to add another plugin to their WordPress website; after all, too many of these don’t do your website performance any favors either.

In that case, if you are happy and experienced enough to change the functions.PHP file for your WordPress theme then you can do it with code.

A word of warning here; do not attempt this if you have never done this before or are not comfortable; doing it wrong could break your website!

Locate the fucntions.PHP file in your WordPress theme and add this code:

‘function _remove_script_version( $src ){
$parts = explode( ‘?’, $src );
return $parts[0];
add_filter( ‘script_loader_src’, ‘_remove_script_version’, 15, 1 );
add_filter( ‘style_loader_src’, ‘_remove_script_version’, 15, 1 );’

If you do it right and you don’t break your website, you won’t get that warning in Pingdom or GTMetrix and your website should be that little bit faster.

Speed Up WordPress by updating your PHP Version



Optimizing PHP

Every website runs on code; once it used to be only HTML, now it’s a mixture of HTML, CSS, and JavaScript. But that is only when the website is loaded.

Before that, on the server, there is another, different programming language, particularly on WordPress sites, and it’s called PHP.

PHP is responsible for pretty much everything you on the front and back-ends of your WordPress site – in themes, plugins, files, so much that, without it, your WordPress site simply wouldn’t exist.

Because PHP is so important, it is critical to the performance and speed of your website that you keep PHP updated and always have the most current version running.

Because PHP is a server-side language, it is down to you to fix any PHP issues that arise – your website visitors may be using the fastest computers in the world but if your server is running out of resources it’s going to slow everything down.

Why You Need to Update PHP

As well as being a critical part of WordPress, it is also a central point of your website performance. In short, PHP is the man in the middle who gets the right data from your site, cocoons it in CSS and HTML and then delivers it to the browser of your visitor.

If the middleman slows down, so does everything else.

It is for that reason that PHP is always undergoing improvement and, right now, we are on version 7.1. Like any update, each new one brings security fixes and new features.

As it progresses, PHP gets faster, more secure, and uses fewer resources. PHP 7 has been shown in benchmark tests to be more than twice as fast as the previous version and that can only be a good thing for your website. Your server can deliver your content quicker, without having so much work to do and it is far better at error handling.

Check Your Version

Checking your PHP version is simple:

  1. Go to your WordPress hosting account and look for the PHP menus – it will be on the backend.
  2. It will be called something like PHP Version Manager or PHP Settings and here you can see what version you are running
  3. Depending on which host you are using, you may also be able to upgrade it from here but don’t do that just yet.

Upgrading Safely

It isn’t always straightforward to upgrade to PHP 7. This is mostly down to the fact that you may have code somewhere on your site that isn’t fully compatible with PHP 7 and this, in turn, means that your site may not function correctly afterward.

The following shows you how to update a live site, but you could create a copy first and try it on that, so you are prepared for anything that might happen:

Back Up and Update

Basically, upgrade your website. Back everything up and then upgrade through WordPress. Then back it up again.

Check Compatibility Using a Plugin

Even though you updated everything, there is still no guarantee that there won’t be an issue. Install WPEngine plugin, the way you do any WordPress plugin and then, when you activate it you will see a new Tools menu option – PHP Compatibility.

Choose which PHP version you want and then choose to run a scan on everything or on active themes and plugins. When the scan is finished you will see a list of warnings and errors.

Go through the list and replace or remove any themes or plugins that are not compatible with PHP 7 – where possible, just update. The plugin itself may also give you a few suggestions.

Upgrade PHP

Once you have done all this, its time to upgrade PHP. You can do this in several ways but by far the easiest is through your hosting provider’s dashboard. Like I said earlier, when you check the version of PHP you have, you may also be given an option to upgrade it as well.

Now’s the time to do it.

Check Your Website

The next step, once the upgrade is done, is to check that your website is still working as it should be. Load it up and check every element on every page to make sure it all works, and nothing has been disabled. Test your plugins and test your theme as well.

If everything works OK, then you have successfully upgraded to PHP 7.
