Tips on How to Boost WordPress Website Speed & Performance

Disappointed with the speed test result of your website? Nothing to worry about, you can always do WordPress page speed optimization to get it up to score your desired performance result.

But how to improve WordPress site speed? Here are the 11 best ways you can speed up your WordPress website:

1. より高速なサーバーを選択します。

By faster server, I mean preferably a dedicated server. In the beginning, it’s very common for people to go for shared hosting as it is cheap. However, with time, once you get popular and get a good amount of traffic to your website, it’s always a better idea to move to dedicated hosting.

Since shared hosting and all the resources are being shared among multiple websites, it has an unavoidable bad effect on your website’s performance. Especially, most shared web hosting fail to provide 99 percent uptime, and in the peak hours website loading speed is not satisfactory.

So I would suggest that if you can afford it, you should switch to a dedicated server for your WordPress hosting that receives a good amount of traffic on a monthly basis.

注記： Also, make sure to choose a server that is located close to the location from where your receive the largest number of website visitors. The location of your server also plays a significant role in your website’s speed because of various factors such as Network Latency, TTFB(time to the first byte), etc.

2. キャッシュプラグインを活用する

The caching plugin makes a website fast by skipping many steps while loading a webpage. It does so by making a copy of the page after the first time a page is generated and then uses that copy to serve every subsequent user that visits your WordPress site. 

Since WordPress CMS is dynamic, if you do not use a caching plugin, every time someone tries to access your website, it will repeat all the processes and fetch all the data from your WordPress database, which will put a great deal of load on your server and hence make the site super slow.

So, use the caching plugin on your website to boost WordPress speed. You can also combine advanced caching mechanisms like Varnish with a caching plugin to see a remarkable improvement in your website’s loading speed.

3. Minify HTML, CSS, and JavaScript

While you need HTML, CSS, and JavaScript to build and run your WordPress site, if not optimized, it can make your website somewhat laggy.  And that is the reason, experts recommend always minifying your HTML, CSS, and JavaScript codes. 

Minifying code does not affect how your website functions; it only removes unused code and replaces variable and function names with shorter names. As a result, it reduces load times and bandwidth usage on your websites. So, if your website is currently not using minified code, then minify the code fast to improve WordPress website speed and performance.

4. Remove Render-Blocking JavaScript and CSS

Remove Render Blocking JavaScript and CSS, as the name suggests, blocks your webpage from loading before these scripts are loaded. This is one area of improvement that Google Pagespeed Insights frequently suggests to improve.

Most of the JavaScript is used to add animation or a pop-up on a website, which is not really needed until the site fully loads. These can result in lazy loading for your website. You can remove these render-blocking codes to load later so they have no effect on your website’s actual loading speed. This is an effective way to improve WordPress site speed.

5. Choose a Lightweight and Fast Theme

A website is a visual form of marketing your product and service, and it’s only natural to be tempted to go for a plugin that has too many animations and functions. However, too much animation and additional function if makes your site slow, so it is really of no use.

I am not saying go for a bland website, but make sure loading speed is on your checklist when you choose your WordPress theme. You need to find the right balance between the functionality and animation you want in your website and the loading speed.

6. WordPress Web サイトの画像、メディア、データベースを最適化する

With time, your website turns into a storehouse of unused images and media that can increase your website size and thus affect the site’s loading speed. The same goes for databases as well. If not optimized, a database stores unnecessary information, which results in bad WordPress site speed.

So, do check if your website is filled with redundant images and media files or not. And if so, do clean them up. Also, it’s always a good idea to optimize your images before uploading. A reduced media size, like an optimized image and database size, will reduce your website speed as well.

👉👉 Both Image optimization and database optimization should be a mandatory task for website maintenance as well. To learn more helpful tips, read our blog on WordPressウェブサイトのメンテナンス.

7. CDN(コンテンツ配信ネットワーク)を利用する

While it’s a good idea to get a Server located near your frequent visitors’ location. This is not enough to cater to all the people who come to your site. And CDN solves that issue for you.

Content Delivery Network (CDN)  keeps a copy of the website in different datacenters located in different parts of the world. This way, you can be assured your website loads at a certain speed, irrespective of the location someone tries to access your site.

8. ピンバックとトラックバックを無効にする

Pingbacks and Trackbacks are great to find out when one of your blogs or web pages receives a link. While these are great, you need to know that these links can put an unwanted strain on your server. 

Besides, if you turn these two features on, you are always at risk of getting DDoS attacks. So, for WordPress page speed optimization and securing your site from DDoS attacks, make sure to disable pingbacks and trackbacks. You can disable these easily from the WordPress admin dashboard.

If you are not currently using plugins or themes, then it’s absolutely unnecessary to keep those files on your server. The bigger the size of your website, the slower it is likely to load. So, uninstall any WordPress plugins and WordPress themes you don’t use.

Along with uninstalling, you also need to keep an eye if your themes and plugins have updates available or not. If so, then make sure you update them.

However, don’t just start using the latest version of PHP because your WordPress theme and other plugins also need to be compatible with the version of PHP you use on your site. So, first, check if themes and plugins are compatible with the latest version of PHP, and then upgrade to that one. 

11. Reduce the number of post-revisions

I know, you probably didn’t think you would find this option in the ” tips on how to improve WordPress site speed” list. A number of post revisions can affect your website’s speed. Each time you save a draft, WordPress saves it indefinitely. These additional versions saved on your website can slow your site down.
