1. Hosting Service

Shared hosting provides unlimited bandwidth, space, emails, domains, and more. However, it fails to deliver fast-loading speed and results in unmanaged traffic on your website. It is so as you share resources with many devices in shared hosting.

10. Update Your WordPress Site Regularly

Update WordPress Site

Over the years, WordPress has gained massive popularity. One of the primary reasons behind that is its regular update feature.

Not only does a WordPress update fix security issues and bugs, but it also provides additional advanced features to cope up with the emerging web technologies. WordPress regularly updates your theme and plugins.

Suppose you don’t update your site regularly, your website loading speed increases. Your website also becomes more vulnerable to security threats. So, if you want to make your website perform as fast as it can, always keep your WordPress site updated.

11. Lazy loading

If you are running a blog site, you can benefit using the lazy loading feature. Lazy loading is a feature that loads only the content visible on the screen. As you scroll down, your website loads automatically.

For a content-rich website with plenty of images, videos, and comments, lazy loading is an effective way of maintaining speed and enhancing user experience. There are several plugins that you can use for lazy loading. 

12. Do not Upload Media Files Directly to WordPress

Though WordPress allows you to upload video and audio files directly on your website, doing so can make your website slow. It costs you a lot of bandwidth and increases the backup size tremendously.

By default, WordPress displays images and video content in an HTML5 player. However, it is best to embed files from YouTube, Vimeo, SoundCloud, and more as it makes your website fast and reduces the backup size.

13. Minimize HTTP Requests and External Links 

A typical WordPress site includes files, scripts, stylesheets, images, and other files from external sources like Google, Facebook, and such. Together, these components work to provide advanced and powerful features.

These components generate HTTP requests when used. When there’s excess HTTP requests, and scripts on your website, a big chunk of data is added, and your website becomes slower. So, if your website is overpopulated with external scripts and other resources, you might want to keep it to a minimum.

You can either disable external scripts or merge them into a single file. It is best to use only a few scripts, including essential ones like a commenting system or tracking tools, like Google Analytics.

14. Use Optimal WordPress Settings.

Within your WordPress website settings, you can make a few changes to speed up your WordPress site. Although they may look like minor changes, they can make a difference in your loading time. 

Firstly, do not forget to change the default WordPress login URL. This can protect you from the security threats from bots and hackers and decrease the bandwidth used by bots that repeatedly hit this URL. You can change the login URL manually or use plugins for ease.

Secondly, disable themes or plugins update. When you enable updates, the built-in update checker checks for updates by making an external GET request. Frequent requests can overload the server. 

These changes can positively impact the loading time of your website and bring noticeable improvements. 

15. Check for Pingback and Trackback.

Pingbacks and trackbacks alert you when your blog or page receives a link. It is a significant feature as it allows you to check the links of your website. However, other tools, like Google Webmaster Tools, can help you do the same. 

One of the major setbacks about pingbacks and trackbacks is that it puts an undesirable amount of stress on the server resources. Whenever someone tries to link up with your website, your website generates WordPress requests back and forth. This can cause a decline in the loading speed of your website. 

So, to turn it all off, Go to WP-Admin, then Settings, then Discussion. Unselect “Allow link notifications from other blogs(pingbacks and trackbacks)”. That’s it.
