My slow learning curve to create my blog with WordPress, although exciting, was intimidating at the beginning. I looked down on myself, thinking I had no IT skills. Now, I can say that it's not that difficult to build a beautiful WordPress blog or website, even if you are a complete beginner.

One of the questions I searched for answers was about how to delete unused WordPress themes installed on your blog.

You may have installed a few themes as you start out. Along the way, you found another beautiful theme and decided to try that out. I did that. Eventually, I had more than 7 WordPress themes installed. This was in addition to WordPress' own basic theme.

Why You Should Delete Your Unused WordPress Themes

The main reason why you should delete unused WordPress themes installed on your blog is that they can slow down your site. Themes take disk space and increase the size of your backup file.

According to Google, most sites lose their visitors by half while loading. To retain visitors, your site must load faster even on mobile devices. You can test your site's speed with Google's Test My Site tool and receive recommendations for improving website performance across all devices.

Research has shown that more than 52% of internet users now access the internet using a tablet or mobile device than a desktop computer. Your website or blog's mobile compatibility is important not only because of traffic but also because Google loves mobile-friendly websites to deliver information to its users.

The second reason is that you need to update the themes regularly when the theme developers provide an update. If the developer does not update themes or if you don't update it, your blog becomes vulnerable to security breaches.


How to Delete Installed WordPress Themes

Now that you know the importance of not having too many themes on your blog, let's get to the instructions on how to delete the unused ones.

  1. Log into your WordPress Dashboard.
  2. Go to Appearances, and you'll find Themes.
  3. Clicking on Themes will bring up all the themes you have installed on your blog. Find the theme that you want to uninstall or delete.
  4. Hover your mouse over the theme and you'll see Theme Details appear in the center of the installed theme. Click Theme Details.
  5. This will display information about the theme. In the bottom corner, in red, you'll find Delete. Click Delete.
  6. Confirm if you really want to delete the theme. Once you do so, the theme will be permanently deleted from your WordPress site.

Take Note

1. Keep the theme you are currently using and always have a backup theme.

2. Always keep the newest WordPress theme around to assist with any troubleshooting.

3. Always have a backup of your content when changing themes.

What About a WordPress Theme That You Installed as a Plugin?

I came across a premium theme that you can install as a plugin. To delete such a theme, go to Dashboard, Plugins and find the installed plugin. Click Deactivate for the particular plugin and then Delete. That will remove the plugin.

How Many Plugins Is Too Many for WordPress?

It depends on your goals. For me, over 5 plugins are too many. Regarding site speed, limiting the number of plugins should be a goal of a website owner. As explained above, you lose visitors when your site does not load fast.

Too many plugins can cause slower page load times. Users will leave your site and not come back. The general rule is to keep your plugins below 5 to maximize the health of your site.


What Is Google's Optimal Loading Time Standard?

Test your site speed using Google's Test My Site tool. The optimal performance is 1 to 5 seconds. That means, if your site takes less than 5 seconds to load on mobile devices, it is excellent.

Removing unused installed WordPress themes from your blog and reducing the number of plugins on your site to 5 or less can greatly improve your site's performance.

Traffic is key because your potential to earn revenue from your site increases when you have more visitors.

Optimizing Keywords for a Higher Google Ranking

Since I mentioned traffic, let me elaborate further that while site speed is important in keeping viewers engaged, and not losing them, optimizing keywords gets you higher on page one (1) of Google.

Higher search ranking is important because most people visit the results that appear on the first page. More people will visit your site if you are on page 1 under the specific keyword they are searching.

In this article, I have provided tips on how to find keywords for an article that gets you a higher Google ranking.
