In this article, we will discuss some of the most common WordPress mistakes and provide step-by-step instructions on how to avoid them.


Not Keeping WordPress and Plugins Updated

These plugins will automatically reduce the file size of your images without compromising on quality. Additionally, you can also compress images before uploading them to your website using tools like TinyPNG or

Not Using a Caching Plugin

It’s essential to have a recent backup of your website, in case anything goes wrong with your website, you can easily restore it.

Not Using Security Plugins

Keeping your site secure is crucial to protect your data and your users’ data.

To customize your 404 error page, you can use a plugin like Smart Custom 404 error page or create a custom template in your theme. Customizing your 404 error page can help to improve the user experience by providing a helpful message and links to other pages on your site.

Keeping unused plugins and themes on your site can slow down your site and make it more vulnerable to security threats. To remove unused plugins and themes, go to Plugins and Themes, and deactivate and delete any that you’re not using. Additionally, it’s important to remove any outdated or abandoned plugins and themes that are no longer supported and may contain security vulnerabilities.
