The best way to learn how your website works on a mobile device is to test it. The following tools can help you test your site:

1. Google’s Mobile-Friendly Test: This is a simple tool. All you need to do is enter the website URL you want to check. Then Google will generate a ‘user-friendly’ review.
2. Mobiletest.me: Enter the URL of the website you want to check, and select the device and the operating system.

From there, you can have a complete view of your website on any mobile device. A complete view allows you to fix errors before your launch. Basic problems can be solved before a poor UX is created. For example:

• Website Layout: You can ensure that icons, menus, and tables are displayed at the right viewing size for each device
• Forms and Data Entry: Avoid making users type in small text fields or press tiny buttons with their fingers
