Why is it important to be Mobile Friendly?

global mobile traffic


The percentage of global mobile traffic has increased drastically over the decade. This is a key indicator for organizations to consider mobile friendly apps and websites.

In the United Kingdom, smartphones has over-countered traditional desktops or PCs as the popular means to access the internet. Tech giants like Apple and Samsung have used their smartphone hardware as a platform to push the usage of their mobile browsers. Devices come with a default internet browser, and consumers using the device become comfortable with the platform and refuse to switch. 

These two statistics clearly show the significance of having mobile-friendly apps in today’s generation. Given this significant mobile usage, developers and designers should focus on delivering seamless website UI/ UX on mobile gadgets. People won’t miss a chance to leave a bad review, be it a poor user interface or crashing, faster connection speeds, and lower latency and performance problems. 

Hence, it’s high time to design your application in a mobile friendly way and help your brand stand out by opting for mobile app testing. Testing mobile applications could unexpectedly help verify whether the mobile applications meet the expected business and technical requirements.

The first impression is extremely crucial for the success of any business or mobile app; therefore, developing excellent apps for mobile devices has become increasingly vital for organizations. If mobile apps aren’t scrupulously tested, there is a high time users encounter critical bugs on their mobile device that may lead to a poor user experience, chiefly for new users. In fact, any unexpected functionality bug or app crash can lead to immediate uninstallation of that application. This also results in the loss of esteemed clients and revenue. App crashing, freezing, and slow responsiveness is the prime bugbears when it comes to application issues.

While this explains why one should perform mobile app testing. There are still a huge number of people who access web apps on mobile browsers. This could be due to a lot of reasons, such as privacy concerns, storage space, etc. One major issue that users face when accessing a web app on a mobile browser is responsiveness. Most often than not, companies ignore making the app responsive for a mobile browser.

How to be Mobile Friendly?

Now that you have understood the importance of being mobile friendly, let us look at the different options. You can either create a native app that can be downloaded from the App Store or Play Store or make your web apps compatible with different mobile browsers. It is recommended that you do both to ensure that you reach a larger audience. No matter which path you choose, it is critical that you test them. Listed below are a few best practices that one must follow when it comes to mobile app and mobile browser testing.

  • Screen size and Resolution

Mobile devices generally come in predefined screen sizes. It is considered a primary step in mobile web app testing as it is a major concern for testers. This helps the app manufacturers create a reference end for their next purchase. The next step is to test the resolution of the mobile device. The better resolution a gadget has, the more refined its screen is and, eventually, a better experience for the user. As a tester, you should always do your research on the screen size and resolutions that you must test on before you start the test.

  • Focus on Optimizing Web App Speed

Speed is the greatest factor in any website. The standard website load time for any mobile website is 1-2 seconds. As per the statistics53% of mobile site visits are abandoned if web pages take more than 3 seconds to load. Besides, slow load times are the prime reason visitors abandon a checkout procedure.  In short, your website must load as quickly as possible!

  • Clean Web Design

Web developers should ensure they aren’t cluttering the site by providing all functionality on similar page. This creates confusion, making it hard for visitors to navigate a web page with various elements. For flawless user experience, prioritize an orderly, clean, minimalist design that makes navigation intuitive. Offer only the crucial functions upfront as those are the ones users will actively seek. 

What’s the solution? Developers can incorporate the core elements of modern web design – the Hamburger button on any site. Mobile phone users can easily open the complete menu with a single click if executed. This makes navigation simpler and fosters a heavy visual appeal.

Additional-Tip: Once complete, consider implementing again to make your website appealing and mobile friendly. 

  • Easy-to-use Navigation Interface

One of the top mobile friendly app tips comprises developing a simple navigation interface. Whenever visitors land on your app, a user should understand your app, take desired actions, and end up with an easy buying process without being distracted anywhere.  In mobile app development, a popular model, i.e., the Keep it simple stupid (KISS) model, is used to better build an app with a user-friendly interface, easy navigation features, and least tasks. It also requires a focus on themes, backgrounds, and colors that need to be smoother for a smooth end-user experience.  

  • Web Browsers

The most time-consuming section is to test on web browsers. Unlike OS (operating system) versions, browser versions are launched very often, with an average cycle of 4 weeks. Besides, there doesn’t exist a couple of browsers in the marketplace. Even though you take out Chrome which has more than 60 percent of the market share, other browsers also hold a substantial market under their reach.

Regarding market share, web browser fragmentation is highly concerning than the OS. With a 63 percent share in the market, the image shows how chrome’s version competes with the visitors.


With every browser version, you can expect fresh features to be introduced and a few deprecated. This portion is similar to Operating systems. Testers need to be careful about testing the mobile web application in these browsers. The key thing we are searching for here is property support removal. For instance, a CSS function filter () is supported only in the Firefox web browser. If the software developers have kept Firefox as their prime browser for app development, you may expect a few surprises whilst testing.

With a mobile-first app design approach taking priority, it is vital to craft and updates your website’s mobile content with a pinpointed approach. Developers should consider the space restrictions on small screens to make sure only critical content components are notably displayed. Developers can evade this by opting for a visual comparison test that will mitigate any sort of web design error to show up in production.
