Which Browsers Are Important For Your Cross Browser Testing?

Did you know?

Every website on the internet communicates in a unique manner with every browser. A browser interprets web elements in a separate manner as compared to other browser and renders the website accordingly. This means the look and feel of a website are not only dependent on the front-end development team but also on the browsers being used to access the website.

The practice to ensure the avoidance of browser difference is termed as Cross Browser Testing, also known as Browser Compatibility Testing.

Making sure that your website delivers a consistent user experience to every visitor is imperative for big enterprises and startups alike. A little carelessness from your testing team may end up leaving your customer’s with a red-faced moment. It is precisely why one cannot afford to miss out on performing cross browser testing. However, performing browser compatibility testing is easier said than done.

Think about how many browsers your visitors may have used to access the internet. If asked by your manager or the board members, would you be able to confirm the most important browsers which are fully responsible for bringing you every last dime of your web traffic? or the majority of it? If you are receiving traffic from 50 browsers, would it be okay to neglect the remaining of hundreds of browser versions?

The number of browsers used by your customers may vary from hundreds to thousands, depending upon which browser version they are using, which device they are using it from? Are you getting majority traffic from mobile browsers or desktop ones? Are you targeting the right browser with respect to geographic locations of your targeted audience?

You may or may not have the answers to these questions now but don’t worry! By the end of this article, you will be having critical statistics for defining & refining your cross browser testing strategy in 2019.

Let’s Begin!

Google Chrome has been the most used web browser worldwide from a while now but that doesn’t mean you can turn a blind eye towards its competitors Mozilla Firefox, and Safari is equally trending across different devices. Opera is the second most important browser in Africa and UC browser in Asia. Researching and analyzing market shares of various important web browsers and web browser versions, geographically and cross platform, can help to strategize cross browser testing of an application.

Market Share of Web Browsers Worldwide

According to the data fetched from Statcounter, we can interpret that, in the past 12 months Google Chrome, undoubtedly has the highest market share with approximately 60% worldwide. Followed by Safari with approximately 15% Firefox with 6%, and so on. So it’s only natural to develop your website in a manner that they are compatible across these web browsers, as they are the trending ones. Also, make sure you test on Safari and other browsers. However, this data is still too vague and it is necessary to delve deeper by filtering out a few details that would help to prioritize and strategize cross browser testing process for your websites or web-app.

To illustrate my point, I’d like you to take a look at below two stats:

Important Browser Versions Observation

According to the very first graph, we could conclude that the 5 most important browsers for the past year were Google Chrome, UC Browser, Firefox, Safari, and IE. Now, if you take a look at the above graph you will find that Firefox and UC Browser are totally out of the picture. Also, we know Market Share for Chrome and Safari in the past 12 months are 59.82% and 14.57% respectively, out of which, 29.64% market share is for Chrome Android and 9.63% for Safari iPhone, as shown in the above figure.

Moreover, IE 11.0 also has a fair share and could be prioritized for web based browser testing. Last year browser version Chrome 69.0 was rolled out with the newest design and many bug fixes, but even if it has been one major upgrade; Chrome 71 and Chrome 67 have highest market shares in Desktop browser versions.

Browsers Other Than Chrome

The above graph indicates monthly trends of important browser market shares for the past year. If we closely analyze the graph for the past 12 months, we can also see, there has been a rapid hike in the market share of Samsung Internet in the last 6 months, along with the fall of UC Browser.

Targeting Second Most Important Browsers On The Basis Of Different Continents

We know it by now, that Chrome is the most preferable browser option for a majority of internet users. But which is the next one? Knowing the second most preferred option is pivotal for targeting a global audience towards your website or web-app. And the competition for the second spot varies differently across different continents. Let’s analyze the second most important browsers on the basis of different continents.

It is imperative to keep a track on sources responsible for bringing you with the majority of your web traffic. Here are some web analytic tools to help you understand your users better.

Asia

After Chrome, UC Browser is the most important browser in the continent of Asia. Also, It can be concluded that Safari has also taken a hike in the first quarter of 2019. So, both the browsers are matching each other neck to neck in the race for the second spot within Asia.

Africa

When it comes to Africa, then Opera is dominating in the second position, after Google Chrome of course.

Europe

In Europe, Safari is considered the second-best option, after Google Chrome. Although, Mozilla Firefox has also got a considerable fair share in the market of Europe. So the 3 most important browsers for Europe market would Google Chrome, Safari, Firefox.

North America

Similar to Europe the spot for first and second most important browser go to Google Chrome & Safari respectively. The spot for 3rd place is evenly matched between Mozilla Firefox & IE (Internet Explorer).

South America

Chrome has dominated this continent in unequivocally. Far from the number 1 position, Safari is being the second most choice, but only just, as Mozilla Firefox is considerably close as the third preference.

Australia

Just like North America, Safari outruns other browsers for number 2 spot.

Antarctica

Not one of the continents that most of us would be concerned about considering the population on it. However, according to Wikipedia, about 5,000 people reside in the science stations temporarily, throughout a year.

Interestingly, Mozilla Firefox is considerably near to being the first most preference in Antarctica’s market share.

Targeting Most Important Browsers On The Basis Of Different Devices

Now that we are aware of which browsers to target for different continents. We now will look into the most important browsers based on the devices being used.

Desktops

Chrome stands tall again. Unexpected to many of us, IE and Mozilla Firefox are evenly matched. Now, we know that IE has been considered an old goat, and you would probably also know that Microsoft won’t be offering any support for new web standards in IE any longer. After such an announcement from Microsoft, we can expect the market share for IE to drop down drastically in the coming times.

Mobiles

A majority of users prefer Google Chrome to surf the internet through mobile devices. Surprisingly to many of us, Mozilla Firefox has a hardly noticeable market share. Safari and UC browsers are holding the second and third favorable spot respectively.

Tablets

Safari beats Chrome. As seen from the chart below, it can be concluded that more than half of the browser market share lies with Safari in case of tablets. I believe, the primary reason for that lies with the dominance of iPads from Apple.

2000+ Browsers AND OS

Considering Android

When we look into the market share of Android browsers then we can notice a very dramatic shift between Chrome and Safari in recent months.

Peculiarities

There are also a few browsers that although, are not globally renowned but are most important browsers after Google Chrome in some countries. I will be talking about two such peculiarities.

Russia and Yandex

If you are targeting users from Europe & Asia then Russia comes as a major consideration for many enterprises. An interesting thing to notice in Russia is that after Google Chrome the second most important browser is Yandex. You may or may not have heard of it. The statistics of Yandex are not noticeable on a global scale. However, if you are targeting Russia, then it is one browser that you should not miss out on.
