There are so many browsers available, which are viewed on all types of devices and on various screen sizes. It is, therefore, essential that you perform testing on how the user will experience your site in each of these environments. Each browser handles the information it processes from the server in its own unique way. Testing your site on one browser is not enough; you need to view the user experience across several different browsers, devices, and screen sizes. Cross Browser testing involves testing both the client side and server-side behavior of your site, when it is accessed using different browsers. Through this testing you will ensure that your site displays properly regardless of which browser is used.
Cross browser and compatibility testing should be part of the initial site development and be a step that is revisited periodically. Browsers will change as new versions are implemented, so continuous testing is critical to making sure the user’s experience is flawless.
Increase SEO rating
Google is continuously updating their SEO (search engine optimization) algorithm. A site’s ranking will increase if the site is more responsive and cross-browser compatible. An improved site ranking ensures you are being seen by your audience.
Testing my site
I used Browserling to test my site on Explorer, Google Chrome and Firefox. I also tested it on tablet and mobile sizing. I found all three browsers loaded my site correctly. When it was brought down to tablet and mobile size, the site adjusted layout and content appropriately, resulting in similar user experience.
