Cross Browser Testing Tools To Improve Conversions

Cross-browser testing tools help identify problems with the user experience

Why Cross-Browser Testing Tools?

Do you every wonder why your conversion rate is significantly lower on some browsers and devices?

This is because web pages can look very different in each browser they are viewed in because a browser understands some code slightly different than other browsers. This can often be the cause of your conversion rate being significantly lower for some of your supported browsers or devices. This is why cross browser testing tools are essential for conversion rate optimisation.

With over 1,000 combinations of browsers, operating systems and plugins it is practically impossible to check every single page to ensure it renders correctly for all users. Even if you only focus on checking the most common browsers, OS, device and plug-ins it is still a very time consuming and complex process.

When you view sites on different browsers and devices it is not uncommon to discover some of the problems shown below where text and pictures overlap or assets don’t render correctly. This is because it is very time consuming to test every little change you make on your site on all browsers and devices.

Issues cross browser testing would identify


For most organisations it is likely to be more efficient and better use of scare resource to get a company that specialises in cross browser and device testing. They can quickly check and come back to you with screen shots from multiple browsers, operating systems, devices etc. You can then concentrate on the analysis and fixing problems identified by the cross browser testing tool.
