Website Functionality Testing Checklist

Website Functionality testing is critical before the launch of any new website. It is important to make sure the website functions correctly before you start getting visitors and traffic to your site.

Website functionality is primarily how your website works and what it can do. The last thing you want is for a button to fail and crash as the link is incorrect, or imagine someone trying to buy your product or service and the payment doesn’t work and that new customer leaves.

We all use different browsers to look at websites, and they all work totally differently so you must check your website is displaying and working on each browser.

Have you thought about how you will track your website visitors? Adding google analytics code to analysis data will give you great insight into who is visiting, from where and even more important, your top-performing pages so start gathering that information from day one. This can also be a way to get Google search console verification.

There are many things you need to test before your new website launch.
