Although we recommend responsive design to all businesses that practice digital marketing in some capacity, we'd never suggest anyone to release a responsive site without testing it. Unfortunately, that happens way too often.
When organizations don't test their responsive websites, they don't know if they'll function right on all devices. The main feature of responsive design is that it can adapt to any screen size, but you have to test your website on multiple devices to know it's working right.
A recent Practical Ecommerce article talks about common mistakes businesses make concerning responsive design. According to the article, many small businesses skip testing because they don't have the resources:
"Testing is mandatory before making the responsive sites public. But responsive sites are often released with minimal or no testing. I’ve seen the primary flow for responsive checkout to be broken, for example — testing could have caught that. Most retailers have limited resources and hence once the responsive site is built, they want to take it live as soon as possible without thoroughly testing it."
It's not hard to see what's going on here. Small businesses only have relatively small budgets for digital marketing, and web design is just one component of their marketing strategy. Since they've already invested in responsive design, they don't want to spend any more time or money on their website.
But here's the thing: testing a responsive website is the easy part. All you have to do is access it from various devices and see how it functions. If it runs smoothly, then your job is over. And if it doesn't, then there are a few elements that you need to fix. At this point, it's better to go the extra mile to improve your user-experience rather than leaving your website the way it is.
