Inclination towards UI & UX
The primary reason why Apple products are loved by users worldwide is because of their UI and UX. Users love the touch and feel of an iPhone and the way it responds to their actions.
When a user enjoys a wonderful experience on your website, they will not only use it often but also recommend it to others. If you are selling the best in class service or product with a bad UI/UX then the probability of conversion is low.
The website with a Good UI/UX decides the outcome of the sale. This is why UI/UX design is important.
