Constant access to information and information overload causes us to quickly skim sites for info that’s desired and relevant. Stop and think for a second what your personal browsing habits are and where you fall on the impatience scale. Generally, a multitude of tabs are simultaneously open and tabs get closed abruptly if a page is slow loading or irrelevant in content.
For e-commerce sites, it’s the same and quick page loading is even more important. You’d browse products the same way as for any other info. You’d have an idea what you want or need and make some research for options. Once you’ve decided on a selection of products you are set on a goal - to gain possession of them. The final step standing between wanting and owning is completing your order.
