Not only do we try to keep our designs clean and simple without too many images, we also try to minimise the number of words. If something can be revised to make it cleaner and simpler, we will always do it. A lack of superfluous words means your readers don't get bored and will stick around longer.

Web minimalism and simplicity means emphasizing what is essential and important to your readers. Remove every non-essential or unimportant element. Readers only have so much attention to give, if you present them with less they will have more attention to give to each element.
