While researching web design, I stumbled upon a website that talks about a visitors first impression on your website. I think that this is a very important attribute to consider while designing your site. Things such as load time, making sure the material is user friendly etc. I think any good designer should know the basics of good design. It's important to keep these in mind while creating a website. There needs to be visual hierarchy, a pleasing color palette, and organized layout.

Of the above things, I think that user friendly is such an important thing to keep in mind. As designers, we're obviously going to pay attention to color, layout, etc. But we need to remember that our sites need to keep people interested and coming back.
