Once you have begun planning the goals of your website and how you will execute them through design decision, it is important to remember that the site's content is what people are really there to see, so don't forget to proofread, edit, and re-edit your work. Typos and other mistakes is one of the easiest ways to make your site look unprofessional and sloppy.
good design & readability go hand-in-hand. While you choose a layout, colors, and fonts, the first question you ask yourself should be whether it is hard to read your site or if it would give someone a headache if they looked at it for too long. As a general rule, light backgrounds and dark text colors are easier to read, so if you aren't a color theory-buff, stick to that formula.
