If you ever go into the creations of advertisements, this info-graphic is a great example of what to do and not to do. When using fonts, you obviously should not write with the pen tool ever (as shown in the picture below). If you do happen to write horribly, it should only be used in an ad for babies. Another appealing attribute of a wonderful advertisement is the use of correct colors. A bright, eye popping contrast is most likely the wrong choice for text and highlight combined for an advertisement. Borders help the look especially if the images and texts are clear. It takes a certain eye to make sure an ad is professional, and all someone needs is practice to achieve the clean effect.
