... If (possible) consumers decide to give you their attention, you only have a second to keep it. It's essential to create attractive graphic materials in order to consistently get your message in front of your target. It's even more imperative to develop designs that stop trespassers in their tracks, engage them and lead to a purchase action. If your graphics don't get people's attention and action over time, all that money you spent on advertising, printed materials, website design, etc. in the first place is wasted if readers continually whiz past your advertisement and turn the page or leave your website before visiting any of your pages.
