Flow
A grid provides structure, however by itself it is not enough. The user’s eye has to be drawn around the page until it alights on the various screen elements we need them to pay attention to. In other words their eyes need to flow from one item to the next.
Creating flow can be achieved in lots of different ways. On boagworld.com I used colour, faces, illustrations and typography to make sure users were looking at the right items in the right order.
As search marketers, your job is to generate traffic. More traffic means more sales. As we become more wise to the math of conversion, we begin to realize that it may make sense to shift some attention away from the unending search for higher click-through rates and toward getting higher conversion rates on our sites.Two page analyzers we use are AttentionWizard and Feng-Gui. These services analyze a screen capture and tell you where your visitors eye is likely to fall when they first arrive. It simulates an eye-tracking study. Run your important pages through one of these and do the same with the equivalent page from your competitor’s site. You may learn that they are directing the eye more effectively.
It's often a real challenge for designers to set up a web page with all the required elements -- images, disclaimers, links -- while guiding users to make a purchase, click on a link, sign up for an e-mail newsletter, etc. For businesses that rely on the web for sales -- or “conversions,” as they are called in web sales circles -- it's a matter of dollars and cents because users aren't going to keep surfing on a site that's too difficult to understand or too confusing to look at.
