I can´t tell you how many sites I have been to where it was so ridiculously hard to find what I was looking for. Every web developer should follow this brilliant advice that is given:
"Put the answer to that need right out in front where they can can´t help but say, "Hey. this is exactly what I was looking for!""

Increasing sales becomes very easy for almost any business; once they realize how important it is to become the customer.
