I've taken these quotes directly from the website critique and author Vincent Flanders.
Do go there, and read the whole thing. Entertaining and insightful.
Here, according to Flanders is Mistake #1. And I agree with him.
Believing people care about you and your web site.
Write these two sentences where you can see them as you’re working on your computer:
1. The only reason my web site exists is to solve my customers’ problems.
2. What problems does the page I’m looking at solve?
Nobody cares about you or your site.
Really. What visitors care about is solving their problems. Now. Most people visit a web site to solve one or more of these four problems:
1. They want/need information
2. They want/need to make a purchase / donation.
3. They want/need to be entertained.
4. They want/need to be part of a community.
Too many organizations believe that a web site is about opening a new marketing channel or getting donations or to promote a brand or to increase company sales by 15%.
No. It’s about solving your customers’ problems. Have I said that phrase enough?
