Customer traps:

The blank website filled with nothing useful except for possibly the physical address of the business and very cliché stock photography.
Someone told you that you just needed to get on the web. They forgot to tell you the other part about websites serving specific purposes. Many brochure websites do absolutely nothing to put the client or give you enough credibility to assuage fears of buying from you.
These pages tell us (your customers) about your company. They tell us how your company operates, what its track record is, your philosophy, etc. It is a narrative for your company. This is one of the few chances you get to show your business as it is and even translate for the user what they should be thinking of your business.
The ‘About’ page should actually have something about you or the humans in your company. It should not be another page of sales pitches. If I’m looking for any information on you, chances are I want to find valuable information on you. For every customer that buys your dummy information replete with jargon, there are 5 others who will look at your competitors.
