People do business with other people, and visitors want to learn a bit more about who the people are behind the company. The about page is often one of the most visited pages on any website. This page should give a brief summary of who you are, your company history and what isolates you from the competition.
What to include:
A summary of your company, whom it employs (with biographies and pictures of the staff, or just yourself if you are a sole proprietor), any special achievements you received, and the ways you differ from others that provide the same product or service.
