When visitors come to your site, especially for the first time, they don’t care about many of the things that you care about. They don’t care about your long, distinguished history or fascinating life story. They may care about those things later, but not at first. First, they want to know what you can do for them.
Visitors show up at your site because they want to solve a problem or answer a question. If you don’t do that for them, they will click away to find someone who can. So, help them do that early and often.
Answer their questions and help them solve their problems. Then they won’t just visit your site. They’ll also give you their business.
