When you want to share your information with others all you do is either give your business card, give brochures or explain them in person or on phone. Business cards and brochures have text limitation where you cannot explain everything about you. In person meeting and phone calls consumes your time every time you explain about you to others. This is where your website comes into picture. You can update all your information in your website ( your qualifications, expertise, services offered by you, contact information, pictures, videos, etc) and you shall just share your website link to others through business cards, brochures, emails or by word of mouth (even with a single SMS). After the initial meet, they shall get into your website at the time of their convenience and know more about you. When they know more about you, they would trust you more and which in turn will help you both build a better rapport and it may turn into business relationship as well.
