The organization you belong to will typically rank very high on search engines which bring a lot of visitors to the LOCAL membership directory.
In order to take advantage of this online visitor traffic it's very important that you "Optimize / Setup" your online advertising system. When completed your business will show for more search results and become easier for people to find you.
If you already have a website then count on this to will help guide more people your way by catching traffic from the membership directory. When you setup your system it's then indexed on the directory. Once this is done people can search by key word(s) for the services they need and find you... once there, they can easily navigate to your main website. For members without a website - you will be provided with one.
