Choose a big bandwidth and data transfer

 The Bandwidth or the Data Transfer ( also called Traffic ) , is a very very important item to select. While your site is growing and has a large number of visitors and they open pages , leave comments, download files .. etc,
these movements are called the Traffic or Bandwidth, so you have to choose a big one for the future.
Almost of hosting services will provide you an UNLIMITED bandwidth, you must make sure of that yourself.
