first of all you will have to make your mind very clear about "what you want to do",you will think of number of other questions floating in your mind e.g

  • what you are?
  • why do you want to create a page?
  • do you have a business plan or services to offer?
  • if u get "likes",how will they be helpful for your business?
  • do you need real audience?
  • do you need local audience or worldwide?
