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?
