First thing is to go to your account at https://www.facebook.com/login/ then click www.facebook.com/pages/create Create a Facebook Page to build a closer relationship with your audience and customers.
Click to choose your page category, eg if you are a not for profit you would choose cause or community.
When you have chosen the page fill in the information required as well as clicking the drop down category so you can be very specific.
After you have followed the prompts you will then have created a page which will look like the image below. Next is to follow the prompts upload images, do some posts and then being to ask people to like it. I recommend you have done several posts and added several images onto the page before asking others to like.
When posting images and articles think about what your audience would like to see, how it will benefit them and make them smile. There is much to learn on creating an avatar of your readers, best time to post, number of times to post in a day which will be covered in another post.
