There are two types of areas on Facebook to get familiar with. These are the personal page and the fan page. Here is how both work.
A personal page is the thing you log into. The thing associated with a username and password. Each human can have one and only one personal page. That page must be set up with that person's real, legal name. These are the Facebook rules which are carved in stone and which Facebook actively enforces. Some authors have set up personal pages in their "pen name" name and garnered thousands of "friends" - only to lose them all when Facebook discovered what was going on. Just don't risk it. It's not worth it. Have one account you log into. This should be your personal name. You never have to show this publicly to anybody! This account is solely for administering your other Facebook tasks.
You can choose to never post on a personal page if you wish. It can be wholly private and never seen by anybody. You can also of course choose to have it public and start connecting with "friends." But this personal page generally shouldn't be your main author area.
Because when someone "friends" you both of you can see each other's posts. You might not care because you're only using this area for author posts - but the fan on the other end might not want to "friend" you because they don't want YOU seeing all their personal posts! Many people take their privacy quite seriously.
Also, your Facebook personal page can only have 5000 friends. That's it. That might seem like a lot - but for an author that is hopefully only the start of your upward progress. Do you really want to limit your fan base growth? Do you want new fans to be blocked because you're full?
So it's best to use your personal page for personal things. Alternatively, you can leave your personal page entirely blank. That's fine too. The key here, as an author, is to then make that fan page. That's where you'll be connecting with fans.
A fan page is different from a personal page because fans do not have to FRIEND you there. They don't have to reveal all of their personal details to the author. All they do is "like" the page. The page's posts still can show up in the reader's timeline. The fan can still make comments on posts and "like" them and so on. But there's a level of privacy that's maintained. The author can't see all of the fan's personal posts. And for most fans that's quite important.
To create your own author fan page, go to any other fan page and click the "Create page" button in the top right. So, for example, go to:
Lisa Shea Author Fan Page
Click on the CREATE PAGE button in the top right. Follow the instructions to create your own fan page. I definitely recommend you call it FIRSTNAME LASTNAME Author just as in mine. You want your name to be the first thing they see.
Once you get that fan page built, tell all your friends and family! Ask them to like it and share the news. Then start posting it to book promotion groups to encourage other people to come see what it's about.
Look at other author pages in your genre to see how they post there. It's good to aim for daily and to post news about your writing, your book, or anything on topic. Avoid making it a sell-sell-sell place. People tune out those pages. Make it useful and informative on your topic, and make it personal. Respond to posts and questions. The more you engage with your fans, the more they'll share the news when you've got something fun to announce!
