It’s one thing to just put up a Facebook page – But if you want it to really take off, you’re going to have to spend some time and energy promoting your page.
Facebook makes it easy to get the word out with a wide range of tools for promoting your page. Here’s an overview of the various tools you can use to promote your page.
Let’s walk through these marketing options one by one.
ADVERTISE ON FACEBOOK (BOOST YOUR PAGE)
Advertising on Facebook allows you to create targeted advertisements to drive traffic to your Facebook page. 
Your Facebook page will be shown to thousands of people. If you targeted your ad well, a good number of them will become fans of your page. You can also advertise or boost your posts, simply by going to your admin panel and clicking on “Boost Post” next to the post you want to promote.
INVITE EMAIL CONTACTS
If you have a pre-existing email list or have been in business a while, you can leverage that goodwill using the “Invite Email Contacts” method.
There are two ways to use this method: By importing your contacts from an email client or by uploading a contact file.
Method #1 supports many formats, including mainstream email clients like Microsoft Outlook or Thunderbird. It also supports autoresponder exports like Constant Contact or Aweber.
The latter method will log into your email for you, download your address book of people who you’ve sent emails to and import it into Facebook.
Once Facebook has your email list, it’ll invite the fans and contacts of your choice to like your Facebook page.
GET A BADGE
A badge is a dynamically updating clickable link to your Facebook page.
You can place it on a blog or on your web page. Just click on this link: https://www.facebook.com/badges/page.php.
ADD A LIKE BOX TO YOUR WEBSITE
Adding a like box to your website makes it easy for people on your site who wouldn’t otherwise see your Facebook page to easily like your page. You can access all the information here https://developers.facebook.com/docs/reference/plugins/like-box/
Just specify how wide you want your page, the color scheme and a few other options, then click “Get Code” to add the like box to your site.
These are Facebook’s built-in marketing features. Using them, you can market your page throughout Facebook using ads, invite existing fans of your business, put badges and like boxes on your site, market offline with aliases and message all your Facebook fans with updates.
