Hi @ShellyM! There are a couple of ways to promote your Loyalty program, but keep in mind to enroll, your customers must visit your business. When they visit your business customers can enroll after a sale, or you can add their information to the app. There isn't a way for them to enroll to your Loyalty program online at this time.
To advertise your Loyalty program you can create and send Square Marketing campaign from the Customers section of your online Dashboard. When you create the campaign you'll see the option to share that campaign on Facebook too.
You can also send a campaign from the Loyalty of the your online Dashboard (navigate to Promotions), but that campaign is email-only and can't be shared on Facebook!
