If customers can't find it, it doesn't exist. Make a list and clearly describe the services you offer. Also, be sure to highlight a special service. 

Are you going to have a sale ?, the visit of a famous person or a special event? Announce it so that everyone knows it and creates expectation about it.

Your customers talking about you on social media? Share your stories to turn potential customers into loyal customers.

Are you going to have a special sale for the holidays or a weekly offer? Promote it here so your customers can see it and take advantage of the opportunity.

Did you open a new store, did you change the store decoration or did you add a new product or service? Tell people.

Customers have questions, you have answers. Show the most frequently asked questions, for everyone's benefit.
