How you can benefit from a "Book" button
Imagine that a potential customer finds your Facebook page, but you do not have a "Book" button set up yet (also called "Call-To-Action" or simply CTA). Customers will have to use a search engine to search for your website and then browse through your site until they find the corresponding offer to make a booking. In any case, the customer has to click their way through your website until they find the booking page. A CTA button significantly shortens this process. The customer is transferred directly to your booking offer, making it more likely for him or her to actually make a booking.
By the way, did you know that you can directly integrate bookingkit in Facebook?
