Such software is really meant to help you manage client flow and thus yield/return management. In other words, fill in gaps/time with business albeit at discounted rates. It is not really meant to market/advertise your business. thus the traffic you get is a result of the discounted rates, not so much campaigns run on your behalf.
Schedulicity is an online booking service. It won't generate traffic on your site. If you own a website, you can use scheduling modules on it. They're not hard to integrate with most content management systems.
Scheduling options on your site won't bring more traffic, but it will surely make it look more professional.
