Well, that all depends on how busy you’ve already been putting together the pieces of your course marketing plan.  If you’re just getting started there’s is work to be done!  However, if you have already started on putting pieces together such as building out a blog, creating a Facebook topic group, educating yourself on Facebook ads, and generally building a contact list and social following, then it’s just a matter of systematizing and optimizing your online course sales funnel.
As people progress through your funnel, their intent to buy steadily increases. You always lose people with each new commitment you ask for (we refer to these actions “conversions”), but the more people you can get to convert at each step in your funnel, the more sales you will ultimately produce. In marketing, we call this process “widening the funnel.”
If you're wondering what a sales funnel is, simply imagine a real-world funnel. At the top of that funnel, some substance is poured in, which filters down towards one finite destination. In sales, something similar occurs. At the top, lots of visitors arrive who may enter your funnel. However, unlike the real-world funnel, not all who enter the sales funnel will reemerge out from the other end.
