My Facebook group focused on providing free access to online courses. Given the group’s objective, I promoted free courses and trial programs from education platforms such as Coursera and Treehouse. I occasionally promoted items that members may have found interesting like Grammarly, a free online grammar checker, and TubeBuddy, a free YouTube channel building tool.
And while you’re at it -- don’t create an additional public, “professional” profile associated with your business. For example, I already have a personal profile on Facebook that I largely keep private; the practice I’m talking about would be if I created a second, public one under the name “AmandaZW HubSpot,” or something along those lines. People usually do that to connect with professional contacts on Facebook, without letting them see personal photos or other posts. But the fact of the matter is that creating more than one personal account goes against Facebook's terms of service.
