If you have built your Fit Pro biz on Facebook you are wide open for failure..
It’s someone else’s platform, yes use it, and use it well but you should still have your own domain name, hosting and real estate online.
My advice is to get a basic wordpress website, decent hosting and start posting your articles on your site, use your social media streams to drive traffic to your site.
There are exceptions of course, vids hosted direct to facebook are a necessity, but by and large it should be all on your own site.
If you need any help with all this let me know and we can get you started,
