Create a 2nd Facebook Business Page.
One could be for your Niche and the other for promoting WA and the other sites and programs that You share to earn an income.
I know what some of you are thinking.......another page? I just created this one, well when You have 2 Facebook Business Pages You can use 1 to promote and grow the other simultaneously.
Many times I will post a picture of maybe a motivating or uplifting quote then share it with the other page onto that timeline creating kind of a backlink sort of.
The other thing is that under the settings tab on the top right side when you click on that You can set Featured Page Owners and Featured Page Likes as well. That is where You would also cross promote each page.
You can also Like other Business Facebook pages with your Facebook Business pages
