Yes, you can link them to your fundraising page by simply copying the URL for the page into your message on Facebook. HOWEVER, please be warned that Facebook will ask after you posted the link if you want to ask your Facebook friends to support you, and you need to say no or decline as they (Facebook) have their own fundraising platform and people would be donating to Facebook’s platform. This will create a big problem. So again, post your link on your home page, but do not click on Ask friends to donate button even though it seems intuitively the correct thing to do.
