If you would like to take a more subtle approach, include a product or service from your company that relates into your blog post. For example, let’s say that you are a wine connoisseur and that is what your blog is based around. In any post that is enticing your readers to open up a good bottle of Merlot or what have you, it would be wise to embed an ad for a quality, easy-to-use wine opener, wine glasses or stoppers that keep the wine fresh.
When you place an affiliate link on Facebook, you need to be clear that you’ll get paid if someone clicks on your link and purchases the product. There’s no specific terminology you need to use, but it does have to be clear that your link is an affiliate link. Even saying something as simple as “This is an affiliate link” before you place the link can suffice.
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.
