I read the "how we make money" section, but I have additional questions about the affiliate links.

1) does just clicking (not purchasing) provide revenue?

2) When a post has several links, presumably not all are revenue generating, is there a way to tell which ones generate revenue?

3) what's the process for choosing, using, endorsing, and linking back to the products?

ex: do you use a product on your own and then contact the retailer before sharing it on the blog? Or a retailer introduces you to a product and that's why you use it an include it in a post?

4) What if a product is purchased because someone saw it on HB, but didn't link? Is there a way to track that or tell the retailer about the HB referral?
