How much of the content posted to Pinterest is from retail or e-commerce websites? How much money can they make off these links? These are hot questions right now. I’ll get to them, but first let’s back up. Recently journalists have had a field day in thinking they found some new, hidden secret within Pinterest because the pinterest.com website utilized SkimLinks service to monetize the user generated content (Pins). Well, Pinterest has been using SkimLinks since around the time they initially launched. I should also point out many other sites also use SkimLinks and don't formally disclose it, as it can cause confusion to those uneducated in the affiliate space.
