Q: Many social networking sites allow you to share your interests with friends and followers by clicking a button or sharing a link to show that you’re a fan of a particular business, product, website or service. Is that an "endorsement" that needs a disclosure?
A: Many people enjoy sharing their fondness for a particular product or service with their social networks.
If you write about how much you like something you bought on your own and you’re not being rewarded, you don’t have to worry. However, if you’re doing it as part of a sponsored campaign or you’re being compensated – for example, getting a discount on a future purchase or being entered into a sweepstakes for a significant prize – then a disclosure is appropriate.
