Question

When companies recruit people to promote products to friends and other contacts in exchange for free samples or other​ rewards, without requiring them to disclose the true nature of the​ communication, it is referred to as​ "________ marketing."

Answer 1

The answer is: Referral marketing

Step-by-step explanation:

Referral marketing is like word of mouth marketing, but with a reward.

We are all social creatures, some more than others, and we like to tell our friends about things that might be considered interesting, new, good, etc (a little gossip). We also know by now that advertisement is usually not 100% accurate, so we don´t fully trust it. When one of our friends tells us that they tried product X and it was great, we do trust them and probably will end up buying product X.
