The most efficient and ancient marketing tool in the world that has been used since we have conscience is the word of mouth. When somebody within your social circle recommends you a place to go for holidays, an amazing blog to read or a resturant where to have dinner, most of the times we try to keep that advice in a special department in our brain. Why? We really trust on what our friend-next-door says and has experienced. And other reason might be that our human nature makes us want what others have already had. We try to keep up not missing out great things. Ok, but this is off-line terminology. How can you make people talk about you online product? In 2006 four young enterpreneurs founded a social network in Spain called Tuenti. Even though this young platform could only attract 10.000 users for the first year, they believed that their way of increasing the users rate was slowly but surely. How? The Invitation. Once a person belongs to the community has the right to invite five other friends and so on. In the beginning that was the only way they used to spread out the information about their product.  What impact does the invitation make on a target?

• Communication. The first time I heard about this platform was because someone invited me to come in.

• Creates expectations. You can not get into the social network until you are invited by somebody who is already in.

• Invitations are sent out among known people. Other reason to make you to get in. Your friends are there.

• Very cheap marketing tool. The users made all the work to spread out the word.

The amazing thing is that these invitations were whether offline or online mouth to mouth. People talked about how to get one of those on and off internet.

What happened to this Social Network? They sold 85% of the company to Telefonica, spanish telecommunication  multinational, for 80 million euros. And what about Facebook in Spain? They took advantage to be the fist social network in spanish language.

On October it has been announced that Tuenti.com has reached 12 million users.
