We can see in this video that one technique the advertisement is using is Testimonial: a famous person, in this case Juan Sebastian Veron, who claims the product is good.
The product is a yogurt, so the demographic targets are people of all ages. That`s why the character is with his father, an old person, and with his son, a child.
Another technique is Image Advertising. The place where the Ad takes place is a football field and the people are training.Therefore,the product is being associated with athetlic people and sport activities.
Finally, when Veron says "Con Yogurisimo , hay Brujita para rato" the Ad is encouraging people to consume the product to extend their physical states.
