Companies are always looking for new markets and new customer segments to increase their profit. Most customers of Chipolo, a company that manufactures and sells smart item finders, are between 35 and 44 years old. The purpose of this diploma thesis was to get to know and better understand the younger Gen Z, their values, hobbies, consumer habits, so that our marketing campaign would address them in a way that would intrigue and attract them to Chipolo products and consequently boost Chipolo sales. The goal of the thesis is to sell more of the discounted Chipolo Bundle products to young consumers. The theoretical part explains marketing and its components and explores the possibilities of social media advertising. In this section, we also defined members of Generation Z and presented the Chipolo company. The experimental part focuses on a survey conducted in English and Slovene, distributed around the world to participants aged 15 to 24. Contrary to our initial theory the survey revealed that younger people look for their belongings weekly. Based on findings from the survey and general facts about Gen Z, we designed a »Back to School« marketing campaign and communication material for social media advertising, an online newsletter, and our webpage. First we formed a media strategy where we defined what our message is and to whom will this message address to. The campaign focused on young people between the ages of 18 and 24 but with ads we re-targeted users aged 18 to 65+ who had previously visited the chipolo.net website. We then formulated a media plan, where we determined where, when and through which channels we would convey our message. We decided to advertise the campaign on Facebook and Instagram as we found that these are the two most popular social media platforms amongst the younger Generation Z. After the campaign we analyzed the sales from the chipolo.net shop and concluded that the goal was not met. The sales in our target group did not increase, in fact, none of the buyers of the bestselling product we discounted in the campaign came from this target group. Facebook, the most popular social media platform, generated more leads to the chipolo.net web page than Instagram, but overall, the organic searches from Google brought in most customers.
