Aprendum is a web portal that offers online courses, workshops and seminars in many different subject areas with discounts of up to 90% and the possibility to access degree and certification courses from a wide range of training centres. Founded in 2011 by Juan Salcedo, the company has experienced meteoric growth in just three years. It has already exported its services to five countries in South America and has just launched in Brazil, a market with enormous potential. As a result of its international expansion, turnover has grown considerably and the number of staff members has increased from two to 16, plus four external contractors. Google AdWords has been and continues to be a very important tool for Aprendum, generating between 75% and 80% of its total revenue. AdWords also allows them to accurately calculate the return on investment of their campaigns, which is crucial for penetrating new markets. Juan says, “If used wisely, AdWords is an extremely powerful tool.”
