Despite the fact that Lazada is one of the largest e-commerce business, the number of its visitors decreases every year. This phenomenon is related with the drop of its customers’ response to the company in making purchases. The objective of this research is to identify the effects of the use of key opinion leader and online customer review on the increase of purchase decision through customer trust. The sample of this explanatory research was selected using non- probability sampling method and purposive sampling technique. Using the criteria of Indonesians with the minimum age of eighteen years who have made any purchase through Lazada and have seen key opinion leader promotional contents about products sold in Lazada, 140 people were selected as the respondents. The data was analyzed using Structural Equation Modeling (SEM-PLS) in SmartPLS 3.0. The results of the testing on the seven hypotheses indicate (1) that key opinion leader positively influences the purchase decision, (2) that online customer review positively affects the purchase decision, (3) that key opinion leader positively impacts the consumer trust, (4) that online customer review positively influences the consumer trust, and (5) that consumer trust positively affects the purchase decision. Therefore, this research concludes that key opinion leader and online customer review are able to improve purchase decision with the mediation of consumer trust.
