The type of research used in this study is a quantitative approach. The sampling technique used is purposive sampling.

Based on the hypothesis testing that 1) Digital Marketing (X1) has a positive and significant effect on purchasing decisions with a calculated t-value of 4.046, it is known that the calculated t-value is greater than the t-table value (1.988). And the p-value in the sig column is 0.010 < 0.05, which means it has a significant effect. 2) Viral marketing (X2) has a positive and significant effect on purchasing decisions. This can be seen from the significance value of 0.023 < 0.05 and the calculated t-value of 7.054 > t-table value (1.988). 3) Digital Marketing (X1) and Viral Marketing (X2) simultaneously have a positive and significant effect on purchasing decisions. This can be seen from the calculated F-value being greater than the F-table value and the significance level (0.000) being less than 0.05.]]>
