Ulasan daring sebagai salah satu bentuk electronic word-of-mouth (EWOM) telah terbukti memotivasi konsumen untuk berbelanja melalui online marketplace di Indonesia. Namun, kebebasan konsumen dalam memberikan ulasan mengakibatkan terjadinya inkonsistensi kualitas informasi yang berpengaruh terhadap kepercayaan dan keputusan pembelian konsumen. Selain itu, masih banyak online marketplace yang belum menyediakan fitur untuk menyaring informasi yang relevan, terbaru, akurat, atau lengkap pada ulasan. Penelitian ini bertujuan untuk menganalisis bagaimana pengaruh dimensi kualitas informasi dari EWOM terhadap keputusan pembelian produk di online marketplace. Penelitian ini menggunakan pendekatan kuantitatif dengan melakukan survei terhadap 1.266 masyarakat Indonesia pengguna online marketplace yang pernah berbelanja dan membaca ulasan dalam kurun waktu tiga bulan terakhir. Data diolah dengan metode covariance-based structural equation modeling menggunakan AMOS 24. Hasil penelitian menunjukkan bahwa keempat dimensi kualitas informasi EWOM, yaitu relevance, timeliness, accuracy, dan comprehensiveness memengaruhi information quality secara signifikan. Selain itu, information quality memengaruhi social psychological distance dan trust secara signifikan. Lalu, social psychological distance memengaruhi trust secara signifikan dan memediasi hubungan antara information quality dengan trust. Selanjutnya, trust memengaruhi purchase intention secara signifikan. Terakhir, purchase intention memengaruhi purchase decision secara signifikan. Hasil penelitian ini dapat memberikan wawasan untuk membantu penyedia layanan online marketplace dalam mengembangkan fitur ulasan yang lebih baik.
