The primary objective of this study is to present a model for the effectiveness of spiritual and religious tourism marketing in influencing tourists' visit intentions in the digital age, employing a meta-synthesis approach. This research is developmental in nature, qualitative concerning data type, and utilizes a documentary-meta-synthesis methodology for data collection. The Critical Appraisal Skills Programme (CASP) can be employed for evaluating the articles. Based on 60 selected articles from reputable scientific databases, covering domestic sources from 2011 to 2025 and international sources from 2000 to 2026, information extraction was conducted from the results and analyses of these articles. After individually assessing each article, 24 were ultimately approved and screened. Subsequently, a new conceptual model was designed by reviewing the backgrounds and models of the approved articles. For the category of religious tourism, three indicators were extracted: sustainable development (economic development, community development, local development); infrastructure (destination image, destination appeal, perceived quality, perceived value); and motivation indicators (cultural, social, religious, personal). Additionally, for the category of spiritual tourism, two indicators were identified: spirituality in tourism (achieving meaning, attaining transcendence, achieving mutual understanding) and tourism marketing (political marketing strategy, religious marketing strategy, commercial marketing strategy). The extracted indicators within the framework of the proposed conceptual model can influence tourists' visit intentions. It is recommended that future research further examines the proposed model.
