Abstract

This research aimed to: (1) examine the levels of seamless user experience, social proof, perceived risk, trust, and electronic word-of-mouth (eWOM); (2) investigate the direct and indirect influences among these variables; and (3) develop a practical guideline model for Thai entrepreneurs in e-commerce businesses. The sample consisted of 500 Thai consumers with online purchase experience within the preceding six months, selected through purposive sampling. Data were collected via online questionnaires distributed on social media platforms and shopping community groups. The research instrument demonstrated high quality (IOC > 0.80, α ≥ .927, CR ≥ .928, AVE ≥ .758). Structural equation modeling was employed for data analysis. The findings revealed that all variables were rated at high levels, except perceived risk which was at a moderate level. The structural model exhibited good fit (χ²/df = 3.418, CFI = .969, TLI = .956, RMSEA = .070), explaining 33.8% of the variance in eWOM. Seamless user experience reduced perceived risk (β = -.201) and increased trust (β = .188). Social proof enhanced trust (β = .261) and directly influenced eWOM (β = .265). Perceived risk negatively affected both trust (β = -.488) and eWOM (β = -.249), whereas trust positively influenced eWOM (β = .271). These findings culminate in a dual-path practical model offering actionable guidelines for Thai entrepreneurs to design seamless user experiences and leverage social proof to foster positive eWOM.
