This empirical research examines the effects of Thai online travel agencies’ banner advertising belief factors on inbound tourists’ attitude toward banner advertising and the effects of inbound tourists’ attitude toward banner advertising on banner advertising effectiveness. The results of structural equation modeling can partially confirm the belief-attitude-effectiveness relations for Thai online travel agencies’ banner advertising from the perspective on inbound tourists. The empirical results from this study indicate that the features and contents of banner advertising in terms of hedonic/pleasure, credibility, social role and image, good for economy and interactivity can lead to favorable attitude toward banner advertising while the irritation feature of banner advertising can create unfavorable attitude toward banner advertising. Furthermore, favorable attitude toward banner advertising is likely to increase effectiveness of banner advertising. This study suggests a banner advertising management model for effective online advertising tasks to drive business survival in the international tourism marketplace.
