The research aimed to determine the moderating effect of advertisement (ad) length on the relationships between ad content and the intention of skipping, as well as ad irritation. Previous research has discussed the factors that affect customers' intention of skipping and ad irritation, centering around the duration of an ad, and whether the ad is skippable. However, no previous research had focused on the relationship between the intention of skipping and ad irritation that consumers experience. The research attempted to fill in the lacuna in the academic literature on the said issue. In doing so, it examined consumers' responses towards the consumers' intention of ad-skipping and irritation. The experimental research utilized four video ads with varying durations and containing both entertaining and boring content, with long and short ad length. The research sample comprised 120 respondents spend at least more than 1 hour online. The research employed convenience sampling and the method of Univariate Analysis of Variance Linear Model. IBM SPSS Statistics was used for data analysis. The results reveal that the content and length of an online video ad have a direct effect on consumers' ad irritation and intention of skipping. The research concludes that the perceived entertainment of an online video ad significantly affects consumers' intention of skipping and ad irritation. Furthermore, the length of video ads has a major impact on their intention of skipping and ad irritation.
