From Spacing to Scheduling: The Effect of Seller Posting Time Strategies for Short Video Advertising

Yuan, Lin, Gene Moo Lee, Hao Xia, Qiang Ye. “From Spacing to Scheduling: The Effect of Seller Posting Time Strategies for Short Video Advertising”, Accepted at CIST 2023.

We examine how a seller’s posting time strategies of short video advertising affect consumer engagement and product sales. Drawing on the two-factory theory, we develop hypotheses on the effects of ad spacing and scheduling on ad effectiveness. The empirical results based on a unique short video ad dataset from Douyin, the Chinese counterpart of TikTok, indicate that there exists an inverted U-shape relationship between ad spacing and sales. Also, certain posting times significantly increase ad effectiveness. Interestingly, the effects of posting time strategies manifest under specific conditions: the effects of ad spacing on consumer purchase are strengthened for products with higher discounts, while this moderating effect is diverse for different posting times. These results provide nuanced insights to help ad managers make strategic decisions on ad posting times in the important context of social commerce.

This research methods article proposes a visual data analytics framework to enhance social media research using deep learning models. Drawing on the literature of information systems and marketing, complemented with data-driven methods, we propose a number of visual and textual content features including complexity, similarity, and consistency measures that can play important roles in the persuasiveness of social media content. We then employ state-of-the-art machine learning approaches such as deep learning and text mining to operationalize these new content features in a scalable and systematic manner. For the newly developed features, we validate them against human coders on Amazon Mechanical Turk. Furthermore, we conduct two case studies with a large social media dataset from Tumblr to show the effectiveness of the proposed content features. The first case study demonstrates that both theoretically motivated and data-driven features significantly improve the model’s power to predict the popularity of a post, and the second one highlights the relationships between content features and consumer evaluations of the corresponding posts. The proposed research framework illustrates how deep learning methods can enhance the analysis of unstructured visual and textual data for social media research.
