Images, Captions, and Overlays in Social Media Brand Posts: How to Strike the Right Balance in Multimodal Compositions
Digital managers struggle to determine which images, text in overlays (customized text format within the image) and captions (standard text format above or below the image), are more likely to boost sharing and increase consumer engagement. They might gain relevant insights from research on visual salience that explicates the influences of multimodal compositions on human behavior. This article reports on two experiments that show that more salient, dynamic images, get shared more than static ones, due to the greater degree of consumer attention. Then separate Twitter and Instagram studies, using social media data, extend these findings by revealing the relationship between image dynamism and salience features related to the size and emphasis of text in the overlay and caption. We find that while greater overlay size weakens the effect of dynamic images on consumer sharing, greater caption size (i.e., length) increases it. We also find that placing the overlay in strategic areas (i.e., rule of thirds) and emphasizing strategic words in a caption, strengthen the effect of dynamic images on sharing. These findings establish some basic heuristics that content managers can use to design effective, multimodal brand messages.
