Anthill Inside 2019

The ad creative is the image of the ad that the user sees on their device. It includes information such as the image dimensions, its placement on the screen or within the app, the native resolution of the creative and the mobile screen it is displayed on and similar parameters. Why exactly a particular ad is visually appealing and another not is hard to determine. Using data from the performance of hundreds of thousands of creatives that Inmobi displays, we model the performance of an ad creative based on the objects in a creative and their relative positions and sizes. We use state of the art convolutional neural nets to detect objects, text, and logos in creatives and their positions. Our model is able to provide actionable insights to creative designers on how to modify the creative to improve its performance. In general, our approach would be useful for understanding how the composition of an image relates to any engagement metric chosen by a researcher or business.
