Introduction
Online ads are essential to all businesses, and ad headlines are one of their core creative components. Existing methods can generate headlines automatically and also optimize their click-through-rate (CTR) and quality. However, evolving ad formats and changing creative requirements make it difficult to generate optimized and customized headlines.
COBART Method
We propose a novel method called COBART that utilizes prefix control tokens along with BART fine-tuning. This method yields the highest CTR and allows users to control the length of generated headlines for use across different ad formats.
Additionally, it is flexible and can easily be adapted to other architectures, creative requirements, and optimization criteria.
Experimental Results
Our experiments demonstrate a 25.82% increment in Rouge-L and a 5.82% increment in estimated CTR over previously published strong ad headline generation baselines. This indicates a significant advantage of this method in ad headline generation.
Blogger's Review: The COBART method introduces prefix control tokens, addressing the flexibility and optimization needs in ad headline generation. Its improvement in CTR provides advertisers with more effective strategies, making it a noteworthy advancement for further exploration.
