Reviewing ad extension performance in Paid Search is critical because it helps advertisers understand how specific extensions are impacting campaign effectiveness and user engagement. Reviewing performance data helps you test different extensions and combinations, allowing marketers to allocate budget and resources to the top-performing extensions that maximize return on ad spend (ROAS). This work often requires manual effort, increasing the risk of overlooking important insights. It can also be time-consuming, taking away valuable team hours that could be spent on optimizing campaigns for best results.
