Longer titles in push ads can work better for ecom offers if they are clear and give a full message. Some users may respond more when they see exactly what the offer is about without having to guess. A longer title can help explain the product, the benefit, and even include a small call to action. For example, something like "50% Off Smartwatch Today Only – Limited Stock!" tells the reader what the product is, the deal, and adds urgency. But at the same time, the title shouldn't be too long that it gets cut off or looks confusing. The main idea is to make sure the message is direct and easy to understand. Short titles can also work if they are catchy and grab attention fast. It may help to test both styles and see what people click more. What has been your experience with using longer or shorter titles?
