Digital marketers usually plan campaigns around sales periods, product launches, and special events before they happen. A promotional calendar is simply a schedule showing when discounts, offers, or events will run during the year. Since plans can change often, marketers regularly update ad text, keywords, and landing pages so customers always see the latest information. Some businesses even pause ads immediately after an offer ends to avoid confusion. Careful timing also helps control ad spending because money is not wasted on expired promotions. How do you think businesses handle sudden changes during active campaigns?
