Changing banner ads often can help keep your campaigns fresh and prevent people from ignoring them. If someone sees the same banner too many times, they may stop paying attention. A good idea is to update your banners every couple of weeks or at least once a month, especially if you're running ads to the same audience. You don’t always need to create a brand-new design. Sometimes just changing the colors, text, or images can make a difference. If you notice performance dropping, that could also be a sign it's time to switch things up.
