Real-time marketing is when businesses run campaigns that happen very quickly in response to what's happening in the world. It means that companies can create messages that react to current events and show customers that they're aware of news and trends. It can help them to stay relevant and appear up-to-date with the world. For example, if a popular celebrity posts something on social media, a business could create a campaign that references that post. It gives them the chance to get people's attention quickly and can be a great way to promote their brand.
