AIDA stands for Attention, Interest, Desire, and Action. It's a classic copywriting formula that helps you structure your ad copy in a logical and persuasive way. First, you need to grab your audience's attention with a catchy headline, an eye-catching image, or a shocking statistic. Then, you need to generate interest by explaining how your product or service can solve their problem, address their pain point, or fulfill their desire. Next, you need to create desire by highlighting the benefits, features, and social proof of your offer. Finally, you need to prompt action by using a clear and strong call to action that tells your audience what to do next.
