Advertising exists to draw you in and attract you to what is being sold. Therefore, an ad headline needs to be compelling. Here are some tips and tricks for writing ad headlines:
Include a keyword for clarity, so that a potential customer immediately knows what you sell. Suggest that a problem will be solved. People want functionality; thus, you need to create the perception that your product or service can uniquely help them. Also, adding a little humour is a good idea in most cases.
