During the campaign’s lifetime, this defined audience can grow in size. But, usually, this will remain consistent, and the frequency will start to increase. For example, once we know the frequency has gone over a particular mark, we know the audience has been defined. Prior to hitting the mark, the campaign is still in what we internally refer to as the discovery stage.
To hit our goal, we want to ensure the audience sees the ad in the sweet spot between it grabbing their attention and them becoming disinterested as they have seen it too many times, which is defined as creative fatigue. This varies based on the audience and the product. We want to generate more awareness. However, we want to avoid creative fatigue. We want to remain within this sweet spot to encourage users to take action – for us, this was to complete a form. If the campaign goes above our sweet spot, the cost per lead will increase and trigger a need to be reviewed to resolve the creative fatigue issue – which means the audience has seen the ad too many times they will ignore the ad.
Throughout the campaign, enrolments increased across Inspire’s venues for various courses, including accountancy, law and management. Once the campaign concluded, Inspire decided to bring future social media advertising in-house under their internal marketing team.
