The marketing funnel AIDA stages are a marketing strategy that has been around for decades. It is used to help marketers understand how they should be approaching their marketing campaign in order to achieve the best results. The AIDA model is made up of four stages: awareness, interest, desire, and action. Awareness is the first stage where you need to get people’s attention and generate interest in your product or service. The second stage is where you need to create desire for your product or service by offering more information about it. This is followed by action which requires a call-to-action so that customers can buy your product or service.
