While I haven't worked on an influencer marketing campaign, my job as a cashier has given me insight into how customers' purchasing decisions are influenced by promotions, trends, and payment options. For example, at my current job we don't accept Apple Pay, and I've seen many customers abandon their purchases due to limited payment options.

You should clearly define the campaign goals and identify your target audience to select the right influencer. The influencer should have an audience that aligns with the one you are trying to reach.
