In advertising, what does the term "frequency" refer to?

Frequency in advertising specifically pertains to the number of times an advertisement is shown to a particular user or audience over a specific period. This metric is crucial as it helps advertisers understand how often their message is being delivered to the same individuals.

Understanding frequency is important for several reasons:

1. Repetition and Recall: A higher frequency can enhance brand recall. When a user sees an ad multiple times, they are more likely to remember the product or message.

2. Ad Fatigue: While frequency can aid in brand recognition, it also has to be managed carefully. If a user sees the same ad too many times, it can lead to ad fatigue, potentially causing negative feelings toward the brand.
