Frequency

Frequency is one of the core delivery metrics of any paid social or display campaign. Mathematically, it is total impressions divided by unique reach over the same time window. A frequency of 1.0 means every impression went to a different user, which is rare; values between 1.5 and 4 are typical for healthy campaigns. Beyond a certain point, additional exposures stop adding lift and start eroding performance—a pattern called creative fatigue. The right frequency depends on goal and audience: awareness campaigns benefit from low frequency and broad reach, while consideration and retargeting campaigns can absorb higher repetition because the user has already shown intent. Marketers typically watch frequency alongside CTR, CPM, CPC, and conversion rate to know when to refresh creative, rotate angles, or expand the audience. In the SMM panel context, repeatedly boosting the same post can artificially raise frequency for a small core audience, which is fine for short-term proof signals but ineffective for long-term reach building.
