FAQs
1. What does reach percentage measure?
Reach percentage shows how much of your total target audience saw the campaign at least once. It focuses on unique people, not total impressions, so it is useful for understanding real audience penetration.
2. What is the difference between reach and impressions?
Reach counts unique people. Impressions count every exposure, including repeated views by the same person. A campaign can have modest reach but very high impressions when frequency is heavy.
3. Why does average frequency matter?
Average frequency helps you see whether exposure is balanced. Very low frequency may hurt recall. Very high frequency may create ad fatigue and waste budget before expanding audience coverage.
4. What is a good reach percentage?
A good reach percentage depends on campaign goals, audience size, budget, and timing. Awareness campaigns usually prefer broader coverage, while retargeting campaigns may accept lower reach with higher relevance.
5. Why compare against a prior reach benchmark?
A prior benchmark shows whether current media planning improved audience penetration. It helps you judge optimization progress, especially when targeting, creative mix, or budget changed between campaigns.
6. Can this calculator help with budget decisions?
Yes. Cost per reached person, CPM, and ROAS help reveal efficiency. These metrics can show whether your budget is expanding unique audience coverage or simply repeating exposure too often.
7. Should unique reach ever exceed total audience?
No. Unique reach should never be higher than the total defined audience. If it is, your audience size may be underestimated or your platform reporting sources may not align.
8. When should I use this calculator?
Use it during campaign planning, mid-flight optimization, performance reviews, and client reporting. It is especially useful when you need a fast view of audience penetration and efficiency together.
