In digital campaigns, reach refers to the total number of unique users who saw your content or advertisement. It measures the breadth of your audience, essentially how many distinct individuals encountered your message at least once. Impressions, conversely, represent the total number of times your content was displayed, whether by one person seeing it multiple times or many people seeing it once. Therefore, one unique user can generate multiple impressions if they see your ad more than once across different contexts or times. Understanding this distinction is crucial: reach indicates audience size, while impressions show content visibility and frequency. Both metrics are vital for assessing campaign performance, with reach highlighting awareness and impressions reflecting exposure levels. More details: https://info-hit.top
