Reach refers to the total number of unique users who have seen your ad or content at least once during a campaign. Unlike impressions, which count total views (including multiple views by the same person). Reach focuses on distinct individuals, making it a key metric for measuring audience exposure and business visibility.

• Indicates brand visibility across the target audience.
• Helps assess how wide or narrow your campaign distribution is.
