Ad Reach and Ad Impressions measure different dimensions of advertising exposure, though they're often misunderstood. Ad Reach counts the unique individuals or households who have been exposed to your advertisement at least once during a campaign period, providing insight into the size of your audience and campaign breadth. Ad Impressions, however, tracks the total number of times your ad was displayed, regardless of whether it was seen by the same person multiple times. Essentially, Reach tells you how many people saw your ad, while Impressions tells you how many times your ad was shown in total, including repeated views by the same individuals.
When launching a brand awareness campaign for a new product in the Canadian market, prioritize tracking Ad Reach if your primary goal is to maximize exposure to unique potential customers. For instance, if you have a limited budget and need to introduce your brand to as many new consumers as possible, optimizing for Reach ensures you're not repeatedly showing ads to the same people. Conversely, when running a conversion-focused campaign for a complex or high-consideration purchase, monitor Ad Impressions carefully. For example, if selling luxury watches or investment products, your audience typically needs multiple exposures before taking action. In this scenario, achieving high Impressions relative to Reach (known as frequency) becomes more important, as it indicates that your target audience is receiving the repeated messaging necessary to move them through the decision-making process.
