Customers who are physically in your target location 2. Customers who are in your target location, as well as customers who express an interest in that location. For example, if Chicago is your target location, this could be a user from outside Chicago searching for *\[keyword] in Chicago*. If Adalysis detects a significant difference in the CPA of these two groups of customers, you'll see an alert. By default, a 25% difference in the last 30 days will trigger an alert. View performance data straight from your alert to decide whether to exclude users who aren't physically in your target location. You can also customize your alert under **Audit** > **Audit settings** > **Prebuilt** > **Campaigns**.
