Make the most out of your Personalization campaigns using Guardian.

- **[About Guardian](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_guardian_about.htm&release=264.0.0&type=5)**  
    Guardian continuously monitors thousands of metrics that it gathers from your site, web application, or mobile app. It uses these metrics to discover current trends, identify potential issues, and surface optimization opportunities. Guardian is part of Personalization, so there’s nothing to set up or configure for it to recognize what's important to your business.
- **[Guardian Metric Types](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_guardian_metric_types.htm&release=264.0.0&type=5)**  
    Personalization’s Guardian constantly monitors your site for several metrics. Understanding what Guardian is measuring is critical to understanding the information it displays about your site or your app.
- **[Use Guardian Topics](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_guardian_topic_view.htm&release=264.0.0&type=5)**  
    Guardian topics are groups of user behaviors that Guardian uses to predict positive or negative impacts on your website.
- **[View Guardian Signals](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_guardian_signal_view.htm&release=264.0.0&type=5)**  
    Signals are Guardian’s way of alerting you when a metric falls outside of a predicted range for the seasonal daily and weekly activity for your site and dataset. Using signals, Guardian can provide either positive or negative indications of how metrics are impacting your digital property.
- **[Adjust Guardian Notification Settings](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_guardian_notification_settings_adjust.htm&release=264.0.0&type=5)**  
    You can adjust Guardian notification settings to customize the email alerts you receive based on what’s most important to you. Guardian automatically sends notification emails to anyone @mentioned using the Add Comment feature for any metrics.
