This feature identifies sudden spikes or drops in impressions and clicks for a site's top pages. These fluctuations may indicate changes in content demand or technical issues like broken redirects. Users can receive alerts via email forwarding and provide feedback on the alert sensitivity in help forums. The goal is to help users identify critical changes that may need investigation.\n"]]
