When you view a Roll-Up actions report, for example the « Pages » report, then we aggregate all URLs that have the same URL-path together. For example when two or more different websites define a path « /cart » or « /blog », then we group all metrics for these paths together across websites. Linking to one specific URL would be misleading as the data is actually based on several different URLs. Therefore we remove the URLs from some reports.
