Here's how to select whether the report displays known leads or anonymous visitors.
1. In your Web Page Activity report, click Setup.
2. Double-click Activity Source.
3. In the popup, select Known Leads (people) or Anonymous Visitors from the drop-down.
Including ISPs for anonymous visitors generates a longer report, but excluding them provides a clearer view of where your visitors are coming from besides the standard sources, such as Google.
4. That's it. Click the Report tab to go back and view your report with known or anonymous people.
