In the Web Page Activity and Company Web Activity reports you can see either anonymous or known people who visit your site. The anonymous people have inferred data, such as Metro Area.
Here's how to select whether the report displays known or anonymous people.
In your Web Page Activity report, click Setup.
Double-click Activity Source.
In the popup, select Known or Anonymous from the drop-down list.
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.
That's it. Click the Report tab to go back and view your report with known or anonymous people.
