Google offers to help you with auto-activity-analytics
“Every day we aim to make technology so simple and intuitive that you stop thinking about it—we want Google to work so well, it just blends into your life. But sometimes it’s helpful to step back and take stock of what you’re doing online.
Today we’re introducing Account Activity, a new feature in your Google Account. If you sign up, each month we’ll send you a link to a password-protected report with insights into your signed-in use of Google services.
For example, my most recent Account Activity report told me that I sent 5 percent more email than the previous month and received 3 percent more. An Italian hotel was my top Gmail contact for the month. I conducted 12 percent more Google searches than in the previous month, and my top queries reflected the vacation I was planning: [rome] and [hotel].”
