The Overview dashboard is the first thing you see when you log in. It shows four key numbers for your selected date range: Total Revenue, Customers, Leads and Avg LTV (average lifetime value per customer).
You can filter the Overview by date range, channel or campaign to narrow the numbers down to a specific slice of your marketing.
If your account has more than one website, use the site switcher to move between them — each site shows its own Overview numbers.
