(1) Your account statistics pages lists all your hubs with the daily counts thru total ever counts.
(2) But you can get more detailed information by going to each hub and clicking the "stats" tab at the top (when you are logged in). That will also show you where the hits are coming from. It also shows you the keywords people typed into search engines to get to you. The search engines they used and additional hub metrics.
(3) The best of all is when you use Google Analytics (Don't confuse this with Google AdSense). Google Analytics will give you an enormous amount of data. Sign up for it if you don't have it and enter your Analytics ID in your account/earnings page.
