I just discovered this and I can see how this is going to be a huge help with my blog and Etsy site. I like being able to see where and how my visitors go and browse my sites. It helps me with tagging, rearrange your shop, and to see what catches people's eyes.
You'll want to click these images to get them bigger, but on the left side below Dashboard click on Content.
Then click on Content by Title. This is good to look at anyway because you can see at a glance what is popular. Then click on the title of the page that you want to see the navigational summary for.
Then in the drop down menu select Navigational Summary.
On the next page you'll see the links that refer to your site and their percentages of link with arrows to the current page and then arrows to exit pages.
Pretty cool, huh? Now you can follow your visitors right through your blog or website and see what's working and what's not.
