From the Item Listing Page
At the bottom of any item listing page, you can view the number of views/clicks on any item in the "LISTING VIEWED X TIMES" section just above the site footer.
Keep in mind that views/clicks on your own items (when you are signed in to your account) will not be recorded.
From the Members Area
If your listing has views/clicks this information will also be shown under the Listing Title as "X views" in the the Members Area > Selling > Listings page:
Note that if your listing does not currently have any views/clicks no information will be displayed (it will not say "0 views").
