I give gratitude to wragge11 for let me know about this option. Go to your Adsense account - Click Setup, Then Channels. on the channel page, you should see a link called "URL Channels". This is found next to your Custom Channels link. Click the URL Channel link, and then click ad a new URL Channel. Ad the URL address which your unit hang and you will slowly get a report to the chosen URL.
Channels are a huge resource. You can dissect issues right away. Using channels I improved click-through by almost double.
