In the tracking box, it is either you type in your email or you type in the link you shortened, if you remember it. The link field can accomodate the long address and the shortened address. Whichevern data you have can help find your link.
The implications of the fields filled are:
If you typed in just your email address, every link you have shortened with that same address will be shown so that you can select the link you want to track.
If you typed in just a link, every link from anyone that points to the address you typed in will be shown, irrespective of who shortened it.
If you include your email and the link, only that single link which have been shortened by you will be shown. Therefore, if you include your email, you increase the precision of showing your own link.
As soon as you find your link, just click on it and you will be taken to the Analytics page where you can track clicks on it.
If you need to track Referrer from a specific website (dorotv.com for example), that is where the click came from, this is how to: Type in dorotv.com in the field. Clicks from any page, even from dorotv.com/v/1000 will be shown. But if you type in dorotv.com/v/100 Only clicks from that exact url will be shown. Therefore, use domain name(dorotv.com) to track all clicks and include sub directories when you need to track specific pages.
If you need to track IP address, just type in the address. Maybe you need to know how many clicks came from a particular network or office whose IP is 110.199.212.001, type in 110.199.212.001 and you will see the clicks. If you type in anything short of a complete set of IP address, any click with IP that matches that criteria will be shown. Example, if you type in 110.199. and search, the following IPs could be shown: 110.199.212.001, 110.199.213.001, 18.104.22.168 etc, as long as it has 110.199 in it.
