The biggest use people have for LinkTrack is as a link shortening service. If you take a long link like:
http://maps.google.com/maps?f=q&hl=en&geocode=&
q=124+Grapevine+Hwy,+Hurst,+TX+76054
&sll=37.0625,-5.677068&sspn=49.978077,92.8125&ie=
UTF8&ll=32.871721,-97.16844&spn=0.0065
24,0.01133&z=17&layer=c&cbll=32.870212,-97.168443
You can shorten it so it looks like this:
As an added bonus, you can track how often that link has been clicked on. Each page gets its own tracking page like this one.
I used this the other day when I was meeting with a client. After I sent him directions, I was able to follow up on the tracking page to see that they had accessed them.
