Link Shorteners to track your links
Being limited to 142 characters, the first few in an email preview, etc. every character counts. Why not count how well your items are shared, your events, etc.? Use a link shortener such as Google’s: goo.gl and bit.ly
Once you have a quickie account set up, you can create your own shortened links. bit.ly offers you the ability to customize them, as well. This is great if you are tracking hashtags and short phrases:
becomes http://goo.gl/tG6DkG or http://bit.ly/wpp-slma on bit.ly with a bit of customization.
Add notes so you know what they were links to and for your visitors.
