L.A. mentioned using Bit.ly as a url shortener on Wednesday. She was dead right - it's by far the best shortener out there because it gives you some neat analytics to measure how much interaction you get on the link.
And here's a tip..... Instead of pasting a link in the 'Link' box when you share an item, shorten it in bit.ly
and paste the shortened link at the end of your text. Then, use the 'add photo' option and find a really eye catching photo. You'll get far more interaction. #strategytips
