thanks to anya i recently discovered budurl, a great service to measure the power or reach of social networks, email campaigns, blog posts or simply giving you a short url and providing some great detailed metrics about when and from where people clicked on your url (referrer), budurl makes link tracking amazingly simple.
“what kind of power would you have if you could not only shrink a long url, but also add notes and tags along with detailed analytics like you have on your website? detailed statistics is marketing nirvana, but your website statistics only cover your website. what about social networks, emails, print marketing materials, presentations, etc. the list goes on and on! budurl gives you the power to quantify this traffic and make decisions that were once a shot in the dark.”
especially in combination with a service like ping.fm you can measure which of your social networks have any reach and which ones don’t. shorten the link, put it somewhere, watch it grow and measure the results. check it out at budurl.com
