I have one question. Should I use short or long URLs when submitting my blog articles to social bookmarking sites?
If I keep submitting them every two days, does Google penalize my sites for submitting the same social sites every day, like Facebook, google plus?
If yes, should I use short urls instead?
If you're submitting them to social networks where you have followers, short urls may increase the number of clicks on your links.
If you are just doing it for backlinks, you can use the long url.
