When publishing links Postcron will automatically shorten them using Google Shortener.
We advise you shorten your links when publishing to several accounts in order to prevent them from getting blocked by spam.
The URLs you paste on the Publisher will be first shortened with Google, and then, if you have a Bit.ly account associated to Postcron the link will be shortened again when published. The link you must check is the one after publishing and on the social account you selected it on.
You can connect your Bit.ly account going to My Account >> Social Accounts >> URL Shortener
