There are automatic sharing options available directly through Typepad. These are established in your blog SETTINGS.
See Typepad Support on sharing.
Some clients use a third party sharing application known as If This Then That or IFTTT.
If you need support to re-establish connections or if you find your blogs are not sharing to social media as you expect, please see IFTTT support here: https://help.ifttt.com/hc/en-us
