Knowing how to syndicate and repurpose content is essential for any content creator. You can only write or create so much original content, so re-sharing what you have in different ways across different platforms will help get the most exposure and value from your work.
I know I haven't been doing this well, so I will take the advice of Douglas Lim in this article to use IFTTT to set up auto-syndication of my blog posts.
What I like about IFTTT as Douglas describes it is the ability to customise the updates that are shared so that they fit different platforms.
