I have two websites that need the same blog posts on them and I am wondering if it is possible to post to one blog and have the post automatically duplicated on another blog that I own…any suggestions?
It isn’t. Each blog is unique 
With the blog app it’s not possible, but otherwise it is 
Are both websites Wix websites? It may be possible if one of them is not a win website
What you could do is create your own blogs via Corvid and connect them to an external database that updates both of them.
Interesting! Thank you for this information.
