Here is how to auto-post from Facebook to Google My Business.
Many people have requests like this:
I want to post to Facebook natively, but then have that post automatically go to Google My Business posts as well. (Or vice versa)
Here is how to do it with OneUp.
First, you must go to RSS.app (which is free) and create an RSS feed of the social account you want to post FROM.
Then copy your RSS feed URL
After, go to OneUp, and in the Schedule Post dropdown, choose “Auto-post from RSS feeds”.
Paste in the RSS feed URL that you had copied, then choose the category and which account(s) you would like to auto-post to.
Choose your Call-To-Action button and add your button URL.
Now whenever you post something on Facebook, you can have it automatically published on Google My Business posts.
For the other way around, just create an RSS feed of your Google My Business posts and select them to be posted to Facebook.
