Organic Post vs Shared Post in Groups for Business Pages on Facebook.
FYI: Followers and friends can share your post in their personal profile and their groups too. The question you may be wondering is what is best for my business.
The answer is: Neither and Both.
ORGANIC POST: If you are able to post as your business page then you should be posting organically (create) in that group. Remember, a link is already created for others to click on if they want to visit your business page. When you post organically, it shows other members you are engaged and speaking to the group one-on-one. You're likley to get more likes, comments and shares from other group members.
SHARED POST: Posting on your business page and then 'sharing' that post into groups is a great tool and saves time. However, don't be lazy about it and write something provided in the box to the group. They will read it and be less likley to bypass or scroll past a 'shared post'. Add a little something like this to promote your business and engage the group members.
"Today we are open at 11am and taking orders till 6pm for curbside pick-up. Call us to place your order 386-123-4567"
"It's Meatloaf Monday! A fan fav ! We're taking your phone orders starting a 11am for pick-up and delivery. 386-123-4567" Last call to order is 5pm and we close at 6pm."
Writing a message will engage the reader and viewer oppossed to just sharing the same message everywhere. Make it personal and fun, talk to the viewer both organically or with a shared post.
You see, neither is the best or worse but how you choose to do so, what the message is and how you respond to comments in that group.
