I have been museum smm for 5 years

Typical museum posts are:

Museum objects (a must!!) with info about them

Schedule

Highlights, events, master-classes

Programs for young and adults

Main calendar dates

Cross-post with similar museum (strongly recommend)

You should regulary rotate this content, – different museum objects, diff calendar dates, you got it. The you start to create new types of content – interviews, polls, inside of museum work, etc.

Sorry for my english, not native.
