According to many communication experts, the priority should be given on these:

#Linkedin, personal and company page: daily use, one post a week.
#Twitter, posts automatically sent from Linkedin
#Instagram: Posts/Pictures are published bi-weekly
#Facebook and #Messenger with personal and company page. The context here is more informal but it has to be in line with the other #socialnetworks.
#YouTube: the new frontier for my communication.
