When plotting out the content mix for your upcoming social media publishing schedule, promotional content about your organization should exceed roughly 1/3 of your overall content mix.
Step-by-step explanation:
This has been established through various experiments and tests run on promotional content, but if you are able to show just a third of your overall content mix to be shown as promotional content, it is seen that it creates the needed excitement in the people while also keeping enough in store to keep them entertained as you upload your content regularly.
Any more than this, leave you with less than enough content to share with the people, thus reducing the impact of the publishing as it goes on and any lower may fail to create enough enthusiasm in the people.
