You have to discover the balance yourself. Post different content types and frequency, but you can count on video performing 2x better than static content. There is such thing as excessive posting frequency. A lot of social media agencies/”experts” feel that posting every day, or multiple times a day is best practices. It may be for particular industry, or business, but it can also be detrimental to maintaining a healthy following. Just like excessive marketing emails, your facebook posts filling up a users newsfeed can be perceived as spammy.
