What is Content pillars?
Content pillars are an account’s recurring themes: a small set, usually three to five, covering what the brand knows, what the audience wants and what the brand sells. They solve the daily question of "what to post today": every post belongs to a pillar, and planning spreads the pillars across the week. They also build recall: an account that always talks about the same subjects becomes a reference in them, for the audience and for the algorithm.
