Content pillars are the 3–5 core themes that all your content falls under. They give your channel a clear identity and make content planning much easier.
Educational content should be your most frequent pillar (40%) as it drives search traffic. Entertainment and inspiration share the remaining frequency. Keep promotional content under 20% to maintain trust.
Yes — as your channel grows, your pillars may evolve. Review them every 6 months. But avoid changing them too frequently as it confuses your audience and the algorithm.
