# What are content pillars? Canonical page: https://depost.ai/glossary/content-pillars **Content pillars:** Content pillars are the three to five recurring subjects a person or company posts about, chosen in advance so that individual posts accumulate into a recognisable position instead of reading as unrelated updates. Also called: content themes, content buckets, posting themes. The problem pillars solve is memory. Nobody remembers a single post, but people do remember that you are the person who keeps writing about pricing, or hiring, or why a particular practice is broken. That association only forms through repetition on a narrow set of subjects. Three to five is the usual range for a reason. Fewer and you exhaust the material and start repeating yourself literally. More and no single subject appears often enough for anyone to connect it to you. Good pillars sit where three things overlap: what you genuinely know, what your audience needs, and what supports the outcome you want. A pillar that fails the first test runs dry fast, and one that fails the third produces an engaged audience that never becomes anything. They are also a planning device, not a cage. The point is that a reader can describe what you write about after following you for a month, not that every post must be filed under a heading. ## In Depost AI Pillars are part of the brand memory every agent reads. Onboarding drafts them from your profile and published posts in about fifteen minutes, you correct what is wrong, and from then on the Idea Generator plans against them rather than against whatever is trending. ## Questions people ask ### How do I choose my content pillars? Look backwards before you plan forwards. Read the posts that produced real conversations, the questions you get asked repeatedly, and the objections that come up in sales calls. The pillars are usually already visible in that record. ### How often should I change them? Rarely. Pillars work through repetition, so changing them every quarter defeats the purpose. Revisit when your business changes, not when you get bored of them, which will happen long before your audience does. ## Read next - [How brand memory works](https://depost.ai/features/brand-memory) - [Building a LinkedIn presence](https://depost.ai/blog/linkedin-content-creation) ## Related terms - [Brand memory](https://depost.ai/glossary/brand-memory): Brand memory is the stored context an AI content tool reads before it writes for a particular person or company: their positioning, their voice, what they have published and how it performed, the reference material they have saved, and the preferences they have stated, kept across sessions instead of being re-entered with every prompt. - [Brand voice](https://depost.ai/glossary/brand-voice): Brand voice is the consistent set of choices that makes writing recognisable as coming from a particular person or company: vocabulary, sentence rhythm, how formal it is, what it refuses to say, and which arguments it keeps returning to. - [Content calendar](https://depost.ai/glossary/content-calendar): A content calendar is a forward view of what will be published, when, and by whom, used to turn posting from a daily decision into a plan that survives a busy week. --- Cite as Depost AI (https://depost.ai/glossary/content-pillars).
