Content pillars: how to decide what your brand posts about

Content pillars turn "what should we post?" into a repeatable system. How to choose three to five, test them, and use them to plan a month of content.

The most common reason brand accounts go quiet is a blank page: "what do we post today?" Content pillars solve it. A pillar is a recurring theme you post about, chosen because it serves your audience and your business. With three to five pillars, every idea has a home and every week has a shape.

What a good pillar looks like

A pillar is broader than a single post and narrower than "marketing". "Tips for first-time home buyers" is a pillar. "Real estate" is a topic. "Ten mortgage terms explained" is a post.

Good pillars are:

  • Useful to your customer, not just interesting to you.
  • Connected to what you sell, so attention leads somewhere.
  • Renewable. You can make dozens of posts in that theme without repeating yourself.
  • Distinct from each other, so your feed isn't one long sameness.

How to choose them

1. List what your customers struggle with. Pull from support tickets, sales calls, reviews and forum threads. The recurring questions are your raw material.

2. List what you know that they don't. Your expertise, data, process and behind-the-scenes.

3. Look at what already works in your niche. Note topics that get strong engagement for similar accounts, and gaps nobody covers well.

4. Group into themes. Cluster the list. Keep the clusters that combine customer need, your expertise and a link to your product.

5. Cut to three to five. More than five is hard to sustain.

A typical set

For a project-management app:

  1. Team productivity tips (education).
  2. How real teams use it (proof).
  3. Behind the scenes of building it (trust).
  4. Hot takes on how work is changing (opinion).
  5. Product updates and how-tos (product).

Notice each pillar has a job: teach, prove, build trust, provoke, inform.

Weighting

A starting split for the week:

Pillar typeShare
Educational40%
Proof and stories20%
Behind the scenes / personality20%
Opinion10%
Direct promotion10%

Adjust after you see results. If proof posts drive the most signups, give them more room.

Turning pillars into a calendar

For each pillar, brainstorm ten post ideas. Then assign pillars to days ("Mon: education, Wed: proof, Fri: opinion") and fill in ideas. This structure makes batch production simple; see building a content calendar.

Testing and revising

Every month, rank pillars by the metrics that matter: saves, shares, follows and clicks. Retire the weakest pillar or reshape it. Add a new one only when you have capacity.

Pillars across platforms

The same pillars can run everywhere; only the format changes. A "team productivity tips" pillar might become a TikTok slideshow, an X thread, an Instagram carousel and a blog post. More on that in repurposing content.

Mistakes

  • Pillars that are too broad to guide anything.
  • Pillars that only serve the business and give the audience nothing.
  • Never revisiting them.
  • Posting on a pillar because it's easy rather than because it works.
