A pillar is a promise, not a topic
A topic is what one post is about. A pillar is what people can count on you for, week after week. Think of the friend who always knows the good restaurant.
You keep asking because of the pattern, not because of one dinner. To keep each pillar fed, get the free 7-day posting routine.
How many content pillars should you have?
Start with three. Most guides say three to five, and that range is fine. The number matters less than giving each pillar a job.
On the accounts I run for my app Endii, we split pillars by job. Reach pillars are built to travel to strangers.
Conversation pillars are built to get replies from people who already follow.
We made that split after reading 192 comments.
Then we moved the conversation themes, like day-by-day recovery, fatigue and beginner explainers, onto the diary-style accounts.
The reach themes stayed on the education accounts.
What happens when one pillar wins?
It eats the others. Our best Spanish hook, about what you get asked before surgery, averaged 57,700 views. That was three to eight times everything else.
So the system made more surgery posts. Then more. By September, the Spanish and French pools were all “things nobody tells you” surgery lists.
Then we read what people were actually saying. In real comments on Reddit and TikTok, 48% were about medication, bowels and exercise.
Out of 72 posts, zero covered them. The audience had told us their pillars. We were busy repeating our hit.
There was a quieter cost. The surgery content sold a surgery companion, and the app isn’t one yet.
Views that promise something your product doesn’t do are borrowed.
We added 34 new hooks on the missing topics, in the shapes that were already winning.
Now I look for pillars in comments first, and in last month’s best post second.
“Here are 50 comments from people in my niche. Group them into themes.
For each theme, count how many comments mention it and how many of my last 30 posts cover it.
Show the biggest gaps first. Only use themes that appear in the comments.”
Is a content pillar the same as a pillar page?
No. In SEO, a pillar page is one long page on a broad topic that links out to shorter pages on related questions.
A content pillar on social is a theme that runs across many posts.
They can line up, and a strong pillar page can anchor one of your social themes. But if someone says “pillar” in a meeting, ask which one they mean.
When pillars matter, and when they don’t
They matter when you post often, and most of all when AI generates posts for you. Without pillars, a system drifts toward whatever worked last.
They matter less when you post once a week about real client work. The work is already the pillar.
Skip them for your first couple of weeks. Find out what people respond to before you build a structure around it.
Next: how a social media hook carries a pillar into the feed, and how content repurposing keeps one supplied.
