Welcome to the Leaders Insights Podcast.

Today's episode, Building Topic Clusters and Pillar Content, a CMO's execution playbook.

Most B2B blogs are content graveyards.

Dozens of articles and Google ignores every one of them.

Why?

Because they're orphans.

Someone wrote 40 posts because 40 keywords look juicy and none of them talk to each

other.

Google reads that as,

This company knows a little about everything and nothing about anything.

That sounds like an excuse for lazy writers.

No, it's an architecture problem.

The old lesson, and the smart operators internalized this years ago, is that authority isn't a

per-article thing.

It's a per-topic thing.

You don't rank because one page is brilliant.

You rank because your whole neighborhood of pages says, we own this subject.

Neighborhood.

Unpack that.

It's called a topic cluster.

You write one big pillar page, the definitive guide to say, warehouse automation, then eight

or ten smaller pieces around it.

Robotics, labor cost, ROI models.

Every small piece links up to the pillar.

The pillar links back down.

Google crawls that web and thinks, these people are serious.

So it's internal linking with a fancy name?

Partly, yes, and I won't pretend otherwise.

But the discipline is what's rare.

Most teams link randomly.

A cluster means every article has a job and a hierarchy.

HubSpot, and they sell software that does this, so grain of salt, ran the experiment on their

own blog back in the day and found that the more interlinked a cluster got, the higher

the whole thing climbed.

Not one page, the whole cluster.

Give me a real number, not a vendor fairy tale.

Fair.

I ran this at a logistics software company.

We had 90 articles, average position 30-something, meaning page three of Google, where clicks

go to die.

We killed 40 of them, merged the survivors into six clusters.

Nine months later, three pillars sat in the top five for their main terms, and organic

traffic to those clusters roughly tripled.

We wrote fewer articles that year, not more.

You deleted 40 articles.

Someone got fired for writing those.

Someone should have been fired for commissioning them with no plan.

Printing content feels like burning money, but a thin page actively drags your domain

down.

It dilutes what Google thinks you're about.

Pruning is half the job.

Okay, but everyone now knows the word pillar.

You know, so why do most still fail?

Because they build the cluster around what they want to sell instead of around how a

buyer actually searches.

They write why our product is great and call it a pillar.

Nobody Googles that.

The durable principle is, the cluster maps to a question the market is already asking.

In the market's words, not yours.

How do you find those words without guessing?

Look at the questions your sales team answers in every call.

Those are your subtopics, pre-validated.

Then check the people also ask box in Google.

That little accordion of related questions.

It's a free map of the cluster.

I've never needed an expensive tool to start.

The intelligence is sitting in your own call recordings.

Isn't this whole model wobble now that people ask AI chatbots instead of typing into Google?

It actually holds up better.

The language models that power those chatbots pull from sources they judge authoritative

on a topic.

Guess what signals authority on a topic?

A dense, interlinked cluster.

Scattered orphan pages don't get cited by an AI answer any more than they rank.

If anything, being the definitive voice on one subject matters more now, not less.

So the graveyard blogs get worse and the clustered ones get cited.

Exactly.

The gap widens.

The companies who did the boring architectural work in 2023 are the ones showing up inside

AI answers in 2026.

Everyone else is invisible twice over.

Give me the one thing to do Monday morning.

Open your blog, export every URL, and sort them by which topic they serve.

You'll find three or four real themes and a pile of orphans serving nothing.

Pick your strongest theme, name the pillar, and link every relevant article up to it.

One afternoon.

That's your first cluster.

And it costs you nothing but honesty about what you've already got.

That's a wrap.
