Pillar posts get treated like trophies. Long, comprehensive, exhaustive — as if word count alone proved authority.

It doesn't.

A pillar post earns its length by doing a specific job inside your content architecture. If you can't say what that job is before you start writing, the piece will sprawl, the research will drift, and the finished article will sit on your site collecting nothing but dust.

If you're still deciding whether a topic deserves a long-form piece at all, start with our guide to long-form content. This one assumes you've decided, so let's walk through what it actually takes to build one, from the first research session to the day you start measuring whether it worked.

Where Pillar Content Fits

A pillar post is the top of a hub-and-spoke. It covers a core subject from an educational, top-level perspective, and the spokes — your supporting blog posts — fan out from it into narrower, more specific terms.

You're writing for early-stage awareness. Someone has a question. They search. They land on a piece that answers almost every reasonable version of that question and points them deeper into your site from there.

That's the job. Hub at the top, spokes underneath, and the pillar doing the connective work between them.

People get tangled up on terminology. Pillar post, pillar page, cornerstone content, hub content — these are mostly synonyms. The one distinction worth keeping is between a pillar page and a pillar blog post. A pillar page sits further down the funnel and behaves more like a landing page: heavier on conversion, lighter on prose. A pillar blog is the library — the place a reader goes when they want the full picture on a subject.

You need to know which one you're writing before you write a word.

Pre-Draft Research

The research phase is where most pillar posts are quietly won or lost.

Look at who's already ranking. Read the top results for your target term. Not skim — read. You're trying to find the questions everyone covers, the angles nobody covers, and the depth your piece needs to hit to be in the conversation at all.

Use those results to benchmark coverage, not length. List the questions every top result answers, the subtopics they go deep on, and the ones they skip. That list is what "comprehensive" means for this topic. The length follows from covering it well, and padding a draft to match a competitor's word count adds nothing a reader needs.

Then look at the keyword itself and the variants around it. A small change to a search term can shift the intent from awareness to consideration. "What is X" and "best X for Y" are not the same query, and they don't belong in the same piece.

This is also where Siteimprove.ai helps. Topic Research shows the related topics, entities and variants that define your subject, so you can build them into the outline before you start drafting instead of finding the gaps after.

Brief and Outline, With Collaboration Built In

Once you know what you're writing and what it needs to cover, draft an outline of 10 to 15 elements — headings, subheadings, callouts — that break the piece into sections a reader can actually navigate.

Then run it past your stakeholder.

This is the step that saves pillar posts. Get the outline approved before the writer drafts. If a section is going to get cut, you want it cut now, not after 1,200 words have been written around it.

A content brief should give the writer a framework, not a cage. I tend to structure each section with a Key Points block — the claims and facts that need to be in there — and then leave the writer room to actually write. Briefs that script every sentence produce articles that read like they were assembled from a kit. Briefs that name the destination and trust the writer to get there produce articles people read.

Drafting With Subject Matter Experts

Pillar posts that sound like every other pillar post on the topic have one thing in common: nobody with original knowledge was involved in writing them.

Fix that early. Find a subject matter expert — inside your company, inside your client's company, in your network — and book 30 minutes. Record it. Transcribe it. The quotes, framings, and offhand observations from that conversation are the parts of your finished piece that no competitor can replicate.

If you finish your draft and can't circle a single sentence that no other company could have written, you've produced derivative content.

That's the test.

Then write the piece like you'd want someone to read it. Build in an internal revisions pass before anything goes to the client — voice, tone, and style should be settled before external eyes are on the draft.

Design and Web Dev Considerations

A pillar post is not a wall of text with three subheadings. If you're treating it like one, your readers are bouncing. (For layout patterns that work, see our guide to pillar page design.)

While you're outlining, start making notes about how each section wants to look. Callout boxes. Pull quotes. Inline graphics. A table of contents that actually works. A custom hero. Anything that breaks up the page and gives a reader landmarks.

Marry the new design elements with what already exists in your component library. Designers and developers will move faster when you bring them into the conversation with concrete ideas, not a finished draft and a request to "make it look nice."

Then read the finished page on a phone. If you'd click off, your readers will too.

Measuring Results

Pillar performance is the question everyone wants a clean answer to, and there isn't one.

Different metrics mean different things to different people. Traffic matters to some, conversion to others, assisted revenue to the people who hold the budget. So pick the metrics that mean something to the audience you're reporting to, and tell that story consistently.

Watch the page in context, not in isolation. Are other pages on the same topic outperforming the pillar? That's a signal — maybe the pillar needs a link from the page that's pulling traffic, or maybe the pillar's intent is mismatched to the search. Look at search features, gated assets, and the paths readers take from the pillar into the rest of your site.

Then add answer engines to the list. AI answers tend to cite a long page section by section rather than as a whole, so alongside traffic and conversions, check whether your pillar's sections are being cited for the questions they answer. A section that never gets cited may need a clearer heading or a more direct answer up top.

A pillar that ranks but doesn't move anyone deeper into your content isn't doing its job.

Interlinking

Two to three internal links inside the first 200 to 300 words. Educational, not salesy. Lead the reader somewhere useful, not somewhere you're trying to sell them.

The point of a pillar is to be the start of a journey through your content, not the end of one.

Build the spokes. Link to them. Then go back to the pillar every quarter and add the new ones.

That's the work. Most of it is unglamorous, and almost all of it happens before anyone starts writing.
