You've got 40 blog posts published and no idea which ones are actually holding your site's topical authority together — that's the moment most founders start googling "topic cluster template free" instead of just writing another post and hoping. A topic cluster template free of cost still needs to do one job well: force you to map hub pages to spokes before you write, not after you've already got a folder of orphaned articles competing with each other in Google.
Most templates you'll find online are glorified spreadsheets. Columns for keyword, search volume, status. Fine for tracking. Useless for actually deciding what belongs together. The gap isn't information — it's structure. You need something that answers "does this spoke earn its place under this hub" before it becomes 1,200 words you have to prune later.
What Is a Topic Cluster Template?
A topic cluster template is a planning document that maps one pillar topic (the hub) to a set of related subtopics (the spokes), showing how each spoke links back to the hub and to its sibling spokes. It typically includes columns for target keyword, search intent, word count target, and internal link destinations — built to be filled in before content is written, not after.
That's the theory. In practice, a template that just lists keywords in rows is barely better than a to-do list. The version that actually works has three sections, not one: the hub definition, the spoke inventory, and the link map. Skip any of the three and you'll end up with cluster content that reads like a topic cluster but doesn't function like one — no shared linking, no clear hierarchy, and Google treating each page as its own island.
How to Build a Topic Cluster Template (Step-by-Step)
Here's the sequence that produces a cluster structure you can actually execute, not just admire in a spreadsheet:
- Pick one hub topic broad enough to support 8-15 spokes but narrow enough that a single page could plausibly rank for it.
- List every subtopic a reader researching the hub would need answered, pulling from "People Also Ask," competitor headings, and your own support tickets.
- Assign one primary keyword per spoke — never let two spokes target the same keyword, or you'll cannibalize your own rankings.
- Tag each spoke's search intent (informational, comparison, transactional) so you know what format it needs.
- Set a word count range per spoke based on what's currently ranking for that keyword, not a fixed number for the whole cluster.
- Map the link direction: every spoke links up to the hub, the hub links down to every spoke, and adjacent spokes link sideways to each other.
- Sequence publishing so the hub goes live first or within days of the first two spokes — an empty hub with no spokes linking to it signals nothing to Google.
- Set a review date, 90 days out, to check which spokes are underperforming and need a rewrite or a merge.
That link-mapping step is where almost everyone underbuilds. A spreadsheet with keyword columns tells you what to write. It says nothing about how pages should connect once they're live, and connection is the entire point of a cluster. A hub with twelve unlinked spokes isn't a topic cluster. It's twelve blog posts that happen to share a theme.
The Mistake That Breaks Most Topic Clusters
Founders build the spoke list first and the hub second. That's backwards, and it's why so many clusters feel bolted together instead of designed. If you start with "here are twelve keywords I want to rank for" and only afterward ask "what should the hub page be," you end up retrofitting a pillar page around content that was never written to support one. The hub reads like a summary nobody asked for, spokes reference concepts the hub never actually introduces, and the internal linking feels forced because it is forced.
Do it the other way. Define the hub's promise first — the one page that, on its own, could satisfy someone who wants the complete picture. Then build spokes as the deep-dive answers to questions the hub can only gesture at. A hub page on "email deliverability" that mentions SPF and DKIM in a sentence each is doing its job correctly if two of your spokes go deep on exactly those. The hub stays skimmable. The spokes carry the weight.
The second mistake, less obvious but just as damaging: treating the template as a one-time planning exercise instead of a living map. Search intent shifts. A spoke you wrote as informational six months ago might now be facing comparison-heavy SERPs because three competitors launched "X vs Y" pages. If your template lives in a drawer, you won't catch that. If it's something you revisit quarterly against your Search Console data, you will.
Free Template Structure: What to Include
The table below is the actual structure, copy it into a spreadsheet or a Notion table, whichever you'll actually maintain:
| Field | Purpose | Example |
|---|---|---|
| Hub topic | The single page every spoke supports | "SEO for Shopify stores" |
| Spoke keyword | One unique keyword per row | "Shopify collection page SEO" |
| Search intent | Informational, comparison, transactional | Informational |
| Target word count | Based on current top-10 average, not a fixed rule | 1,400 |
| Links to | Which other spokes this page should reference | 2 sibling spokes + hub |
| Status | Drafted, published, needs update | Published |
| Last reviewed | Date of last performance check | 2026-03-01 |
Seven fields. That's enough. Add more and you'll spend longer maintaining the template than executing the cluster, a trap a lot of "comprehensive" templates fall into by trying to track everything from author assignment to social promotion in the same sheet. Keep those elsewhere.
Topic Cluster Template vs. Content Calendar: Why They're Not the Same Thing
This is the gap most guides on this topic skip entirely, and it's the one that actually trips people up. A content calendar answers "what gets published when." A topic cluster template answers "how does this piece relate structurally to everything else." Founders conflate the two constantly, and the result is a calendar full of scheduled posts with no cluster logic underneath them — publishing cadence without publishing architecture.
Here's the practical difference: your calendar can tell you that a post goes live on the 14th. It cannot tell you whether that post should link to three existing spokes, whether it cannibalizes a page you published in January, or whether the hub it's supposed to support even exists yet. A calendar is a scheduling tool. A cluster template is a relationship map. You need both, but they're not interchangeable, and trying to force cluster logic into a calendar tool is like trying to plan a family tree in a to-do list app — the fields just aren't built for it.
If you're running both, the calendar should be downstream of the template, not the other way around. Decide the cluster structure first. Let the calendar schedule execution of a plan that already exists, rather than using the calendar to improvise a plan as you go.
Where a Spreadsheet Template Hits Its Limit
A spreadsheet works fine for your first cluster. It falls apart at your third. By then you're tracking keyword overlap across clusters by memory, manually checking whether "email deliverability checklist" you wrote in cluster two is quietly competing with "email deliverability guide" in cluster four. Nobody catches that until Search Console shows both pages splitting clicks for the same query.
This is where cannibalization detection stops being optional. A manually maintained template has no way to flag that two spokes across different clusters are fighting for the same SERP. It's not built to. It's a static document, and cannibalization is a dynamic problem — new pages create new overlaps every time you publish. We built the topic cluster tool in WriteGap specifically because the spreadsheet approach has a ceiling: it plans clusters fine but can't monitor them once they're live, can't flag when a spoke starts stealing rankings from its own hub, and can't tell you which spoke is quietly underperforming three months after launch.
The other limit is keyword sourcing. A blank template assumes you already know your spokes. Most founders don't — they know their hub topic and then guess at subtopics based on what feels comprehensive. WriteGap's competitor keyword research surfaces the actual queries competitors rank for around your hub topic, which turns "what should my spokes be" from a brainstorm into a data pull. Once you've got that list, the SEO content brief generator turns each spoke keyword into a brief with intent, target length, and subheadings — the exact fields your template needs, filled in automatically instead of guessed at.
Should You Build the Hub Page or the Spokes First?
Build the hub first, but don't publish it first. Draft the hub page completely — headline, structure, the full argument — so you know exactly what gaps it deliberately leaves open. Then write two or three spokes that fill those gaps, and publish the hub within the same week as the first spokes. A hub sitting alone with zero internal links pointing into it from spokes looks incomplete to both readers and Google, and an empty hub often ranks worse than no hub at all because it reads as thin content with nothing backing it up.
The founders who get this wrong publish the hub in January, tell themselves they'll "get to the spokes eventually," and by June the hub still stands alone, ranking for nothing in particular, disconnected from the six unrelated posts they published in the meantime. Sequence matters as much as structure.

Pick one topic your product genuinely owns, list the eight questions a buyer would ask around it, and put them into the seven-field structure above before you write a single spoke. If you want the spoke list and the keyword data pulled for you instead of guessed at, run that hub topic through WriteGap's topic cluster planner and let the keyword gap analysis surface the subtopics your competitors are already ranking for, the ones your cluster needs to beat.
