TL;DR

Ask the contributor to show where the answer changes. Give each distinct customer decision a source, an owner and a page. Refresh an existing guide when it already serves that reader. Commission a separate walkthrough when the evidence and the next action differ, then test it with someone who missed the briefing.

Ask someone who delivers your service to show you a decision a customer has to make. If they bring a sample, a marked-up drawing or a form with one particularly troublesome box, lovely. You have somewhere to start.

Now ask what the customer can do with that evidence. That answer will tell you whether you have the makings of a new article, a useful addition to an existing page or a question for the next meeting. All three are perfectly respectable outcomes.

An article cluster is a set of related explanations a reader can move between. Its home is a blog category aligned with a primary service or product collection. To build one, bring the service page, the articles already in that category, a contributor who knows the work and one example you have permission to discuss. A half-hour with those materials can produce a better brief than an afternoon spent inventing titles.

## Ask the expert to show you where the answer changes

Suppose you run a fictional fitted-furniture business. Your designer suggests an article about choosing cabinet finishes. Before anyone opens a blank document, lay a finish sample and the sample approval form on the table. Ask the designer to walk through one choice from the customer's side.

Try three questions. What can the customer tell from this sample? What still needs confirming? What would change your advice? The third question earns its keep. If the designer gives different instructions before and after the customer signs off a sample, you may have two distinct reader tasks hiding under one rather broad title.

Write down what the contributor showed you, which claim it supports, any exceptions and who can approve the public wording. A photograph can show two samples side by side. It cannot establish your current approval policy. For that, fetch the current form and ask its owner to check the wording. Keep private examples in your working notes and agree what can be shown publicly. Google's [guide to helpful content](https://developers.google.com/search/docs/fundamentals/creating-helpful-content) asks publishers to consider first-hand expertise and what a reader can learn beyond the obvious.

## Give each question an address

In our client work, our team built separate service pages for distinct types of work. That gives you a useful starting point when planning the supporting articles. Open the page where someone can actually enquire about the service. Keep the scope of the offer there. Use the articles for questions that deserve a fuller explanation, then link the reader back to the service when they are ready.

Here is how that might work for our imaginary furniture business. The questions, documents and decisions below are illustrative. Your own service terms need someone at your business to confirm them.

| Customer question | Evidence to inspect | Where the answer belongs |
| --- | --- | --- |
| Can I order fitted cabinets for this room? | Current service scope and enquiry requirements | Keep this on the fitted-furniture service page. The reader wants to check the offer. |
| How do I compare two finish samples at home? | Two authorised samples and the designer's comparison notes | Refresh the existing finishes guide. Add a side-by-side demonstration and explain what the sample leaves undecided. |
| What exactly am I approving when I sign off a sample? | Current approval form and an authorised, blank example | Commission a guide in the fitted-furniture category if the archive has no walkthrough. End with the questions to resolve before signing. |
| Which cabinet finish should I pick? | Same samples, same decision as the comparison guide | Add this wording to the existing brief. A second URL would give the editor two copies of the same job. |

Our [content hub guide](https://www.zincdigital.co/blog/build-a-content-hub-people-can-use/) covers the category and its navigation. Here, the editorial work is deciding which question belongs on which page. A category can house several articles without promising a fresh one for every variation of a question.

## Make a writer's brief from one row

Take the sign-off question. Give the writer a reader, a source, a boundary and a finish line. For example:

A customer has chosen a finish and received the sample approval form. Using the current blank form, show them where to identify the sample, which details the form asks them to confirm and whom to contact about a discrepancy. Ask the form owner to verify each field. Leave sample comparisons in the finishes guide. The reader should be able to point to what they are approving and identify anything they still need to ask.

That is a brief someone can test. Hand the draft and the blank form to a colleague who missed the meeting. Ask them to locate the sample reference and explain what they would do if it differed from the sample in front of them. If they need the designer to translate the article, you have found the paragraph to fix. The [content brief walkthrough](https://www.zincdigital.co/blog/content-briefs-search-intent-internal-links/) has a fuller handover template.

Link the comparison guide to the approval walkthrough at the point where the customer has chosen a sample. In the walkthrough, give anyone still deciding a route back to the comparison. Use link wording that names the task, such as “compare your finish samples”. Google's [link guidance](https://developers.google.com/search/docs/crawling-indexing/links-crawlable) explains how descriptive link text helps readers and search systems understand a destination.

## Check whether two pages are trying to do the same job

Editors sometimes call this cannibalisation. A practical test is to cover the titles and read each page's opening, example and final action. If you could swap all three and the reader would barely notice, keep one brief and improve the page that already answers the question. If the examples and actions differ, make that distinction visible near the top of each page.

If you have Search Console access, open the Search results performance report. Select a date range, filter to a relevant query and open Pages. Inspect the actual pages that appeared. In our example, appearances for both the service page and the comparison guide under a broad cabinet query could make sense. For a question about sample approval, check whether the page people reach actually explains sign-off. Google's [Performance report documentation](https://support.google.com/webmasters/answer/7576553) explains its filters and the limits on the queries shown. Shared appearances alone cannot tell you that two pages are costing each other traffic.

Record the question, the two URLs, what each reader can do and the decision you made. Without search data, do the same editorial comparison and leave the search observation pending. You can still fix a confusing pair of introductions today.

## Take one assignment out of the meeting

[Download the article cluster worksheet (CSV)](https://www.zincdigital.co/downloads/expertise-article-cluster.csv) and open it in your spreadsheet app. The fictional rows show how the same topic can lead to a refresh, a new guide or a decision to combine two ideas. Keep them for reference. Duplicate the blank row for each real customer question, name the evidence owner and record the URL you inspected before assigning a writer.

After publication, start at the category on a phone. Can a colleague choose the right article, use its example and reach the next relevant page? Ask the contributor to check the live explanation against the approved evidence. Put any correction beside the row that prompted it. If your team wants help investigating overlapping search results, our [SEO service](https://www.zincdigital.co/services/seo/) covers that work. You can also find the related guides in our [SEO article category](https://www.zincdigital.co/blog/category/seo/).

One question with a clear home and a checked answer is enough to start. The second article earns its place when it helps the reader do something different.
