Topic and cluster health
Find the missing prerequisite before expanding the cluster.
A cluster works when its pages answer distinct questions and connect readers to the explanations they need. Page counts and traffic cannot establish that a prerequisite exists or that a route is usable.
Begin with the cluster boundary and its present page roles.
List the parent hub, explanatory children, examples, support pages and any neighboring owner that may be confused with them. Record the current task each page performs, its intended reader, needed prerequisites, evidence and next route. Judge the present answer, rather than trust an old label in a topic map.
Check that the hub gives a useful overview and understandable routes without reproducing every specialist answer. Check children for unsupported claims, interchangeable answers, wrong scope and missing conditions. A page can remain useful while its assigned role needs correction. A useful topic with no maintained answer is a gap, not proof that a new URL is automatically needed.
Inspect the links as evidence of a real learning route.
For each required transition, record the source passage, destination URL, anchor, reason for the click and what the destination provides. Confirm that the link is present and resolves to the intended answer through the permitted review process. A line in a spreadsheet records a plan; it does not prove that a live link exists.
Trace hub-to-child, child-to-parent and any necessary prerequisite or next-step route. Check for orphaned pages, circular routes that never answer the question, misleading anchors and old destinations. Shared words alone do not justify a link. If the destination is missing, a new anchor cannot supply its explanation.
Worked diagnosis: a missing identifier prerequisite.
This fictional entity-documentation cluster has a hub, a disambiguation explanation and an advanced identity-conflict procedure. Both child pages ask the reader to “reuse the accepted entity ID”, but the cluster never explains what that ID identifies, how it differs from the page URL or where to find the accepted record.
The advanced procedure is technically detailed, yet a newcomer cannot begin it. The missing prerequisite is an identity explanation, not more troubleshooting depth. Inspect the existing introductory material before proposing a page: a clear definition and small example may fit there, with contextual links from both children. A separate maintained explanation is justified only if the task and detail need it.
| Node or route | Observed teaching condition | Decision |
|---|---|---|
| Hub | Lists both children but assumes entity-ID knowledge | Add a visible prerequisite route and explain its purpose |
| Disambiguation child | Requires an accepted ID without defining it | Link the prerequisite beside its first necessary use |
| Identity-conflict child | Starts with matching IDs; beginner lacks the input | State the prerequisite before advanced checks |
| Missing explanation | No maintained definition or example in the supplied inventory | Repair existing introduction if sufficient; otherwise approve a distinct owner |
| Growth proposal | Another advanced edge-case page is planned | Hold expansion until the prerequisite and routes are checked |
Turn the diagnosis into a small ordered repair.
First confirm the intended meaning of the identifier with the source owner. Then write the supported definition and a fictional or verified example in the accepted introductory owner. State what an identifier does not establish, such as factual accuracy or an automatic match between people with similar names. Then add the useful routes at the two places that require the input.
The acceptance test is concrete: a reader can locate the ID explanation, distinguish an entity from the page describing it, and identify the input the advanced procedure expects. Inspect the revised pages and links together. Do not mark the repair complete because a brief was written, or claim a measured improvement when no task test or live observation has been collected.
Recheck updates, ownership and overlap.
Keep the sources and dates behind definitions, product examples and policy-dependent advice. A source change can reopen other pages even if only one template changed. Compare the current hub, children and shared examples for contradictions. Mark stale or disputed claims and route them to their factual owner.
If two pages have become interchangeable, compare their tasks, audience conditions and useful evidence before consolidating them. Distinct pages can share a necessary definition without being duplicates. Preserve useful exceptions and proof when simplifying a cluster. Record the effect on links, future briefs and maintenance ownership.
Use reader feedback without turning a guess into a fact.
A comment such as “I do not know which ID this step needs” can identify a task obstacle. Record the question, page, context and permission for using the feedback; remove unnecessary personal details. Distinguish one reader’s experience from evidence about how common the issue is.
Check the reported obstacle against the page and, when appropriate, a task-based review. Support questions, internal searches and survey notes can complement source inspection, but their participants and coverage differ. A proposed journey remains a model until suitable observed evidence supports the transition. Missing feedback is not proof that everyone succeeded.
Put performance observations in their reporting context.
Search Console can show search clicks, impressions, CTR and position in selected report groupings. Keep property, page set, dates, device, country and search type with an export. Compare like conditions and preserve unavailable or preliminary states; a changed report filter can change the apparent result.
A fall in one metric does not locate the missing prerequisite or prove its cause. Demand, search appearance, query mix, indexing, seasonality and site changes can all affect observations. A strong-traffic page can still have a broken learning route. Combine performance context with answer inspection and reader evidence rather than substitute a number for the diagnosis.
Assign a health state, owner and next review.
Use a reasoned state such as usable, watch, repair, restructure or hold. Name the affected page or route, evidence, severity, dependency, accountable editor and acceptance check. Keep an evidence gap separate from a confirmed failure. The cluster may need a small link repair rather than a wholesale rewrite.
Review after meaningful content, source, template or audience changes. Record if expansion can proceed, which prerequisite blocks it and what evidence will reopen the decision. This is an editorial operating model, not a Google cluster-health score or a guarantee of ranking, traffic or reader completion.
