Does it matter how many clicks it takes to reach an answer page?
It matters mostly as a symptom. Pages that sit many clicks from the homepage tend to be crawled less often and recrawled more slowly, so edits take longer to register and new pages take longer to appear. A practical target is three clicks or fewer from the homepage to any answer. If your library has outgrown that, the fix is more cluster hubs, not deeper pagination.
Depth is a proxy for how important you think a page is
Nothing enforces a depth rule. What happens is that the structure of a site is read as a statement of priority: pages you link to prominently get treated as more important, and importance influences how often they are fetched and how quickly changes are noticed. Depth is the cheapest available measurement of that.
The practical consequence for an answer hub is turnaround. If you correct a fact on a page sitting six clicks deep, the corrected version may not be reflected for a long time.
Depth grows without anyone deciding it
Nobody designs a five-click structure. It appears because the library outgrew a single paginated index. Twenty answers fit on one page. Three hundred do not, and page fifteen of the index is four clicks from home before you reach the answer itself.
The cluster-hub arithmetic
The math is worth doing explicitly. If you have N answers and each hub page can reasonably list L of them, you need roughly N divided by L hubs to keep every answer at depth three: home to hub to answer.
Three hundred answers with thirty links per hub means ten cluster hubs. Six hundred answers means twenty, which is more hubs than most businesses want, so at that scale you add a second layer — a directory of clusters — and accept depth four for the long tail while keeping the commercially important answers at three. Deciding which answers get the shallow slots is a business decision, not an SEO one.
When deep is genuinely fine
Very long-tail answers that exist to be found by a specific search or quoted by an assistant do not need to be shallow. They need to be indexed, linked from somewhere relevant, and correct. Spending structural effort to promote them steals attention from the answers that sit next to a buying decision. Map depth against which questions correlate with booked work — that is what marketing intelligence is for, and it turns an architecture argument into a data one you can settle. The same logic drives how we lay out an answer hub on a new build.
