How to optimise click depth

Click depth is the number of clicks someone needs to get from your homepage to a specific page. The short answer: the deeper a page is buried, the less important Google considers it, the slower it gets crawled and indexed, and the lower it ranks. For a B2B site that runs on enquiries, that is a problem you solve in the architecture, not with more content. In this article you will read how to measure click depth and enforce a flat structure.

What is click depth and why does Google treat it as a signal?

Click depth (also called crawl depth) counts the shortest click distance from your starting point, usually the homepage, to a page. A page you reach directly from the main menu sits at depth one. If you first have to go to a category, then to a subcategory and only then to the article, that page sits at depth three or four.

For search engines, that distance is not a coincidence but information. The pages you place high in your structure and link to from many places are the ones you treat as important yourself. Google infers that they deserve priority. It is a part of SEO that stands apart from your copy or your backlinks: it is purely about how your site is built. If you want the wider frame, first read our explanation of what SEO is, which click depth plugs into as a technical building block.

The logic is the same one a crawler follows. A bot starts on a known URL, follows the links it finds, and works its way deeper and deeper. The further a page sits from the starting point, the later the bot arrives, and the less often it comes back to check whether anything has changed.

Why deep pages lose ranking potential

The problem with pages buried deep is not only that they look less important. It is that in practice they get crawled less often, or not at all. And a page that is not crawled cannot be indexed. And a page that is not in the index ranks for nothing.

For large sites, crawl budget plays a role here: the number of pages Google is willing to fetch on your domain within a given period. Bury your valuable service pages four or five clicks deep and you burn that budget on intermediate layers before the bot reaches what matters. On smaller B2B sites, crawl budget is rarely the bottleneck, but the signal of depth still counts: a page at depth six is simply taken less seriously than the same page at depth two.

You see this reflected in your crawl stats in Search Console. Pages that are rarely or never crawled are almost always too deep or receive too few internal links. That is not a technical detail to tick off in an audit, it is lost traffic. Every commercial page Google leaves behind is a leak in your acquisition layer.

How do you measure the click depth of your site?

Before you enforce anything, you need to know where you stand. Click depth is not measured on gut feeling, but with a crawl.

• Run a crawl with a tool such as Screaming Frog. It reports the crawl depth per URL, in other words the shortest click distance from your starting page. Sort on that column and you immediately see which pages sit too deep.
• Filter on your money pages. This is not about every blog post. It is about your service pages, your most important category and solution pages and your strongest content. If those sit at depth four or deeper, you have work to do.
• Compare with your internal links. A page at depth two that receives only one internal link is still weakly positioned. Depth and internal link count often move together, but not always.
• Cross-reference with your analytics. Pages that sit deep and pull in little traffic are your first priority to lift up.

The goal of this measurement is not a perfect map. It is a list of pages that sit too far from your homepage and that you consider commercially important. That list is your work plan.

Enforcing a flat architecture: the concrete interventions

A flat structure means that every page that matters is reachable in three to four clicks at most. That is not a law, but a workable principle. Here is how you enforce it.

Start with your main navigation. Your menu is the most powerful instrument for reducing depth, because everything you include in it lands at depth one for your entire site at once. Put your most important services and categories there, not your about page or your job openings.

Build hub pages. A hub, or pillar page, gathers related content and links to it. Our website architecture for SEO shows how topic clusters group your content. A good hub lifts ten deep articles up in one go, because they all end up one click away from that hub.

Add targeted internal links. From your strong, shallow pages you link to the pages you want to lift. That not only shortens the click distance, it also distributes authority. Do this with descriptive anchor text, not a vague “read more”.

Prune what does not need to exist. Every redundant intermediate layer or thin page pushes the rest deeper. Fewer, stronger pages almost always deliver a flatter and better performing site.

Watch your pagination and filters. Webshops and large catalogues unknowingly create enormous depth through filter pages and endless page numbers. Make sure important products or items are not reachable only via page seven of a filter.

If you would rather not untangle this yourself, our SEO specialist programmes pick up exactly this: we crawl your site, expose the deep pages and restructure your internal links around the pages that produce pipeline.

Click depth is a pipeline issue, not a technical trick

It is tempting to see click depth as a technical checkbox: run a crawl, move a few links, done. But the reason it works is commercial. Every page you bring closer to your homepage gets a better chance of being crawled, indexed and ranked. And the pages you want to lift are precisely your service and solution pages, the pages where a visitor submits an enquiry.

That is why we never treat architecture separately from the rest. For us, SEO is the acquisition layer of a single steered growth engine, optimised for pipeline and not for visitor numbers that look good in a report. A flat site that guides visitors and bots smoothly to your commercial pages does both at once: it ranks better and it turns more traffic into conversations. And because AI search engines such as ChatGPT and Perplexity find and cite those same well-structured pages more easily, a flat architecture works for your visibility there too.
