Build supplementary linking paths that give both Googlebot and users shorter routes to deep revenue pages, without touching the URL structure or the primary navigation at all. Click depth and URL hierarchy are two different things measured two different ways, and conflating them is what causes teams to think flattening URLs is required to fix a click-depth problem. Click depth is the number of link-clicks needed to reach a page from an entry point (usually the homepage); URL hierarchy is the logical folder path encoded in the URL string itself (/category/subcategory/product). You can have a URL four folders deep that’s reachable in two clicks, and a URL with a flat, single-segment path that takes six clicks to reach if nothing links to it directly. Fixing click depth means adding link paths, not renaming or restructuring URLs.
The mechanism: why URL structure and click depth are separate problems
A URL’s folder depth is just a string pattern. It tells a crawler nothing about how many links it has to traverse to discover that URL; it’s purely organizational and can matter for human readability, categorization logic, and sometimes for signaling topical grouping, but Google has repeatedly said URL structure itself is a minor factor and folder depth in particular is not treated as a crawl or ranking obstacle on its own.
Click depth, by contrast, is a function of the actual link graph, how many “hops” a crawler or user must take through tags to arrive at the page, starting from wherever the crawl or session begins. This matters because Google’s guidance on large sites and crawl budget links crawl frequency and prioritization to how easily and how often a URL is discovered through links; pages that are many clicks deep from the entry points a crawler favors (homepage, top category pages, sitemap-listed URLs) tend to get crawled less frequently and get less link equity flowing to them internally, since PageRank-style link equity distribution attenuates with each additional hop from a strongly-linked source.
The reason large e-commerce sites end up with deep click paths isn’t usually the URL structure, it’s that revenue pages (individual product pages, deep SKU variants, or niche category pages several levels into a taxonomy) often only get linked to from one place: the parent category listing page they belong to, paginated deep into page 8 or 12 of a category grid. If a product only appears on page 12 of a category’s pagination and nowhere else on the site, its click depth is high (homepage to top category to subcategory to page-12-of-pagination to product) regardless of how short or long its URL is.
The strategy: add paths, don’t remove structure
Contextual in-content links. Editorial or informational content (buying guides, comparison pages, blog-style category overviews) that already exists or gets built for SEO/content-marketing purposes is a natural place to link directly to specific deep product or subcategory pages. This creates a second, shorter path to the page that doesn’t depend on pagination depth in the primary category browse structure.
Curated modules on high-traffic pages. “Popular in this category,” “related products,” “frequently bought together,” or “trending now” modules placed on high-authority pages (homepage, top-level category pages, high-traffic seasonal landing pages) create direct links to deeper revenue pages from pages that are themselves only one or two clicks from the homepage. This is one of the most effective levers because it deliberately borrows link equity and crawl attention from your strongest pages and redirects some of it several levels deeper without any change to the taxonomy.
Breadcrumb and mega-menu shortcuts. Expanding mega-menus to include direct links to specific high-value subcategories (not just top-level categories) reduces the click path for those specific destinations without adding depth to the URL or restructuring the site’s information architecture. This works because mega-menus render on every page and are typically crawled and followed consistently, making them one of the highest-leverage places to shorten paths to a curated list of priority pages.
XML sitemap completeness and freshness. While sitemaps don’t reduce click depth in the link-graph sense (a sitemap entry isn’t a clicked link), they do independently support discovery and re-crawling of deep URLs, which is part of why Google’s documentation on sitemaps recommends including canonical, indexable URLs, especially on large sites where not every page is easily discoverable through crawling alone. This is a complementary tactic, addressing the discovery half of the problem while the linking strategies above address both discovery and link-equity flow.
Faceted/filtered navigation with crawlable links (used carefully). Adding filter or attribute-based navigation that generates crawlable links to specific product subsets (by brand, price band, or use case) can create additional short paths into deep inventory, provided this doesn’t reintroduce the parameter-URL bloat problem covered elsewhere; the fix is to make sure any such filtered views that are valuable enough to want indexed have clean, canonical URLs and are linked to consistently, not accidentally spun up as infinite crawlable combinations.
What to avoid
Don’t respond to a click-depth audit finding by proposing to cut folder levels out of the URL structure. Renaming /category/subcategory/product-name to /product-name doesn’t change how many links away the page is; it only risks breaking existing backlinks, historical rankings tied to the URL, and any topical signal the folder structure was providing, all for a change that doesn’t touch the actual mechanism (the link graph) that determines click depth. Similarly, don’t solve this by cramming dozens of new links into the main navigation itself; overloading a global nav with links meant for a small subset of high-priority pages dilutes the nav’s usability for the majority of visitors and dilutes the per-link equity value distributed through it, since equity passed through a page’s outbound links is split across all of them. The supplementary-path approach (contextual links, curated modules, expanded but scoped mega-menu sections, sitemap completeness) achieves the same crawl and equity benefits while keeping the primary navigation focused and the URL hierarchy, and any SEO value or backlinks tied to it, intact.
A worked example of click depth versus URL depth
Suppose a mid-size e-commerce site sells a specific cordless drill at the URL /power-tools/cordless/drills/brand-x-18v-drill, four folders deep. That product only appears linked from page 9 of its subcategory’s paginated grid, so reaching it from the homepage takes five clicks: homepage to power tools category, to cordless subcategory, to page 9 of the listing, to the product itself. Now suppose the team adds a “best cordless drills under $150” buying guide linked from the homepage, with a direct link to that same drill partway down the guide. The URL doesn’t change at all, it’s still four folders deep, but the click depth drops to two: homepage to buying guide to product. Crawl frequency and internal link equity to that product page respond to the two-click path now available, even though the string “/power-tools/cordless/drills/” never moved. Flattening the URL to /brand-x-18v-drill would have changed nothing about the click path and would have broken any existing backlinks pointing to the original address.
