Website Structure for SEO: How to Design Sections Correctly
Site structure isn't menu design — it's the map crawlers and users follow to find pages. A poor structure kills a campaign before content work even starts: pages simply don't get found or indexed.
The three-click rule, and why it's half outdated
The old rule said any page should be reachable within three clicks from the homepage. It hasn't lost all meaning, but what matters more is depth in terms of crawl budget logic: a page reached only through a long chain of links, without a direct internal path, gets crawled less often and ranks worse as a result.
A practical benchmark for a mid-size service site or online store is no more than four levels of nesting: homepage → category → subcategory → item page. Large catalogs with thousands of products add filters and hub pages, but the principle holds — every target page needs a direct link from at least one higher-level page.
Checking actual depth is easy in Screaming Frog: the Crawl Depth column shows how many hops the crawler took to reach a page. Anything past five levels is a candidate for restructuring.
Flat structure vs. nested categories
A flat structure — where most pages sit directly one level below the homepage — works well for sites with a small service range: a studio, a clinic, a law firm. Users and crawlers see the full range at once, and link equity from the homepage spreads to every key page without loss.
A nested structure is needed where volume demands navigational logic: a store with 500+ products, a knowledge base, a service catalog split by region. Here categories and subcategories act as hubs — they collect internal links to item pages and rank themselves for mid-frequency queries like 'buy an air conditioner in Tashkent'.
A common mistake is mixing both approaches without logic — some sections flat, others buried four levels deep for no reason. Before designing structure, list every target page and its target queries, then group by topical closeness rather than by what was convenient to build in the menu.
Internal linking as a tool, not decoration
Internal links pass page equity (what used to be called PageRank flow) and build topical clusters — a signal to Google that a group of pages fully covers one subject. Every new blog post should link to at least one commercial page and receive a link back from the relevant catalog section — not as a formality, but as a way to route equity to the pages that make money.
Anchor text matters: a link that says 'read more' conveys nothing to a user or a crawler. Use natural anchors that include the target page's key phrase, but don't overdo it — if the whole site links to a product page with the words 'buy cheap air conditioner', that reads as manipulation and can be treated as a spam signal.
Breadcrumbs marked up with schema.org's BreadcrumbList deliver a double benefit: users understand where they are, and Google gets an explicit section hierarchy for the search snippet.
URLs are part of structure, not cosmetics
A URL should reflect hierarchy: site.uz/services/apartment-renovation/ reads better for both humans and crawlers than site.uz/page?id=482. Every path segment is an extra relevance signal and, at the same time, a navigational hint in the search snippet.
Don't overdo length: a URL longer than 4-5 segments breaks readability and usually signals the category structure is too deep. If you end up with site.uz/catalog/appliances/climate/air-conditioners/split-systems/, merge the last two levels.
When restructuring, 301 redirects from old URLs to new ones are mandatory — without them you lose accumulated page equity and rankings. Check redirects in bulk after migration through the 'Page indexing' report in Google Search Console, not from memory.
Hub pages and topic clusters
A hub is an overview page that links to all child materials and itself covers a broad query: 'SEO services' as a hub for 'ecommerce SEO', 'SEO audit', 'local SEO'. This is called the cluster content model, and by Google's own guidance it performs better for complex topics than scattered, unlinked articles.
For a service site, hub pages usually correspond to the main sections of the service catalog; for a blog, to major topical categories. The core rule: every child page links to the hub, and the hub links to every child — a two-way link reinforces the topical signal far more than a one-way one.
