A website’s structure rarely remains exactly as it was planned before launch. New services, product categories, articles, landing pages, and language versions appear over time. Some sections grow faster than others, pages are moved, and certain content eventually becomes outdated. After a few years, even a well-designed website may look significantly different from its original structure.
That is why the 6 principles for optimizing website structure discussed below are primarily about improving an existing website rather than building everything from scratch. The goal is not to rebuild the entire resource. First, you need to check whether categories are still clear, whether unnecessary levels of nesting have appeared, how easy it is to find important pages, and whether the current architecture still reflects the way the business operates today.
This also matters for SEO. Search engines need to discover pages, understand the relationships between them, and identify which sections are most important. For users, the situation is simpler: they either find what they need quickly or start looking for another way to get there.
What Should You Check First?
It is useful to start website structure optimization by reviewing six areas:
-
Page grouping — is it clear why a particular page belongs to a specific section?
-
Navigation — can users find the right section without understanding the company’s internal logic?
-
Page depth and internal linking — have any important pages become practically isolated?
-
Page purpose — are several URLs targeting the same search intent?
-
Mobile version — does the structure remain convenient on a smaller screen?
-
Regular analysis — have duplicate pages, technical URLs, or unnecessary levels accumulated over time?
These six areas do not exist independently. Changing categories almost always affects navigation, internal links, and SEO, so website structure is better evaluated as a single system.
Why Does Website Structure Need to Be Optimized?
Website structure optimization helps remove unnecessary steps, make important pages easier to access, and align the site with its current content and business needs.
On a small website, structural problems may remain almost invisible for a long time. Even if a page is not exactly where it should be, users may eventually find it through the menu or search.
As the website grows, these small issues become much more noticeable. In a catalog with several thousand products, an inefficient category system may affect hundreds of pages. In a blog without clear categorization, older materials gradually become harder to discover. On a service website, new offerings are sometimes simply added to the main menu until it turns into a long, difficult-to-scan list.
At the same time, the website may still work perfectly from a technical perspective. URLs open, forms submit correctly, and Google can access the pages. The problem appears elsewhere: users increasingly struggle to understand where information is located.
Website structure optimization is therefore primarily about checking the logic of the site, not about immediately launching a redesign.
1. Group Pages According to a Clear Principle
The first principle seems obvious: content that is closely related should be located near each other. In practice, however, this is one of the areas where the most random decisions accumulate over time.
Imagine a company website that originally had three services. Several years later, it has fifteen, but all of them still sit at the same level. Some could logically be grouped into broader service areas, but the old structure remains simply because the internal team is used to it.
A new visitor does not care about the history of how the business developed. They do not know which service was launched first or which department is responsible for it. They need a clear structure that makes sense now.
How Can You Tell When Page Grouping Needs to Be Reviewed?
Try to explain the purpose of each major section in one short sentence.
For example:
Services → SEO → SEO Audit
or:
Catalog → Garden Equipment → Lawn Mowers
In these examples, it is clear why the page belongs in that location.
The situation is worse when a section contains pages simply because it was once convenient to place them together. If a category is difficult to describe in one sentence, it may have become too broad or inconsistent.
For a large website, it can be useful to draw the entire page tree without any design elements. Such a diagram quickly reveals sections that have grown disproportionately, pages that no longer have a logical place, and categories that almost duplicate one another.
Do Not Create Levels Just for the Sake of Having Levels
Hierarchy exists to help organize information, not to make the structure diagram look more sophisticated.
If a category contains only one page and serves no purpose of its own, it is worth asking whether that intermediate level is really necessary. Sometimes users have to move through several nearly empty pages simply because the site tree was originally built that way.
The opposite extreme is eliminating hierarchy entirely. When dozens of different pages are all placed at the same level, navigation becomes difficult for a different reason.
The optimal structure is not necessarily the flattest one. It is the structure in which each level helps users narrow their choices.
2. Simplify Navigation, Not Just the Page Tree
Website structure and navigation are closely related, but they are not the same thing. Structure defines how pages are organized. Navigation determines how users move between them.
A website may contain hundreds of URLs, but that does not mean every one of them should appear in the main menu.
What Should a Good Menu Look Like?
The main menu should primarily contain the sections from which users can logically begin their journey.
On a clinic website, these might be: Doctors, Services, Diagnostics, Pricing, Contacts.
On an ecommerce website: Catalog, Promotions, Shipping & Payment, Blog.
More detailed pages can then be accessed within the relevant sections.
Problems begin when the main menu is treated as a complete map of the entire website. On desktop, a large mega menu may still hide the complexity reasonably well. On a smartphone, however, users may face a long multi-level structure where it is easy to lose context.
Navigation should help people move through the site, not display the entire volume of content at once.
Breadcrumbs Are Also Part of Navigation
Breadcrumbs are especially useful on websites with deeper page hierarchies.
For example:
Home → Catalog → Footwear → Boots
Users can immediately see where they are and move one level higher without reopening the main menu.
On a small corporate website, breadcrumbs may play a secondary role. In a large catalog, blog, or knowledge base, they become much more useful.
Check Labels, Not Just Placement
Sometimes the navigation structure is technically correct, but the wording creates the problem.
A menu item such as “Solutions” may make perfect sense to the internal team while telling a new visitor almost nothing. The same may apply to labels such as “Expertise,” “Capabilities,” or “Directions.”
A good label helps users predict what they will find before they click.
That is why navigation optimization should consider not only where a menu item appears, but also whether its name is clear.
3. Control Page Depth and Internal Linking
One of the most common structural problems is an important page that has almost no natural paths leading to it.
It may be included in the sitemap, indexed by search engines, and even receive organic traffic. But if only one random internal link points to it, that page is poorly integrated into the overall website architecture.
Should Every Page Be Within Three Clicks of the Homepage?
No. There is no universal three-click rule.
For a small corporate website, many pages may naturally be accessible within that depth. For a catalog containing tens of thousands of products, requiring every URL to be the same distance from the homepage would make little sense.
It is more useful to check whether there is a clear path to the page, whether relevant internal links lead to it, and whether its depth reflects its role on the website.
For example, a company’s key service should not be buried five levels deep without a clear reason. An old archived article can naturally sit deeper within the structure.
Internal Linking Should Not Be Random
Website architecture is not limited to vertical relationships such as:
Category → Subcategory → Page
A service page may link to a relevant case study. An article may link to the service it helps explain. Two closely related articles may naturally link to one another.
This allows users to continue exploring the same topic while preventing pages from becoming isolated.
This is especially important for blogs.
When new materials regularly receive internal links while older content is ignored for years, the site gradually splits into an active section and an almost forgotten archive.
During structure optimization, it is worth revisiting older articles and checking whether they can be connected to newer content.
Look Beyond the Number of Links
One hundred internal links do not automatically make a page important.
Context matters. A link from a closely related page is usually more useful to a user than a random link from the footer or a large generic list of “related articles.”
A good internal link should answer a simple question: is the user genuinely likely to want to visit this page next?
4. Separate Pages According to Their Purpose
Content optimization begins before the text itself is written. The first step is to determine why the page exists.
For example, consider these queries:
“buy air conditioner”
and
“how to choose an air conditioner”
They refer to the same type of product, but user expectations are different.
In the first case, a product category is appropriate. In the second, an informational article makes more sense.
If both intents are forced onto a single page, the result is often overloaded: the product catalog starts looking like an article, while the informational page turns into a long sales landing page.
You Do Not Need a Separate Page for Every Keyword
The opposite problem also exists.
SEO projects sometimes create several nearly identical URLs simply because the keyword wording differs slightly.
For example:
SEO website audit
website SEO audit
professional SEO audit
comprehensive SEO audit
If search intent and the SERP are practically the same for these queries, separate pages are unlikely to be necessary.
This is where website structure optimization intersects with keyword research. The goal is not just to find keywords, but to map groups of related queries to the correct page.
What Should You Do with Duplicate or Overlapping Pages?
If two pages already exist with almost identical purposes, first determine whether they genuinely need to remain separate.
Perhaps one is aimed at a different type of customer, region, or product. If so, the distinction should be made clear.
If there is no meaningful difference, it may be better to consolidate the content and keep one stronger page.
This approach is often easier than artificially trying to separate two nearly identical pages by assigning them slightly different keywords.
