Site architecture: Creating a website structure that ranks (original) (raw)

Your website architecture directly impacts usability and SEO success.

A clear, logical structure helps users find what they need faster and signals to search engines what your site is about. Done right, it reinforces topical authority, supports long-term growth, and makes your content easier to crawl and rank.

In this guide, we’ll cover the principles of SEO-friendly architecture—from navigation and internal linking to URL strategy and taxonomy—so you can establish a web structure that’s both user-friendly and search-ready.

What is site architecture?

Site architecture, also known as website structure, refers to how a website’s pages are organized and connected to one another.

It covers how navigation, URLs, and internal links connect content into a hierarchy that both users and search engines can follow. Well-designed web architecture follows these three principles:

Why your site structure matters for SEO, UX, and business performance

A strong site architecture makes it easy for both visitors to find what they need and search engines to crawl and understand your content.

When navigation is intuitive, users stay on the site longer, convert more often, and are less likely to bounce to a competitor. At the same time, clear pathways and logical hierarchies help crawlers identify topical relevance and prioritize your most important pages.

These two sides—UX and SEO—work hand in hand.

Good architecture provides support both by guiding people through their journey and signaling authority to search engines. And when it’s built to scale, your site structure can accommodate new products, services, or content without breaking.

The result is a site that performs better in metrics across the board: user engagement, organic visibility, and long-term business growth.

Why site architecture is foundational to SEO

Having great site architecture significantly impacts search engine optimization (SEO) as factors like bounce rate, engagement, and link equity can be boosted when it’s done correctly—or damaged when it’s done wrong.

Architecture affects crawl depth and crawl budget

Crawl depth refers to how many clicks need to be made from the website’s homepage in order to reach a particular page. Generally, the fewer clicks it takes to reach a page, the more important that page is perceived to be by both people and search engines.

Conversely, when pages are buried too deep (beyond four clicks), search engines perceive them as less important, as they are less prominent on the site and more difficult for users to navigate to. This can push the page down in the search results, which is the last thing you want.

Additionally, the greater the crawl depth, the more difficult it is for crawlbots to find all of your content, which negatively impacts SEO and the site’s organic performance.

It’s also important to keep in mind that Google has a limited crawl budget for every site it visits. Every time Googlebot is on your site, it’s only going to visit a certain number of web pages. If pages are difficult to find and navigate to, a site’s crawl budget can be wasted as the crawlers may never reach deep enough to discover all of your pages.

Sometimes referred to as “link juice,” link equity is the perceived value and topical authority one page can pass to another page through a hyperlink. This means that internal linking can be a particularly effective way to boost a page that doesn’t yet have a lot of visibility.

Link Equity

For example, an authoritative, high-ranking product or service page on your website could link to a topically related explainer or guide page that hasn’t yet started to rank.

Each of these pages will feature internal links connecting them together, and the product page will pass some of its link equity onto the guide page, giving it a boost.

Not only do these pages now have a better chance of getting discovered and indexed by search engines, but the links also inform the crawlers of the relevance, value, and relationship between pages.

Architecture impacts user engagement and conversion paths

In terms of user engagement, people are less likely to bounce when the site’s navigation makes it easy to find what they’re looking for. Clean, intuitive, and user-friendly navigation can actually increase a user’s time on site because they’re able to happily explore more elements rather than leaving in frustration.

A well-planned site architecture is also critical for conversion paths, as it should smoothly guide the user to the conversion opportunity—whether this is buying a product or supplying their email—by first walking them through the content that primes them to convert and then removing any roadblocks that prevent them from doing so.

When the site’s architecture sends users down poorly designed conversion paths or hinders engagement, people are likely to leave the website and find an alternative from a competitor. This outcome results in the customer developing a poor view of the brand due to the negative experience, as well as the loss of a sale.

Architecture impacts how search engines understand site hierarchy and topical relationships

Your site’s architecture is one of the clearest signals search engines use to determine importance and relationships between pages. A shallow, well-organized hierarchy shows:

When content is grouped into clusters under a hub or parent page, search engines can understand the topical depth available on the site. They can see that you don’t just have a single page on the subject—you’ve built an entire ecosystem of related resources.

Internal links and logical URL paths reinforce those connections. A hub page on “technical SEO,” for example, that links to detailed guides on crawl budgets, schema markup, and site speed makes it obvious that your site has authority on the subject.

As Impression Digital explains, clear parent-child URL hierarchies and consistent linking patterns give Google explicit cues about topical coverage.

That makes it easier for the algorithm to understand which pages deserve to rank for competitive head terms, while still surfacing supporting content for long-tail queries. The stronger your structural signals, the stronger your perceived authority across the topic.

Good site architecture = Greater ranking potential

Best practices in website structure—like topically relevant internal linking, clear navigation, and shallow hierarchy—make it easier for web crawlers and search engines to understand the website, what it’s about, and how its pages relate to one another.

Using website structure to clearly demonstrate the topical authority of your site—like building topic clusters around key concepts—can easily be the secret weapon in your SEO toolbox.

Good architecture also provides a better chance of getting the content crawled and indexed. This is crucial, as getting your pages indexed is step one in getting them ranked.

Common types of website structures and when to use them

There are four common models of website structure, each offering different use cases:

Let’s dig into what sets each apart and why you may choose one over the other.

Hierarchical site structure

Hierarchical is the structural model that fits most websites and is widely used by businesses and directories. It’s probably the structural model that is most intuitive and easiest to understand at a glance.

Hierarchical Site Structure

Layout: The hierarchical model spreads out like a tree, with the homepage as the root. From there, the categories branch out, with more pages and topics spreading into their own clusters and sub-clusters.

Advantages: A strong hierarchy makes for a very SEO-friendly site structure as it offers clear navigation and URL paths. It’s intuitive and supports content growth as more pages can always branch off from an appropriate point.

Disadvantages: While this model easily allows for content growth, this structure must be employed with care on especially large sites or the hierarchy and its crawl depth could become too deep, causing crawling and indexing issues.

Sequential site structure

Sequential is a website structural model primarily used when the website user must view each piece of content in a particular order. This works well for a checkout process or for online classes and tutorials that require a step-by-step approach.

Sequential Site Architecture

Layout: This site structure has a clear starting and ending point, with navigation guiding the user through each step in-between.

Advantages: As it’s a clear and well-defined path, the site is simple for users to navigate through, and no relevant steps are likely to be missed.

Disadvantages: Sequential sites have a very rigid structure, so users are unable to skip steps to get to what they’re looking for, which could result in higher bounce rates. They are also confusing if users enter in the middle.

Additionally, search engines might not be able to crawl this structure effectively, as the content is often dynamic or utilizes navigation not accessible to crawlers.

Matrix site structure

A matrix website structure is best suited for news sites, big ecommerce websites, or any site with a large and diverse amount of content.

Image 85

Layout: Like the name would suggest, a matrix website structure doesn’t follow a linear or data-driven layout. Instead, it’s multi-dimensional like a grid, with users able to access content from different entry points. Matrix sites often feature multiple paths to reach the same piece of content.

Advantages: Matrix websites are user-directed and support advanced filtering and search.

Disadvantages: Search engines might struggle with crawling and fully indexing a matrix site, as the relational and hierarchical signals between pages tend to be less focused. This model also encourages numerous navigational pathways that can be confusing from a user-navigation standpoint.

Database site structure

Finally, a database site structure is where the content is stored in structured tables and can be found based on user inputs or queries.

It’s perfect for sites that receive consistent updates or that have large inventories of information.

Ecommerce platforms like Amazon and eBay are strong examples of websites that use this style.

Image 83

Layout: A database site structure doesn’t follow a fixed layout. It’s instead built on a modular structure.

For example, if a customer is looking for a product page, then this will not be stored as one file but is instead built from separate pieces of information (price, stock, category info, reviews, etc.). All of this is pulled together when the user clicks on the page.

Advantages: Database sites excel at scalability.

Any changes in the database will be immediately reflected on the live site, with one change simultaneously updating a large number of pages. Plus, as content is often dynamically generated based on user selections, users can easily find exactly what they’re looking for.

Disadvantages: SEO needs careful consideration on database sites. Dynamically generated URLs can lead to many issues, including index bloat and duplicate content. Also, as database sites can be more technical, additional backend infrastructure might be needed.

Other ways of thinking about site architecture

Once you’ve decided which site architecture model to use, you can tailor your structure and enhance your user experience by considering some of the following concepts.

Flat vs. deep site architecture

When structuring a website, pages can be arranged in two ways: flat or deep.

Flat Deep Architecture

Each model affects how easily search engines crawl your content and how quickly users can reach what they need. Here’s how they differ.

Flat architecture: Shallow and crawl-friendly

With a flat site architecture, most pages are accessible within three clicks from the homepage.

This keeps crawl depth shallow, making it easier for search engines to discover and index all content. Smaller to medium-sized sites often benefit the most from this model, since users can reach high-value pages quickly without getting lost in layers of navigation.

Best use: Prioritize a flat structure for evergreen guides, key categories, and high-value landing pages where crawlability and visibility are critical.

Deep architecture: Layered and scalable

A deep architecture places pages four or more clicks away from the homepage. This can make them harder for crawlers to reach and for users to navigate. However, for very large sites—such as ecommerce catalogs or news archives—deep structures can be practical. They help prevent choice overload by breaking navigation into manageable chunks.

Examples: Amazon’s vast product catalog and media sites with decades of archived articles both rely on deeper structures to keep navigation usable.

When to flatten your site architecture

Even on large sites, flattening is worth the effort for pages that matter most: evergreen resources, high-value categories, and critical conversion paths. These should be kept close to the root to maximize both user engagement and search visibility.

Hub-and-spoke model

Also called a topic cluster, the hub-and-spoke model has a central page (the hub) surrounded by the subtopic pages (the spokes).

Typically, the pillar page will broadly cover a topic, then the spoke pages cover subtopics in greater detail and link back to the hub.

This model is best used when targeting an expansive topic (e.g., social media marketing).

The structure helps to establish topical authority for competitive keywords by comprehensively covering a topic and entities related to it. It’s not ideal for ecommerce sites that are based on product pages, but it does work well for sites with a lot of informational content.

Siloed website architecture

A silo is a way of grouping website sections into distinct categories or topics. Each silo acts like a bucket—housing related content that reinforces a specific theme (e.g., SEO, email marketing) or audience segment (e.g., SEO managers, talent managers).

Two ways to create silos

Why silos matter

Silos signal topical relationships to search engines, boosting authority and helping users discover more relevant content. They reinforce vertical relevance by showing how topics connect within a category.

Pitfalls of over-siloing

Tightly isolating silos can backfire. If related topics aren’t linked across categories, users miss out on helpful content, and search engines may struggle to index orphaned pages.

If you choose this approach, you’ll need to balance silos with cross-links to maintain discoverability.

Faceted navigation

Also known as “faceted search,” faceted navigation is a type of user interface that allows users to filter search results by specific categories like size, color, brand, and so on.

Image 80

Faceted navigation is commonly used on ecommerce sites (or for job boards, directories, or booking systems) and allows potential customers to toggle results according to their preferences and see specifically what they’re looking for in an easy-to-navigate way.

While this makes the user experience highly personalized, it can cause SEO-related challenges with your site structure, requiring careful noindexing, canonicalization, and dynamic URL handling:

Noindexing

Apply noindex tags to low-value pages that don’t serve a purpose for organic traffic. This reduces index bloat and keeps search engines focused on the pages that matter.

Canonicalization

Use canonical tags to show search engines which version of a page should be prioritized. For example, /sweater?color=blue and /sweater?size=medium may display the same products. Without canonicals, each variation could be indexed separately and dilute ranking signals.

Dynamic URL handling

Dynamic URLs from filters, searches, or sort functions can create endless duplicates. Wherever possible, rely on clean, hierarchical URLs and set controls to prevent unnecessary parameter-based pages from bloating the index.

Best practices for SEO-friendly site architecture

Creating an SEO-friendly site structure is all about proactive planning and consistency in execution.

Seo Friendly Architecture

Use these four steps as a blueprint. Each one helps ensure your site is easy for both people and search engines to understand, while leaving room to grow as your content expands.

1. Build a shallow (flat) structure with clear hierarchy

Keep your most valuable and evergreen content close to the surface.

Why it works: A shallow structure makes it easier for crawlers to index your site, users to navigate quickly, and new content to find its natural place.

2. Outline a logical URL structure

Your URLs should mirror your content organization and site structure, not fight against it. Each URL should accurately reflect the page’s location, include relevant keywords, and be easy to understand and navigate for both users and search engine bots.

Why it works: Clear, consistent URLs reinforce topical relevance in search results and give users confidence they’re in the right place.

3. Develop intentional internal linking

Don’t just link randomly—link with purpose.

Why it works: Internal linking strengthens topical clusters, passes authority across pages, and guides users through a logical content journey.

4. Plan for scalable navigation and taxonomy

Think beyond today and design for when your content will need to scale at any point in the future. Before launching or restructuring, map your architecture visually (site maps, flow diagrams, or wireframes).

Seeing the hierarchy in diagram form makes it easier to spot gaps, dead ends, and overly complex paths.

Why it works: Scalable navigation ensures your structure stays intact as your site expands, making it easier for search engines to crawl and for users to find what they want.

URL architecture: Best practices

Think of your URLs as the blueprint for your site.

Best Practises

A strong URL structure makes your hierarchy clear, keeps crawlability simple, and makes content easier to share.

The good news? You don’t need to reinvent the wheel every time you create a new page. Just run through this checklist each time you create, adjust, or plan a new page.

Anatomy of a clean URL

A good URL acts like a signpost. It’s easy to read, mirrors your content hierarchy, and doesn’t add noise.

https://www.example.com/category/subcategory/page

Each part of that path tells both users and crawlers what the page is about and how it connects to your site.

Random IDs, strings, or meaningless parameters (like /page.php?id=123) add length and seeming gibberish rather than clarity. The clearer the signal, the more likely your page is to be clicked, crawled, and understood.

Keep URLs short and descriptive

Long URLs packed with filler words, dates, or tracking parameters dilute clarity. A short, descriptive path like /seo-audit instantly communicates value and is easier to share or remember:

Stop words in URLs

Words like and, the, or of help natural language flow in copy, but they serve no purpose in URLs.

They add bulk without improving clarity.

For both users and search engines, as long as the key terms are present, the meaning is clear. In fact, most stop words are removed during text processing in natural language algorithms—another reason they’re unnecessary in URLs.

How long is too long?

There’s no exact cutoff, but longer URLs create a worse experience.

They may get truncated in search results, are harder to read at a glance, and discourage sharing.

As a rule of thumb, keep URLs under 75 characters to make sure they’re easy to parse and display cleanly across screens.

Need another reason to keep your URL short? Shorter URLs are also less prone to breaking in copy-paste situations and look more trustworthy in search results.

Mirror your content hierarchy in the path

Your URLs should reflect how your content is organized. This does more than just keep your infrastructure clean; it also makes it easier for users and bots to find the location of each page.

For example:

/guides/website-structure/best-practices

This path shows the page belongs to a “website structure” guide.

It gives crawlers topical context and makes browsing easier for humans.

For larger sites, hierarchical URLs also reinforce hub-and-spoke models. For example, /blog/seo/technical/ signals technical SEO is a subset of SEO content, which itself resides on the site’s blog.

Keep critical pages close to the root

The further a page is from your homepage, the less likely search engines are to prioritize it. Shallow URL paths make important content more discoverable and distribute link equity more efficiently.

In general, a shallow URL structure supports crawl efficiency, while deep nesting can bury valuable pages.

To be clear, this doesn’t mean every page should be listed directly under the homepage. You still want a well-organized hierarchy in place. But for the pages you determine to be most valuable, the shallower the URL path, the easier it will be to find.

Use hyphens, not underscores

Google treats hyphens (-) as word separators. Underscores (_) can blur terms together for search engines.

/seo-audit is correctly read as “SEO audit.”

/seo_audit, on the other hand, may not be interpreted correctly.

In other words, hyphens provide clarity while underscores can lead to confusion for search engines.

Stick to lowercase

Everything after your domain can be case-sensitive.

That means /Widgets and /widgets could be read as two different URLs.

Using lowercase site-wide avoids accidental duplicates and broken links.

Avoid unnecessary parameters and session IDs

Dynamic parameters like ?session=123 or ?color=blue&size=large can create dozens of near-duplicate versions of the same page.

Google’s own guidance from over a decade ago calls out URL parameters as the primary cause of duplicate content.

Why is this a problem?

Duplicate content associated with multiple links can quickly burn through your crawl budget and muddy ranking signals by diluting the original source. Best practice is to:

Include keywords naturally

Keywords in a URL reinforce relevance, but only when used sparingly.

/seo-site-architecture is clear.

/seo-seo-site-architecture-optimization-seo looks manipulative. It also confuses both users and search engines. And it makes the URL incredibly long, increasing the likelihood of misattribution or cut-off links.

So, yes, insert relevant keywords into your URLs for clarity and context. Just don’t stuff them in, hoping it will benefit visibility (because it won’t).

Keep URLs stable

Constantly changing URLs for cosmetic reasons breaks links, creates redirect chains, wastes crawl budget, and erodes equity. Choose the best version up front and stick with it.

If changes are unavoidable:

Minimize “junk” in the path

Strip out what doesn’t add meaning: file extensions (.php, .html), version numbers, or filler words. example.com/about is cleaner and easier to maintain than example.com/aboutus-page-v2.html.

Less clutter = stronger signals.

Pro tip: Before publishing, sanity-check the URL. If you can’t tell what the page is about from the path alone, neither can your users (or Googlebot).

How site architecture affects crawling and indexing

Successful crawling and indexing are much more likely to happen when a site is properly organized and pages aren’t deeply buried.

Google, for example, has a variable crawl budget for each site, and the deeper the pages are, the more likely they are to go un-crawled and un-indexed.

When the site’s navigation and internal links are done well, bots are purposefully directed to important pages and new content, making discovery much more likely to occur before the crawl budget is exhausted.

XML sitemap = Safety net

As a crawl backup plan, it’s important to have an XML sitemap on your site and submitted to Google Search Console. The XML sitemap can be used by search engines to find URLs that aren’t easy to discover through crawling navigation and other internal links.

Whether pages are isolated or newer, an XML sitemap is functionally a second chance for the crawlers to find them.

But remember: XML sitemaps should act as a safety net and not a replacement for proper site architecture. XML sitemaps do not pass on topically relevant link equity or the topical authority that proper contextual pathways would.

Splitting large amounts of content into many smaller pages through pagination must be done correctly, or it can cause issues with duplicate content and greatly increase the site’s overall crawl depth, resulting in crawling and indexing problems.

To avoid pagination negatively affecting crawlability and indexing, follow these best practices:

Orphan pages can impact crawl and indexing performance

Orphan pages don’t have internal links pointing to them, depriving them of crawl paths, internal link equity, and topical relevance signals.

Orphan pages are also something to watch for, as they can be difficult to rank for keywords or to even get indexed or crawled in the first place.

Use a tool like Semrush’s Site Audit to discover orphan pages. You can then add a relevant link to the orphan page from another page on the website. This link shouldn’t, however, come from another orphan page.

Image 79

A noindex tag can also be added if the page was intentionally excluded from the website’s structure, or the orphan page can simply be deleted (with a proper redirect) if it serves no purpose.

How to use the Site Audit tool to identify orphan pages

Once logged in to Semrush:

1. Find the left sidebar and go to “SEO” > “On Page & Tech SEO” > “Site Audit.”

2. Set up a project for your website if you don’t already have one.

3. Click on “+ Create project” and follow the prompts; otherwise, click on your website in the project list.

Image 78

4. Click on the “Issues” tab.

From there, a number of identified errors and warnings will appear.

Image 81

To find your site’s orphan pages:

Type “orphan” into the search bar to find any problems related to orphan pages, such as “X orphaned pages in Google Analytics” or “X orphaned pages in sitemaps.”

Clicking on one of these results will provide you with a list of orphaned URLs that you can then analyze and resolve.

Using internal linking to support indexation

Internal links are an important pathway that crawlers use to discover, crawl, and index pages on a website.

Crawlers do this by following navigation and internal links to discover new content. When a page has more links pointed at it, search engines view the page as more valuable and authoritative.

To utilize internal linking to support indexation, follow these guidelines:

Topical authority comes from structure as much as content.

When related pages are grouped into clusters and supported by hub pages, you create a framework that highlights expertise, improves crawlability, and positions your site to rank for broader and more competitive terms.

How Google infers expertise from structure

Search engines look for patterns in how content is organized. A clear hierarchy and consistent signals show that your site covers a subject in depth, making it easier for people, algorithms, and LLMs to interpret topical expertise.

Group content into clusters

Organize related pages into clusters rather than scattering them across your site.

Each cluster should include a hub page that introduces the topic broadly, with supporting pages that explore subtopics in more depth.

Together, they demonstrate comprehensive coverage that a single page can’t (and often shouldn’t) achieve.

Interlinking reinforces context

Link hub pages to their spokes with descriptive anchor text, and make sure supporting content links back to the hub. This creates a strong web of relevance, ensures link equity flows throughout the cluster, and guides users through connected content paths.

Hub pages act as semantic anchors

Hub pages serve as the anchor of each cluster—the resource most likely to rank for competitive queries. Supporting content strengthens the hub’s relevance while also capturing long-tail searches. In competitive SERPs, clusters anchored by strong hub pages are often what separates sites that rank from those that don’t.

AI and site architecture: What advanced SEOs need to know

It’s easy to assume that optimizing for AI-driven search requires a completely different approach from SEO.

Different Approach

AI tools like Google Gemini, ChatGPT, and Perplexity don’t crawl and index in the same way as traditional search engines. They lean heavily on semantics, hierarchies, and relationships between entities rather than just crawl depth or raw link equity.

The reality is that most of the best practices already covered in this guide—clear hierarchies, descriptive URLs, strong internal linking, and schema—are the same principles that improve how LLMs interpret and cite your content.

The difference lies in emphasis.

Where classic search engine crawlers primarily needed pages to be accessible, AI models need them to be understandable at the chunk and cluster level.

That means advanced SEOs don’t need a brand-new playbook. You just need to evolve your approach: Prioritize semantic clarity alongside crawlability, and think about how your architecture helps AI models piece together topical authority.

How site structure impacts LLM crawlability and interpretation

Search engines crawl linearly, from link to link and page to page.

LLMs do more. They break sites down into entities, topics, and sections that can be independently retrieved.

A clear hierarchy, breadcrumb trails, and descriptive navigation signal to AI models how your content fits together, while inconsistent linking or deep nesting creates ambiguity.

A clean site structure improves chances of LLM citation and attribution

LLMs thrive on clarity.

The easier it is for AI systems to parse and interpret your site, the more likely your content will be considered trustworthy enough to reference.

In practice, that means the same elements that improve user experience and understanding—logical clusters, clear links, and consistent signals—are the very things that improve your odds of showing up in generative results.

Topical authority through clusters

Grouping related content around a hub page builds clear topical clusters. When subpages consistently point back to a central resource, it shows depth of coverage, which LLMs use to judge authority across a subject area.

Internal linking clarifies relationships

Links provide contextual signals.

When you connect related pieces of content with descriptive anchor text, you help AI models interpret how one page supports another.

This interconnectedness strengthens your site’s knowledge graph and increases the likelihood of surfacing in generative AI summaries.

Chunk-level retrieval makes content extractable

Generative systems don’t always pull an entire page. Instead, they often extract a single section via a process known as chunking.

Chunk-level retrieval is the process of breaking a page into semantically coherent pieces (like a subheading and the content that follows) and retrieving them independently.

Formatting content into clean, labeled sections with a clear scope makes it easier for models to lift and reuse those passages.

These same rules also apply to your site structure. When a logical, clear, and descriptive hierarchy is used, it can help LLMs ingest and chunk information before even reaching a page.

Schema reinforces hierarchy and markup signals

Schema markup turns implied relationships into explicit ones. By tagging elements like breadcrumbs, FAQs, and articles, you’re spelling out page purpose and context in a machine-readable way.

Why does this matter?

Large language models and search engines don’t just look at your copy—they analyze how different parts of your site connect. Schema gives them a structured roadmap.

Here are a few examples:

The net effect? Schema reduces guesswork.

While there’s no definitive proof that schema usage provides additional weight in LLMs’ consideration of a resource, when done consistently, it gives AI a clearer context to follow.

When AI systems can clearly map what your page covers and how it connects to related topics, they’re more likely to surface it as a trusted source in AI-powered summaries, and doing so can increase the odds of being cited correctly.

Flat architecture reduces friction

Critical content buried several levels deep is less likely to be surfaced. Keeping key pages closer to the root makes them more prominent to both crawlers and AI systems.

Tips to make your site structure more attractive to LLMs

There’s no silver bullet for getting your content picked up by LLMs. If there was, we’d all be doing it already.

However, by focusing on the following five tips (which you should be doing to create clear and understandable site architecture anyway), you will increase your chances.

Cluster by theme

Build hub-and-spoke models around your core topics. Pillar pages should act as anchors, with supporting content pointing both out and back in.

Clustering allows AI systems to easily understand your depth of coverage and creates semantic clarity that can be interpreted into topical authority.

Use descriptive URLs and clear headings

Keep URL slugs human-readable and semantically meaningful. Combine that with heading structures that reflect the hierarchy of your site so AI models can follow how sections and pages connect to one another.

Standardize schema markup

Apply structured data consistently across pages. Breadcrumb, FAQ, and Article schema help make relationships explicit, giving AI a clearer roadmap of your site architecture.

Audit and connect orphan pages

Crawl your site to identify content with few or no internal links. Reinforce those pages with connections to relevant hubs or category pages so nothing sits outside your topical graph.

Keep important content shallow

Place your most critical pages within one or two clicks of the homepage. Shallow structures reduce friction and signal priority. This improves visibility for both traditional crawlers and AI-driven retrieval.

Site architecture cannot be an afterthought

Even with great content or products, a poor structure will hold your site back. Architecture shapes how easily pages are crawled, indexed, and ranked—and how smoothly users move through your funnel.

Whether you’re making incremental improvements or planning a full rebuild, focus on three fundamentals: Choose the right structural model, keep navigation intuitive, and build an internal linking system that reinforces your authority.
