The Best URL Structure: Thematic Grouping
URL structure quietly determines whether your entire website succeeds or fails.
Short, clean URL structures only matter because they influence crawl depth, internal linking, and how authority flows through your site.
Hub pages always outrank their child pages because hubs sit closer to the homepage, get crawled more often, and accumulate far more internal links and backlinks.
A page becomes a hub not because of its URL, but because the architecture, internal links, and backlinks all signal its importance.
Clusters, silos, hubs + spokes, and entity attribute pairs are all similar concepts: grouping related pages under a single authoritative topic hub.
Top-level hub pages must target broad, high-value keywords because every child page exists to reinforce the hub.
Child pages only rank well when they live inside a strong topical cluster built around a powerful hub page.
Top-level URLs rank better because they sit higher in the hierarchy and get discovered and recrawled more frequently.
Hub pages attract dramatically more internal links and backlinks than any individual child page, amplifying their ranking power.
Broad hub pages always rank for hundreds or thousands of keywords, while child pages can only rank for narrow intent queries.
You must build both a broad hub page and many attribute-level child pages to maximize keyword coverage and dominate a full topic.
Planning site architecture from the start guarantees the strongest results because you can build clean clusters without messy redirects.
Changing URL structures on existing sites requires 301s and updating internal links, which introduces risk but can dramatically improve rankings when executed correctly.
Structural URL layouts organize content by type, but they waste top-level pages that could be used for powerful ranking hubs.
Structural hubs like “/tools” or “/generators” cannot rank for broad queries because search intent favors thematic, comparison, or solution-focused pages.
If a top-level structural page cannot rank, every child page under it becomes weaker because the parent passes no authority downstream.
A thematic URL structure always outperforms a structural one because it groups pages around actual user intent and entity relationships.
Thematic hubs consistently outrank structural URLs because they align with search behavior and accumulate stronger authority
Top-level thematic hubs earn better rankings because they receive more internal links, stronger backlinks, and more frequent crawls.
Thematic hubs unlock dozens of subtopics, creating high-authority folder structures.
Housing related resource content inside the same thematic folder reduces cannibalization and reinforces topical relevance.
Placing blog posts under a separate structural folder like “/blog/…” increases the chance of cannibalizing your core pages because it creates a disconnected section of the site.
A unified thematic folder prevents cannibalization by keeping all contextually related pages under one clear, authoritative hub.
Thematic structure is not always possible depending on your CMS, but whenever it is, it produces higher rankings, more clicks, and more LLM visibility.
Navigational pages like Contact or Pricing should follow simple structural URLs because they are not traffic drivers.
Local SEO must prioritize location-first URL structures because locations outrank services in local search intent every time.
Location hubs like “/idaho/…” must house all service pages to make the location page dominant for every local query.
Reversing this structure (putting locations under services) cripples rankings because service hubs cannot compete with location hubs.
E-commerce sites must use thematic product category hubs like “/sneakers/” because they have far more ranking potential than “/mens-shoes/”.
URL structure influences internal linking, which influences crawl depth, which influences authority, which influences ranking. Everything works together.
Top-level pages qualify for exponentially more keywords, get more backlinks, and become the engines that power your entire cluster.
You must intentionally design a site architecture where every child page strengthens its hub and every hub strengthens the domain.
Competitor URL structures are useful reference points, but you should never assume they are correct. Many sites structure pages poorly.
A superior thematic URL structure makes it easier to outrank competitors even with similar content.
Planning site architecture can be done with a simple spreadsheet or a visual tool like GlooMaps. But clarity matters more than tooling, I just use sheets.
Find thematic URL opportunities before defaulting to structural folders because those choices determine your long-term rankings.
