Site Architecture for SEO: Structure, Click Depth and Service Sites
Good structure helps people and Google find the pages that matter, quickly.
Google says it can use information such as the number of links it needs to follow to reach a page, and the number of links to a page, to infer that page’s relative importance. It also says it generally doesn’t use URL structure to work out site structure; links do that job.
So site architecture is mostly about menus, hubs and internal links.
Short answer: Good site architecture puts your most important pages within a few clicks of the home page, groups related pages under clear hubs (services, locations, categories, guides), links hubs to detailed pages and back, and avoids orphan pages. For a service business, a simple model is Home > Services hub > each service > supporting guides, with location pages only where you genuinely serve and can add local detail.
Key Takeaways
- Important pages should be few clicks from the home page.
- Links, not URLs, define structure for Google.
- Hubs group related pages and route users.
- Every page you care about needs internal links.
- Keep it simple; flat enough to navigate, structured enough to understand.
A model for service businesses
| Level | Pages | Links to |
|---|---|---|
| Home | Overview, main services, proof, contact | Services hub, key services, contact |
| Services hub | All services with short summaries | Each service page |
| Service pages | One per service | Related guides, relevant locations, contact |
| Location pages (if genuine) | Areas served with real local detail | Relevant services |
| Guides | Answers to customer questions | Relevant service, related guides |
Click depth
Aim to keep important pages within about three clicks of the home page. Shopify’s own guidance gives the same rule of thumb. Deep pages aren’t invisible, but fewer links and more steps can signal lower importance.
Stores
Home > categories > subcategories > products, with every product linked from a category. See e-commerce SEO checklist.
Checks
- Find orphan pages (orphan pages).
- Use descriptive menu and link text (internal linking).
- Breadcrumbs on deeper pages.
- Avoid thin location pages (doorway pages).
Frequently asked questions
Is a flat structure better for SEO?
Important pages should be easy to reach, but structure also needs to make sense to people. Balance both.
Do URL folders define my site structure for Google?
Google says it generally doesn’t use URL structure for that; internal links matter more.
Should every page be in the main menu?
No. Key pages in menus; others reachable from hubs and related links.
