URL Structure
URL structure is the architecture of your web addresses — the path that tells Google and users what a page is about before they visit it. Clean, keyword-inclusive URLs are a small but real ranking signal and a major usability and trust factor.

Google reads URLs as a relevance signal — the slug (the part after the domain) is one of the first things Googlebot processes when evaluating a page. A URL like /on-page-seo/title-tags immediately communicates topic and hierarchy. A URL like /page?id=47 communicates nothing. The difference isn't dramatic in isolation, but across an entire site it contributes to how well Google understands your content architecture.
URL structure also reflects and reinforces your internal linking and site hierarchy. In a topic cluster architecture, the path directly mirrors the silo — the T2 sub-pillar is the parent path, and T3 cluster pages sit beneath it. This makes the topical relationship between pages explicit to Google before it reads a single word of content.
One critical rule: once a URL is live and indexed, don't change it without a 301 redirect. Changing a URL without redirecting destroys any ranking authority the old URL had accumulated. This is one of the most common and most damaging mistakes made during site redesigns. Plan your on-page SEO URL strategy before you build, not after.
URL Structure Checklist
- All pages served over HTTPS
- Hyphens used between words (not underscores)
- Lowercase letters only
- Primary keyword in the slug
- No unnecessary parameters or dynamic strings
- URL depth matches content hierarchy
- Short and human-readable
- No dates in URLs (creates staleness)
- 301 redirects set for any changed URLs
Anatomy of a URL — Every Component Explained
Every URL has up to six distinct components. Here's what each one does and its SEO implications.
| Component | Example | What It Does | SEO Note |
|---|---|---|---|
| Protocol | https:// | Indicates the communication standard. Always HTTPS — HTTP is a ranking penalty and trust signal failure. | Required. Non-HTTPS sites are flagged as insecure in Chrome. |
| Domain | griffinmottconsulting.com | Your root domain. Shorter, brandable domains are preferred. Avoid hyphens in the domain itself. | Domain authority builds over time. Don't change it without a full redirect strategy. |
| Subdomain | blog.example.com | A prefix before the root domain. Google typically treats subdomains as separate sites from the root. | Avoid subdomains for SEO content — use subfolders (/blog/) to keep authority on the root domain. |
| Path / Slug | /on-page-seo/url-structure | The page-specific portion of the URL. Reflects site hierarchy and communicates the page topic. | Include the primary keyword. Use hyphens. Keep it short. Match your content architecture. |
| Query String | ?ref=homepage | Dynamic parameters appended after a ?. Used by CMS platforms, tracking systems, and filters. | Avoid indexable URLs with query strings — use canonical tags or robots.txt to handle duplicates. |
| Fragment | #faq-section | Links to a specific section within a page. Not sent to the server — only used by the browser. | No direct ranking impact, but useful for user experience and jump links in long-form content. |

Frequently Asked Questions
What are the different types of URL structures?
The main URL structure types are: flat structures (example.com/page-name) where all pages sit at the root level, hierarchical structures (example.com/category/page-name) that reflect topic relationships, and silo structures (example.com/seo/keyword-research) that group topically related content under a parent path. For SEO, hierarchical and silo structures perform better because they signal content relationships to Google and pass authority more efficiently.
How do I create a URL structure?
Start with your site architecture — map out your main topics and subtopics before creating URLs. Use hyphens to separate words, keep URLs as short as possible while remaining descriptive, include the primary keyword for that page, and match the URL to the content hierarchy. For a service page: griffinmottconsulting.com/seo-services-kansas-city. For a sub-page: griffinmottconsulting.com/on-page-seo/title-tags.
What is the purpose of a URL structure?
URL structure serves three purposes: it tells Google what a page is about (the slug contains keyword signals), it communicates page hierarchy and topic relationships (parent/child paths reflect content architecture), and it helps users understand where they are on a site before they click. A well-structured URL also earns better natural link text when other sites link to it.
What are the components of a URL structure?
A URL has five components: the protocol (https://), the domain (griffinmottconsulting.com), the path or slug (/on-page-seo/url-structure), the query string (?parameter=value), and the fragment (#section-id). For SEO, the protocol, domain, and path are most important. The path should be clean, keyword-inclusive, and human-readable.
What are best practices for URL structure?
URL best practices: use HTTPS, use hyphens not underscores between words, keep URLs short and descriptive, include the primary keyword in the slug, avoid unnecessary parameters or dynamic strings, use lowercase letters only, reflect your site hierarchy in the path, and never change a URL without setting up a 301 redirect from the old URL to the new one.
