In website operations, URL structure is often overlooked, yet it becomes one of the most costly aspects during a redesign. Many corporate websites, after running for a while, face issues such as broken old links, lost authority, and the need for time-consuming 301 redirects when adjusting sections or migrating pages. So, how can you design URL structures for section pages to minimize future modification costs? This article provides concrete insights from design principles, common issues, and operational recommendations.
Impact of URL Structure on Future Redesigns
URLs are the unique addresses of web pages. Search engines use them to identify content, and users rely on them to understand page hierarchy. Poorly designed URL structures can lead to the following problems during a redesign:
- Broken old links: After page migration, old URLs become inaccessible, causing user bookmarks and external links to fail.
- Scattered authority: Using different URLs for the same content disperses search authority, leading to unstable rankings.
- Complex redirects: A large number of 301 redirects are required, increasing maintenance workload, and misconfigured redirects can result in 404 errors.
- Higher operational costs: Each redesign requires re-planning URLs, updating sitemaps, and adjusting internal links, consuming both time and manpower.
Therefore, planning URL structures early in the operational phase can significantly reduce future redesign costs.

Basic Principles of URL Structure Design
A well-designed URL structure should have the following characteristics:
- Readability: URLs should reflect content topics, making them easy for both users and search engines to understand.
- Clear hierarchy: URLs should reflect the site's section levels but not be too deep—generally no more than three levels.
- Stability: Once published, URLs should remain unchanged whenever possible, even if sections are adjusted.
- Simplicity: Avoid long, meaningless parameters, and use hyphens to separate words.
- Use pinyin or English: For Chinese websites, use pinyin or English words, but maintain a consistent strategy.
Example
// Recommended
/chanpin/fuwu/
/news/gongsidongtai/
// Not recommended
/index.php?id=123&cat=45
/admin/news_list.php?page=2
Key to Reducing Redesign Costs: The Principle of URL Stability
The core of minimizing future modification costs is keeping URLs stable throughout the website's lifecycle. Specific measures include:
- Plan sections in advance: During the initial website build, reserve enough room for section expansion based on business development and content planning, avoiding frequent changes to section names.
- Avoid dates or version numbers: Do not include easily changeable information like years, months, or version numbers in URLs (e.g., /news/2023/xxx), as they require updates annually.
- Use IDs or aliases: For content detail pages, use fixed IDs or aliases so that even if sections change, the detail page URLs remain unchanged.
- Maintain directory structure stability: If section adjustments are necessary, prioritize changing in-page navigation rather than modifying URLs.

URL Migration Strategy for Section Page Adjustments
If section page URLs must be changed, consider the following strategies to minimize impact:
- Inventory old URLs: List all pages that need migration, recording the mapping between old and new URLs.
- Set up 301 redirects: Permanently redirect old URLs to new ones to ensure users and search engines reach the correct pages.
- Update internal links: Modify all internal links pointing to old URLs across the site to avoid long redirect chains.
- Update the sitemap: Regenerate a sitemap containing new URLs and submit it to search engines.
- Monitor 404 errors: Regularly check access logs or use tools to identify and handle 404 pages promptly.
Note: 301 redirects are the standard way for search engines to migrate pages, but configuration must be careful to avoid loops or redirects to irrelevant pages. For large-scale changes, process in batches and monitor indexing and traffic changes.
Operational Planning of URLs to Reduce Maintenance Costs
From an operational perspective, you can take the following steps:

- Develop URL guidelines: During the website build phase, create a URL usage guideline document for developers and editors to follow.
- Use pseudo-static URLs: Convert dynamic URLs to static-looking ones to improve user understanding and search engine crawling.
- Avoid parameter proliferation: Tracking parameters (e.g., utm_source) should not affect the main URL, or use canonical tags to specify the authoritative URL.
- Audit URLs regularly: Check URL health quarterly or semi-annually, addressing any broken or non-compliant URLs promptly.
Common Questions and Misconceptions
Question 1: Is it okay to include Chinese characters in URLs?
Chinese characters in URLs are automatically encoded by browsers and recognized by search engines, but they are not user-friendly for copying and sharing. It is recommended to use pinyin or English.
Question 2: Can I simply delete old pages during a redesign?
It is not advisable to delete pages directly. Instead, use 301 redirects to the corresponding new pages; otherwise, old links become 404s, losing traffic and authority.
Question 3: If a section name changes, must the URL change too?
Not necessarily. The directory name in the URL is just an identifier; it can remain stable while only the navigation label changes. This minimizes SEO impact.
Conclusion
URL structure is the foundation of website architecture. Operations teams should prioritize stability during initial planning and subsequent adjustments. By following URL design principles, establishing guidelines, and using 301 redirects appropriately, you can effectively reduce redesign costs and make website operations more efficient. It is recommended to plan URLs before the site goes live and evaluate the impact on existing links with every adjustment, avoiding long-term issues caused by short-term actions.
