A WordPress permalink is a URL intended to keep pointing to a post or page. Choose a structure before launching a new site. For an established site, first decide whether a change is necessary: a cosmetic preference alone may not justify migrating many URLs. This guide separates initial setup from a planned URL change.
Permalinks, URL Paths and Slugs Explained
Calling every part of a URL a permalink makes a change request ambiguous. Following the WordPress permalink explanation, break an example into its components.
Term | Example | Meaning |
|---|---|---|
Complete URL | scheme + :// + hostname + path | The page’s permalink |
Scheme | https | The connection scheme |
Host | example.com | The destination host |
Path | /blog/permalink-guide/ | The location within the host |
Post slug | permalink-guide | The identifying text for this example post |
A common structure and an individual post slug are also different settings. Either may affect a published address, so record the existing URL before editing.
Choose a URL Structure for a New Site
For a new site, consider both readability and what future edits could change the URL. A structure less dependent on categories or dates may simplify maintenance where those values change frequently. Do not automatically apply a new-site preference to an existing site.
Structure | Reason to choose it | Change dependency | Existing-site decision |
|---|---|---|---|
Post name /sample-post/ | A readable content identifier | Changing the slug changes the URL | Keep a working structure if migration is unnecessary |
ID ?p=123 or /archives/123 | Stable identification by ID | The subject is less obvious from the address | The format alone does not prevent search inclusion |
Date /2026/10/11/sample-post/ | Publication date forms part of the organization | Check effects of date edits | Weigh a real need against migration work |
Category /topic/sample-post/ | Classification appears in the path | Category edits may affect the URL | Identify affected addresses before reorganizing |
Google’s URL structure guidance supports readable words and the audience’s language. Non-ASCII text is not inherently an SEO failure. Select a naming policy around the audience, sharing behaviour, and maintainability instead of automatically replacing existing Japanese or other localized URLs.
Set the Structure and Post Slug in WordPress
With appropriate permissions, WordPress exposes common structures under Settings and Permalinks. Select the structure and save it. Exact labels and behaviour can vary with the version, permissions, and hosting environment; refer to the official settings documentation.
- Establish whether this is a new or existing site and record current settings.
- Choose a candidate structure and inspect an actual resulting URL.
- Review the individual slug in the post editor.
- Test page links, listing links, and output before launch.
- If saving reports a server-side requirement, consult the implementation owner.
A new slug should summarize the content and follow a consistent team policy. Hyphens can separate words. This is not an instruction to rewrite every published localized or ID-based address.
Decide Whether Existing URLs Need to Change
Existing URLs may appear in external references, bookmarks, email campaigns, and internal navigation. Identify the reason and impact before changing a common setting.
Situation | Starting decision | Next step |
|---|---|---|
A cosmetic preference | Consider keeping existing URLs | Check whether copy or title improvements are enough |
Necessary restructuring or business migration | Define the affected scope | Build a URL map and migration plan |
Redirects cannot be implemented or tested | Reconsider timing | Secure an owner and test environment |
Only the article body needs updating | Keep that separate from migration | Do not treat a rewrite as a URL-change requirement |
Old links do not inevitably become 404s: inspect the actual responses and redirects. Equally, correct redirects do not promise that search visibility will remain unchanged throughout a migration.
Map Old URLs and Test Permanent Redirects
Map old URLs to relevant new destinations. The Google guide to URL-changing moves covers permanent server-side redirects and coordinated updates to links, canonicals, and sitemaps. Avoid sending unrelated old pages to the homepage.
Check | Fictional example or evidence |
|---|---|
Old to new | /old-guide/ → /blog/guide/ |
Old response | 301 or 308 directly to the intended destination |
Final destination | Intended content and a final 200 response |
Redirect steps | No unnecessary intermediate chain |
Canonical | Intended new reference and actual output |
Internal links | Update menus, listings, and related links |
Sitemap | Verify the current new URL is included |
Query parameters | Test retention of required UTM values separately |
Handover | Owner, date, results, important referral paths |
Google generally recommends retaining redirects for at least a year. A URL migration does not guarantee a fixed percentage of ranking retention or a recovery date. Also consider how long customers may continue to use old links.
Monitor Search and Analytics After a Change
After launch, separate technical success from search and analytics observations. A correct redirect does not mean that every report immediately moves to the new address.
- Test old URLs through to their intended final destinations.
- Check retrieval, indexing, and canonical information for new URLs.
- Track old and new search impressions and clicks under consistent conditions.
- In GA4, match host, language, period, and channel while retaining separate old/new path rows.
- Evaluate outcomes only with tested success and duplicate-counting definitions.
A path is useful for classifying content, but it does not identify the visitor’s channel. A /blog/ page can receive advertising visits, and a /campaign/ page can receive organic visits. Keep URL organization separate from source analysis and causal claims about marketing performance.
