Why URL Structure Matters for WordPress SEO
URL structure is a fundamental aspect of SEO. In WordPress, poorly structured URLs can negatively impact your site’s visibility, while well-optimized permalinks enhance crawlability, clarity, and click-through rates.
Key Characteristics of an SEO-Friendly URL
- Readable: Easy for humans to understand
- Keyword-Rich: Contains relevant keywords naturally
- Short and Concise: Avoids unnecessary words or parameters
- Static: Doesn't change over time or rely on dynamic strings
- Consistent: Follows a uniform format across the entire website
Choosing the Best Permalink Structure in WordPress
Default vs Custom Permalinks
WordPress offers multiple permalink settings. The default plain URL (?p=123
) is not SEO-friendly and should be avoided. Instead, choose or create a structure that includes the post name and optionally a category or date if relevant.
Recommended SEO-Friendly Permalink Structures
/%postname%/
– Clean and simple, great for evergreen content/%category%/%postname%/
– Adds topic context, good for niche content
How to Change Your Permalink Structure
Go to Settings > Permalinks in your WordPress dashboard and select your preferred structure. If your site is already live, be careful—changing permalinks without proper redirection can break links and harm SEO.
Best Practices for Optimizing WordPress URLs
1. Include Target Keywords
Each URL should reflect the content topic and include primary keywords without stuffing or duplication.
2. Avoid Stop Words and Unnecessary Terms
Remove filler words like "the", "and", "of", "to", unless essential for meaning. Keep URLs as short as possible.
3. Use Hyphens to Separate Words
Google recommends using hyphens (-
) instead of underscores to improve readability and parsing.
4. Make URLs Case-Insensitive
Use lowercase letters consistently to avoid duplicate content issues and confusion with file paths on some servers.
5. Avoid Using Dates in URLs (for Most Blogs)
Dates can make content look outdated even if it’s evergreen. Exceptions include news websites or time-sensitive portals.
6. Use Canonical Tags When Needed
For pages with similar or duplicate content, use canonical URLs to point search engines to the preferred version.
Implementing Redirection After URL Changes
If you change existing URLs, implement 301 redirects to preserve SEO equity. Use plugins like Redirection or manage it via your .htaccess file if you're comfortable editing server configurations.
Examples of Good vs Bad URLs

Using Categories and Tags in URLs
Should You Include Categories?
Including categories can improve topical relevance and clarity, but can also lead to longer URLs. Use only when your category structure is stable and well-planned.
Avoid Using Tags in Permalinks
Tags are more useful for internal taxonomy and not recommended as part of the URL structure.
Technical SEO Considerations
1. Avoid Duplicate URLs
Don’t let multiple URLs lead to the same content. Use canonicalization, remove trailing slashes consistently, and monitor duplicate content issues with SEO tools.
2. Internal Linking with Clean URLs
Always use the shortest version of a URL in your internal links. Keep them consistent in structure across your site.
3. Robots.txt and URL Accessibility
Ensure important URLs are not being accidentally blocked via robots.txt or noindex tags.
