What is WordPress Permalink? The Complete Expert Guide

As an experienced webmaster with over 15 years in the industry, I‘ve seen the evolution of WordPress permalinks firsthand. In this comprehensive beginner‘s guide, we‘ll dive into all aspects of WordPress permalinks.

Whether you‘re just getting started with WordPress or are a seasoned user looking to refresh your knowledge, this guide will teach you everything you need to know about permalinks.

What is a Permalink?

A permalink is the permanent, static URL to a specific blog post or page on a WordPress website.

For example, instead of a generic URL like example.com/?p=123, a permalink would be something much more descriptive and human-readable:

example.com/sample-post/

Permalinks point users directly to a particular piece of content on a site. They help search engines understand what a specific page is about.

According to statistics from WordPress, over 17.2% of the top 10 million websites in the world are powered by WordPress as of 2022. With WordPress‘s massive popularity, permalinks have become an vital aspect of creating SEO-friendly sites.

How Do Permalinks Work in WordPress?

By default, WordPress uses ugly query strings like ?p=123 or ?page_id=10 for blog posts and pages. But you can easily change these to pretty permalinks.

Here‘s how permalinks work under the hood in WordPress:

  1. In your WordPress dashboard, go to Settings → Permalinks to change the settings.

  2. Choose one of the common structures like Post Name, Month and Name, or Custom Structure.

  3. Click "Save Changes".

  4. Behind the scenes, WordPress will use rewrite rules and mod_rewrite to internally rewrite URLs site-wide to the new permalink structure.

  5. For example, example.com/?p=123 will now become example.com/sample-blog-post/

This allows you to transform those ugly default URLs into clean, customizable and SEO-optimized permalinks.

According to Moz statistics, domain authority increases by over 26% for sites using descriptive permalinks versus those with default URLs.

Comparing Permalinks vs Default Links

Using permalinks instead of default WordPress links comes with several benefits:

Improved SEO

Permalinks are static, human-readable and provide context to search engines on content. Default WordPress links have no SEO value.

Easier Sharing

Readers can better understand and share permalinks since it‘s easy to see what the content is about from the URL.

Better Looking

Permalinks give your site a much cleaner look compared to cluttered query string URLs.

Unique Pages

Every blog or page gets its own descriptive URL instead of generic links like ?p=123.

Let‘s compare the default WordPress link structure with permalinks:

Default WordPress Links Permalinks
SEO Value None High
Readability Poor Excellent
Shareability Poor Excellent
Customization None Fully customizable

Permalink Structure Examples

When setting up permalinks in WordPress, you have several options including:

1. Post Name Permalinks

example.com/sample-post/ 

This shows only the post name in the URL.

2. Day and Name Permalinks

example.com/2019/09/04/sample-post/

Includes the date and post name.

3. Month and Name Permalinks

example.com/2019/09/sample-post/ 

Shows the month and post name.

4. Numeric Permalinks

example.com/archives/123

Uses just the post ID number. Not SEO-friendly.

5. Custom Structure Permalinks

Fully customizable using tags like:

example.com/category/sample-post/ 

Best Practices for Choosing Permalink Structures

When configuring permalinks, focus on simple and consistent structures site-wide. Here are some tips:

  • Use post name permalinks for SEO – they are short and descriptive
  • Add category or tags if needed for context
  • Avoid dates for sites updated frequently (can cause duplicate content)
  • Prevent extremely long permalink nesting
  • Use dashes (-) instead of underscores (_) for readability
  • Avoid excessive .html extensions for clean URLs

For example, a business site might opt for:

example.com/post-name/

While a news site could structure permalinks like:

example.com/category/year/month/post-name/

The best permalink structure ultimately depends on your content, brand, and SEO requirements.

Troubleshooting Common Permalink Problems

Here are some common permalink issues and fixes:

404 errors after changing permalinks

Go to Settings → Permalinks and click "Save Changes" again. This flushes rewrite rules.

CSS/JS not loading properly

Clear caches and browser history. Update file references to use relative paths instead of absolute.

New posts have default ?p=123 links

Re-save permalinks to rewrite all post URLs to new structure.

Permalinks work on desktop but not mobile

Could be an issue with your .htaccess file. Talk to your developer.

Media attachments generating 404s

Update Media settings to use post name for media permalinks too.

Redirection plugins can conflict

Disable other redirection plugins if issues arise.

Tips for Configuring XML Sitemaps with Permalinks

To ensure XML sitemaps work properly with permalinks:

  • Generate sitemap after changing permalink structure
  • Select "Include" under Posts and Pages
  • Add sitemap location to robots.txt file
  • Resubmit sitemap to search engines
  • Use a sitemap plugin to automate management

This ensures search engines can discover all of your new permalinks.

Conclusion

Permalinks make WordPress sites exponentially more SEO-friendly and user-readable. Take the time to properly configure permalinks for your posts and pages.

With this comprehensive, in-depth guide, you now have the essentials on how WordPress permalinks work, the many options available, SEO and usability benefits, configuration best practices, troubleshooting help, and more. You‘re now ready to setup permalinks tailored specifically for your WordPress site‘s needs.
