Have you ever clicked on a link and instantly understood what the page was about? That’s the power of a well-optimized URL slug. It not only enhances user experience but also plays a crucial role in SEO (Search Engine Optimization).

A clear, concise URL slug helps search engines and users quickly grasp the content of a webpage.

A typical search result must include:

• Title (Meta Title)
• Description (Meta Description)
• URL

In this guide, we’ll cover everything you need to know about URL slugs, including best practices, SEO benefits, and how to optimize them effectively in 2025.

What is URL & Slug?

A URL (Uniform Resource Locator) is a web address that helps you find a website or page online. It includes the protocol (like https), the website name (like example.com), and the page path (like /blog).

A URL slug is the part of a webpage’s URL that comes after the domain name and helps identify the page. That means it’s the last part of the webpage’s URL.

For example, Consider the following URL:

Full URL:

https://example.com/small-business-seo

The Slug is: 

small-business-seo

A well-optimized URL slug is short, descriptive, and includes relevant keywords for better understanding and search rankings.

The URL gets bigger when the slug gets bigger.

Why is a URL Slug Important?

A properly optimized URL slug provides several advantages, including:

• SEO Benefits – Search engines analyze URL slugs to understand a page’s topic.
• Higher Click-Through Rate (CTR) – A clear, well-structured URL slug encourages more clicks from search results.
• Improved Site Structure – Well-organized URLs help users and search engines understand website hierarchy.
• Better Sharing: Short, readable URL slug examples are easier to share and remember.
• User-Friendly Navigation: A clear slug for home page or any other page helps visitors understand what to expect. It improves navigation and user trust.

Does URL slug affect SEO? Yes, a well-optimized URL slug helps search engines understand page content, improving rankings. A concise, keyword-rich slug can improve search rankings.

John Mueller from Google (Search) has talked about how keywords in URLs affect search rankings many times. I’m sharing here are some update key points he has made:

In 2021, SEO Office Hours:

“We use the words in a URL as a very, very lightweight factor. And from what I recall, this is primarily something that we would take into account when we haven’t had access to the content yet… But as soon as we’ve crawled and indexed the content there, then we have a lot more information.”

Best Practices of URL Slugs for Beginners (From Google Recommendation)

To ensure your URL slugs are optimized, follow these best practices:

1. Keep It Simple and Descriptive

Generally, Google prefers shorter URLs.  

A concise slug improves readability and SEO. Avoid unnecessary words and focus on the core topic. If the slug is large, the URL will usually be large.

A slug should be 2-6 words long and clearly describe the page content.

🔹Good: best-seo-practices 

🔹Bad: a-complete-guide-to-seo-best-practices-in-2025

Shorter URLs are easier for users to read, type, and share. Google also prefers shorter URLs because they focus on the main topic without extra clutter.

Problem with Long URLs:

• Hard to remember
• May get cut off in search results
• Makes users less likely to click

2. Use Hyphens (-), Not Underscores (_)

Search engines recognize hyphens (-) as word separators, while **underscores (_) **are not recommended.

Google recommends that you use hyphens (-) instead of underscores (_) in your URLs.

Source: Google Search Central

Google treats hyphens as word separators, but underscores do not separate words.

Problem with Underscores:

• example.com/seo_url_optimization → Google reads this as “seourloptimization”
• Makes URLs harder to read

3. Include Target Keywords

Using primary keywords in your slug enhances search visibility, but avoid keyword stuffing.

🔹Good: how-to-optimize-url-slug 

🔹Bad: seo-url-slug-best-guide-seo

Keywords in URLs help search engines understand the page content and improve ranking for those keywords.

Problem with Too Many Keywords:

• Google may see it as spam
• Can look untrustworthy to users
• Harder to read and understand

4. Avoid Special Characters and Stop Words

Skip symbols (&, %, $, @) and common words like “and,” “the,” “of,” etc., to keep slugs clean.

🔹Good: seo-strategies

🔹Bad: seo-and-the-best-strategies

Special characters can break URLs or make them hard to share.

Problem with Special Characters:

• Some browsers don’t support certain symbols
• URLs with symbols might not copy correctly

5. Make It Readable and Meaningful

A good slug should be easy to read and understand.

🔹Good: wordpress-url-slug-guide 

🔹Bad: wp-urlsg-2025

6. Keep It Lowercase

Some servers are case-sensitive, so always use lowercase letters.

🔹Good: seo-best-practices 

🔹Bad: SEO-Best-Practices

Some servers treat uppercase and lowercase letters as different URLs, which can lead to duplicate content issues.

Problem with Uppercase Letters:

• example.com/SEO-Best-Practices and example.com/ seo-best-practices may be seen as two different pages
• Confusing for users and search engines

7. Avoid using dates for Future-Proof

Avoid including years or dates unless necessary. If your content is evergreen, using “2025” in the slug may make it outdated next year. Example:

🔹Good: www.example.com/url-slug-tips

🔹Bad: www.example.com/url-slug-tips-2025

Google also recommends Using words in your audience’s language in the URL. For example, if your audience is searching in German, use German words in the URL. 

How to Optimize URL Slugs in WordPress

If you’re using WordPress, follow these steps to optimize your slugs:

1. Change the Permalink Structure

By default, WordPress URLs may not be SEO-friendly. To change this:

• Go to Settings > Permalinks in your WordPress dashboard.

• Select Post Name (example.com/sample-post/) or a custom structure for better readability.

2. Edit the URL Slug in Post/Page Editor: 

• Open the Post or Page editor.
• Locate the Link section.
• Edit the Slug field with a concise, keyword-rich phrase.

• Click Update to save changes.

You can also easily edit or write the slug in the slug section.

How to Change an Existing URL Slug in WordPress

Changing an existing URL slug in WordPress is simple. But requires careful handling to avoid SEO issues. Follow these steps:

1. Edit the URL Slug in the WordPress Editor

From WordPress Dashboard,

• Go to Posts > All Posts (or Pages > All Pages).

• Click Edit on the post/page you want to update.

• In the Yoast SEO meta box (below the post editor), locate the Slug field.

Then,

• Edit the slug to make it short, keyword-rich, and readable.
• Click Update to save changes.

2. Set Up a 301 Redirect (Prevent Broken Links & SEO Issues)

Since the old URL may already be indexed, setting up a 301 redirect is essential.

Method 1: Using a Plugin (Recommended)

• Install and activate the Redirection plugin.

• Go to Tools > Redirection and follow the setup process.
• Click Add New Redirect:
  • Source URL: Enter the old slug (e.g., /old-url-slug/).
  • Target URL: Enter the new slug (e.g., /new-url-slug/).

• Click Start Setup and Add Redirect.

Method 2: Using Yoast Premium (Easy)

If you have Yoast SEO Premium, it automatically suggests creating a redirect:

• After updating the slug, Yoast will prompt:
  “You’ve changed the URL. Do you want to redirect the old URL to the new one?”
• Click Yes to create the 301 redirect.

Method 3: Using .htaccess (Advanced Users)

If you prefer manual redirection, add this line to your .htaccess file:

{Copy code}

Redirect 301 /old-url-slug/ https://yourwebsite.com/new-url-slug/

Be cautious when editing .htaccess, as incorrect changes can break your site.

3. Update Internal Links

After changing the slug:

• Update internal links in your content to use the new URL.
• If you have a menu with the old URL, update it via Appearance > Menus.

4. Inform Google About the Change (Optional but Recommended)

To help Google recognize the updated URL faster:

• Go to Google Search Console.

• Use URL Inspection to request indexing for the new URL.

5. Test the Changes

• Visit the old URL to ensure it redirects properly.
• Check the new URL for correct formatting and functionality.

⚠️ WARNING:

Changing your permalinks settings can seriously impact your search engine visibility. It should almost never be done on a live website.

FAQs

What is the difference Between URL and Slug?

It’s common to confuse a URL with a slug, but they serve different purposes:

• URL: The full web address or the full path of the website. It contains the protocol, domain name, and slug respectively. (https://example.com/blog/url-slug-best-practices).
• Slug: The specific part after the domain (url-slug-best-practices).

A URL slug is just one part of the full URL that should be optimized for clarity and SEO benefits.

Should You Use a Slug for Your Home Page?

No, you generally should not use a slug for your home page. In WordPress and most websites, the home page URL should remain clean and simple, like:

✅ example.com/ (No slug needed)

Why Avoid a Slug for the Home Page?

• Better User Experience – A short and clean URL is easier to remember and share.
• SEO Best Practices – Search engines prioritize home pages without unnecessary slugs.
• Default WordPress Behavior – WordPress automatically sets the home page URL as the root domain (/).

When Might You Use a Slug?

If your home page is a landing page within a larger website, you might use a slug:
example.com/home/ (Only if necessary for site structure)

For most cases, avoid adding a slug to your home page and keep it simple with just your domain name!
