How to Create SEO-Friendly URLs: 15 Best Practices

1. Add Clear Keywords to URLs

Adding relevant keywords to your URLs can make a big difference for both search engines and users. In fact, a 2023 Backlinko study showed this approach can lead to better click-through rates.

The key is to strike a balance between being descriptive and keeping it short. Here’s how you can do it:

Use Focused Keywords Wisely

Pick 1-2 specific keywords that accurately describe your content. Place the main keyword at the start of the URL for better visibility. For instance, instead of using something like:

/blog/how-to-make-the-best-chocolate-chip-cookies-recipe-easy-quick

Go for:

/recipes/chocolate-chip-cookies

Avoid Overloading with Keywords

Resist the urge to cram too many keywords into your URL. Overstuffed URLs can feel unnatural and hurt readability.

Align URLs with Content

Make sure the keywords in your URL match the content on the page. This builds trust and ensures relevance.

"URLs with words that are relevant to your site’s content and structure are friendlier for visitors navigating your site." – Google

Tools to Find the Right Keywords

If you’re not sure where to start, keyword research tools can help. Here are some options:

"URLs are a stable foundation. Once set, changing them can cause more harm than good, leading to broken links and lost SEO juice – unless properly managed with redirects".

Lastly, keep your URLs concise while ensuring they’re still clear and descriptive.

2. Make URLs Brief

Short URLs aren’t just about looking good – they’re about improving user experience and boosting SEO. Research shows that concise URLs perform better for social sharing and are easier for users to engage with. Combine brevity with smart keyword use, and you’ll see better results in both trust and search rankings.

Why Short URLs Are Important

Short URLs come with several benefits:

• Easier to remember and type
• Cleaner appearance in search results
• More shareable on social media
• Less prone to typos when entered manually

Google’s John Mueller explains: "The direct answer is no. The URL length doesn’t matter. We use URLs as identifiers, it doesn’t matter how long they are. Personally, I try to keep them shorter than 1,000 characters, but that’s just to make monitoring easier".

Tips for Shortening URLs

Here’s how to make your URLs shorter while keeping them effective:

Managing URL Parameters

To keep URLs clean without losing functionality, follow these steps:

• Combine duplicate parameters
• Remove empty values
• Keep parameter order consistent

For example, instead of:

https://example.com/page?filter=red&filter=red

Use:

https://example.com/page?filter=red

A study by Brafton revealed that shorter URLs receive more social shares. When trimming URLs, focus on clarity and remove anything that doesn’t add value or context to the page.

Next, learn why clear URL paths are essential for better navigation.

3. Use Hyphens Between Words

How you separate words in URLs affects both SEO and user experience. Google specifically advises using hyphens (-) instead of underscores (_) or spaces.

Why Hyphens Work Best

Google’s algorithms see hyphens as word separators, making it easier to understand the content of a URL. On the other hand, underscores are treated as word joiners.

"Consider using hyphens to separate words in your URLs, as it helps users and search engines identify concepts in the URL more easily. We recommend that you use hyphens (-) instead of underscores (_) in your URLs." – Google

How Word Separators Influence URL Interpretation

Here’s a quick comparison of different word separators:

"There’s a difference and that’s in our segmenter. Basically we use some parts of the URL for understanding what the page is about…we can’t easily segment at underscore and that’s why we are recommending dashes."

Why Hyphens Matter

Using hyphens in URLs offers several clear advantages:

• Better Search Engine Understanding: Hyphens help search engines accurately interpret and index your content.
• Improved Accessibility: Screen readers and voice assistants process hyphenated URLs more effectively.
• Cleaner User Experience: Hyphenated URLs are easier to read and share, especially on social media.
• Higher Click-Through Rates: Clear, readable URLs are more likely to attract clicks.

Consistency is key – stick to hyphens in all your URLs for a polished look and stronger SEO performance. When updating or creating new URLs, always choose hyphens to separate words. It’s a small change that can make a big difference.

4. Create Clear URL Paths

A well-structured URL path helps both users and search engines understand your site’s layout, improving navigation and indexing. Start by organizing your hierarchy to reflect your website’s structure.

Organizing URL Hierarchy

The best URL structures follow a logical order, moving from broad categories to specific content. This setup should align with your website’s natural architecture while allowing room for future updates. Once your hierarchy is planned, stick to these basic principles to keep it clear.

Best Practices for URL Organization

Follow these guidelines to ensure your URL structure is easy to understand and navigate:

• Keep the hierarchy simple: Stick to three levels or fewer for better clarity.
• Enable directory access: Make sure users can move backward through the hierarchy without issues.
• Group similar content: Use subfolders to logically organize related content. For example, blog posts might go under /blog/, while products stay under /products/.

Avoiding Common Pitfalls

Be consistent when assigning URLs to content that fits into multiple categories. For example, instead of creating duplicate paths, choose one clear route, like www.example.com/products/cool-product/.

Impact on Search Performance

Research on over one million Google search results shows that clear, keyword-rich URLs often rank higher. Google itself advises using "simple URL structures" and "descriptive words" in your URLs.

Take some time to refine your URLs by removing unnecessary elements and keeping them straightforward.

5. Skip Special Characters

Special characters can cause issues with links, parsing, and sharing, making URLs harder to manage.

Common Problematic Characters

Why Encoding Special Characters Is an Issue

When special characters are included in URLs, they need to be percent-encoded, which can make them harder to read and prone to errors. For example, a product URL like "1/2 ct Diamond Earrings" should be formatted like this:

• Correct: example.com/jewelry/1-2-ct-diamond-earrings
• Incorrect: example.com/jewelry/1%2F2-ct-diamond-earrings

Using clear, simple URLs helps avoid these complications.

Tips for Cleaner URLs

To keep URLs functional and easy to use, follow these tips:

• Stick to alphanumeric characters (a–z and 0–9).
• Replace spaces with hyphens instead of encoding them.
• Avoid special characters whenever possible.
• Simplify fractions (e.g., write "1/2" as "1-2" or "half").

Handling URLs in Content Management Systems

When setting up URLs, ensure your CMS handles them properly. As John Mueller from Google advises:

"I generally recommend avoiding special characters like commas, semicolons, colons, spaces, quotes etc. in URLs, to help keep things simple." – John Mueller, Google

For developers, encoding functions can help manage URLs. For instance:

let documentName = "financial report Q1/Q2.pdf";  
let encodedDocumentName = encodeURIComponent(documentName);  
// Result: financial%20report%20Q1%2FQ2.pdf

SEO and Crawling Implications

Overly complex URLs can hurt SEO by making crawling and indexing more difficult. Google adheres to URL standards outlined in RFC 3986, so simpler URLs are generally better for search performance. If you must use special characters, consider setting up 301 redirects from encoded URLs to cleaner versions to maintain SEO value.

6. Stick to Lowercase Letters

Using inconsistent capitalization in URLs can hurt your SEO and lead to broken links. While domain names aren’t case-sensitive, everything after the domain often is – especially on Unix-based servers.

Why Lowercase URLs Are Important

Mixed-case URLs can cause a range of problems, including:

Best Practices for Using Lowercase URLs

1. Adjust Your Server Settings
   Configure your server to automatically enforce lowercase URLs. For Apache servers, you can use this rule in your .htaccess file:

   RewriteEngine On
   RewriteMap lc int:tolower
   RewriteCond %{REQUEST_URI} [A-Z]
   RewriteRule (.*) ${lc:$1} [R=301,L]
   

2. Set Up Your CMS
   Ensure your CMS automatically converts URLs to lowercase and redirects older uppercase URLs to their lowercase versions.

Avoid Common Errors

"Maintaining uniformity in URL capitalization ensures that search engines accurately index and understand the structure of a website." – SEOptimer

Instead of relying on uppercase letters for readability, use hyphens to separate words. Here’s an example:

• Wrong: example.com/Flights/GermanyToUK
• Right: example.com/flights/germany-to-uk

How to Fix Mixed-Case URLs

If your site already has mixed-case URLs, follow these steps to clean things up:

1. Set up 301 redirects from uppercase to lowercase URLs.
2. Update all internal links to use lowercase versions.
3. Add canonical tags pointing to the lowercase URLs.
4. Check server logs to identify uppercase URL requests.
5. Update external and internal links to ensure consistency.

Now that you’ve got lowercase URLs sorted, let’s move on to updating legacy URLs without disrupting your SEO.

7. Put Keywords First

Using keywords at the beginning of your URLs can improve SEO and make navigation easier for users. Search engines prioritize words that appear early in URLs when assessing page relevance.

Impact on Search Rankings

Placing keywords at the front of URLs helps search engines quickly grasp the content’s focus, making it more relevant for specific queries.

Effective Keyword Placement

Start your URL with the primary keyword to clearly reflect the page’s topic.

"URLs with words that are relevant to your site’s content and structure are friendlier for visitors navigating your site." – Google

Best Practices for Keyword Positioning

• Match the Content’s Focus: Place the main keyword at the beginning while keeping the URL natural and logical.
• Keep It Readable: Ensure the structure is easy for users to understand.

"It strikes the perfect balance, offering categorization without overwhelming users." – Jacob Kettner, CEO of First Rank

• Avoid Overloading Keywords: Stick to 1-2 main keywords to avoid over-optimization.

Practical Implementation

Compare these two examples:

• Not optimized: example.com/blog/2025/03/05/comprehensive-guide-to-search-engine-optimization
• Optimized: example.com/seo-guide

The improved version leads with "seo", maintaining clarity and purpose. This approach helps both search engines and users quickly identify the page’s content, potentially boosting its relevance for specific searches.

Next, we’ll explore how to further refine your URLs by removing unnecessary words.

8. Delete Unnecessary Words

Trimming extra words from URLs not only improves readability but also makes them more effective for both users and search engines. Just like hyphens help separate words for better understanding, cutting out filler words keeps URLs focused and clear.

Stop Words to Remove

Common words to cut include:

• Articles: a, an, the
• Conjunctions: and, or
• Prepositions: of, to, for, etc.

Impact on URL Structure

Why It Matters

Simplifying URLs offers several advantages:

• Easier to read and type: Short URLs reduce the risk of typing errors.
• Improved SEO: Every remaining word adds more value for search engines.
• Better user experience: Clearer links make it easier for users to understand the content at a glance.

"URLs don’t require stop words, such as the, and, or, of, a, an, to, for, etc., to convey meaning. They are perfectly fine without them." – stanventures.com

How to Optimize

Follow these tips to clean up your URLs:

• Focus on essential keywords.
• Remove articles, prepositions, and other filler words.
• Avoid including dates unless they add necessary context.
• Use numbers only when they’re relevant to the content.

The end goal? URLs that are simple, clear, and meaningful – making them easy for both search engines and users to understand without any unnecessary clutter.

Next, we’ll explore how to ensure URL stability to maintain SEO effectiveness.

9. Keep URLs Permanent

Keeping URLs consistent is key to maintaining your website’s SEO strength over time. When other websites link to your content, they pass on SEO value, known as link equity. This value grows stronger when your URLs remain unchanged.

Why Consistent URLs Matter

Stable URLs offer long-term benefits, including:

• Backlink consistency: Other websites linking to your content won’t need updates.
• Stable search rankings: Search engines reward unchanging URLs with better rankings.
• Improved trust and click-through rates: Users are more likely to trust clean, permanent URLs.
• Fewer broken links: Reduces the risk of visitors landing on error pages.

Best Practices for Permanent URLs

Tips for Creating Permanent URLs

When designing URLs, follow these guidelines:

• Plan ahead: Decide on a durable URL structure early in your website’s development to avoid frequent changes.
• Stick to static URLs: Static formats are easier for users and search engines to handle.
• Avoid time-sensitive elements: Remove dates or other temporal details unless absolutely necessary.

"Use a recurring URL, not a new URL for each occurrence of the event. Give the landing page of recurring events a meaningful URL that reflects the event that is used each year (for example: use /sale/black-friday, not /sale/2020/black-friday)." – Google

What to Do If URLs Must Change

Sometimes, URL updates are unavoidable. Here’s how to handle it:

• Set up 301 redirects: Redirect the old URL to the new one to preserve link equity.
• Update internal links: Ensure all links within your website point to the new URL.
• Monitor traffic: Keep an eye on site performance after the change.
• Document changes: Maintain a record of all URL updates for future reference.

"URLs are the building blocks of your website and when optimized, can help increase your website traffic. Clean URLs perform better in search, appear more trustworthy, and make it easier to share." – Emily White, Graphic and Website Designer, Design Powers

10. Set Up URL Redirects

Redirects are essential when URLs need to change. They help maintain your site’s SEO value and ensure a smooth user experience.

Types of Redirects for Different Scenarios

Best Practices for Redirects

• Avoid redirect chains: Always link directly to the final URL to prevent unnecessary hops.
• Match content closely: Ensure the new URL aligns with the original content to avoid soft 404 errors.
• Keep redirects active: Maintain them for at least a year so search engines can fully register the changes.

"Knowing which URL redirect to implement on your site will prevent future obstacles that can negatively impact your site’s performance" – Kalpesh Guard, CFO seoClarity

"When a URL changes, our systems need to see the change in the form of a redirect for at least a few times in order to record that change" – John Mueller

Technical Implementation Tips

To set up redirects effectively, use server-side methods such as:

• Apache: Modify the .htaccess file to create 301 or 302 redirects.
• PHP: Use the header() function for dynamic redirects.
• Other platforms: Adjust configurations based on your hosting environment.

Redirect all relevant content types, including web pages, images, PDFs, and other downloadable files, to ensure comprehensive coverage.

Monitoring and Maintenance

Once your redirects are live, regular monitoring is key to ensuring they work properly. Here’s how:

• Check server logs: Look for redirect chains or errors.
• Use Search Console: Identify crawl errors and fix them promptly.
• Update internal links: Point them directly to the final URLs to avoid unnecessary redirects.

Conclusion

Optimized URLs play an important role in improving search rankings and building user trust. Here’s a quick look at the main benefits they bring:

"Keeping URLs as simple, relevant, compelling, and accurate as possible is key to getting both your users and search engines to understand them (a prerequisite to ranking well)".

When done right, URL optimization supports rankings, link sharing, and technical SEO. Here’s how:
