A URL slug is a crucial element of your website’s structure, impacting both user experience and search engine rankings. It is the final segment of a web address that uniquely identifies a specific page. While it may seem like a minor detail, a well-crafted URL slug can contribute to the overall effectiveness of your SEO strategy and help users easily understand what the page is about.
Imagine visiting a site and seeing two URLs: one like https://website.com/blog/ followed by https://website.com/blog/82354. The first clearly indicates the content focus, while the second offers no insight whatsoever. This simplicity and clarity in URL structure not only improve readability but also increase the likelihood of clicks, especially when the URL accurately reflects the page content.
In this guide, we’ll explore what URL slugs are, why they matter for SEO, best practices for creating effective slugs, and how to manage them within platforms like WordPress. Whether you’re building a new website or optimizing an existing one, understanding URL slugs can help you enhance both your site’s usability and its search engine visibility.
What Is a URL Slug?
A URL slug is the last part of a webpage’s URL that identifies the specific page. It usually appears after the domain name and any folder paths, serving as a concise descriptor of the page content. For example, in the URL https://semrush.com/blog/what-is-a-url-slug/, the segment what-is-a-url-slug is the slug.
This part of the URL acts as a virtual signpost, guiding users and search engines alike. Effective slugs are typically short, descriptive, and easy to read, providing immediate context about the page’s subject matter. They can include relevant keywords, but overstuffing keywords in the slug should be avoided, as it can harm user experience and SEO.
A well-structured URL, including a clear slug, enhances navigation and can even influence how your pages appear in search results. For example, a URL like https://website.com/seo-tips instantly signals the content focus, making users more inclined to click.
Why Is a URL Slug Important for SEO?
Although the influence of URL slugs on SEO is considered lightweight, it remains a factor worth paying attention to. Google’s John Mueller has confirmed that words in a URL can contribute to ranking signals. However, he emphasizes that their impact is minimal compared to other SEO elements, such as high-quality content and backlinks.
The primary benefit of a well-optimized slug is improving user experience. When users see a URL that clearly indicates the page’s content, they are more likely to trust and click on the link. This is especially true in search engine results pages (SERPs), where short, relevant URLs stand out more effectively.
For example, consider these two URLs:
https://website.com/blog/rock-climbinghttps://website.com/blog/82354
The first URL provides meaningful information about the content, increasing the chances of engagement. In contrast, the second offers no clues, which could discourage clicks despite similar content quality.
Additionally, including target keywords naturally within your URL slugs can help search engines understand the relevance of your pages to specific queries, improving your chances of ranking higher. However, overdoing it can backfire, so focus on creating user-friendly URLs that align with SEO best practices.
URL Slug Best Practices
To maximize the benefits of URL slugs, follow these best practices:
Be Descriptive
Your slug should accurately describe the page’s content, making URLs more user-friendly. Use keywords thoughtfully, ensuring they fit naturally within the slug. For example, /best-air-purifiers is more informative than /2575, which offers no context.
Make It Concise and Readable
Keep your URL slugs short—ideally fewer than five words—to enhance readability and prevent truncation in search results. Long URLs can be cumbersome and less attractive to users. For instance, /abs-exercises is preferable over /the-best-abs-exercises-for-all-levels-of-gym-goer.
Include Your Target Keyword
Incorporating keywords in your slug helps search engines understand your page’s relevance. For example, a page targeting “keyword research” should have a slug like /keyword-research. Avoid keyword stuffing, but ensure the URL remains natural and descriptive.
Separate Words Clearly
Use hyphens to separate words in your URL slugs. Hyphens improve readability and are favored by search engines over underscores or other separators. For instance, /good-old-fashioned-pancakes is better than /good_old_fashioned_pancakes.
Use Lowercase Characters
Always stick to lowercase in URLs to avoid issues with case sensitivity and typos. Consistent lowercase URLs are easier to type and less prone to errors, such as /new-york instead of /New-York.
Avoid Special Characters and Emojis
Stick to ASCII characters and avoid special symbols or emojis in URLs. Search engines may have difficulty interpreting these, and they can appear unprofessional. For example, /emoji-meanings is preferable over /😊🚀.
Make It Future-Proof
Avoid including dates, numbers, or other elements that might change over time. Use timeless language to ensure your URL remains relevant and accurate long-term. For example, /how-to-write-url-slugs instead of /10-tips-to-write-url-slugs-in-2022.
URL Slugs in WordPress
Managing URL slugs in WordPress is straightforward. First, ensure your permalink structure is set to a user-friendly format, such as “Post name.” You can do this by navigating to “Settings” > “Permalinks” in your WordPress dashboard.
When editing a post or page, you can modify the slug directly in the editor. Click on the “Link” section or the permalink below the title to customize it. If using the Yoast SEO plugin, you can also edit the slug in the SEO panel at the bottom of the post editor.
Always remember to set up a 301 redirect if you change an existing URL slug. This preserves your SEO efforts and prevents visitors from landing on a 404 error page. Proper redirects ensure your link equity and traffic are maintained over time.
Check Your Website for URL Issues
Regularly auditing your website for URL-related problems is vital. Use tools like Semrush’s Site Audit to identify issues such as:
- URLs with special characters or spaces
- Excessively long URLs
- URLs with unnecessary parameters
Addressing these issues can improve crawlability and user experience. For example, URLs with too many parameters might lead to duplicate content issues, which can be mitigated by proper canonicalization.
Optimize Your URL Slugs
Effective URL slugs contribute to your overall SEO strategy. Keep them descriptive, concise, and keyword-rich where appropriate. Use tools like Semrush’s Site Audit to identify and fix URL issues, ensuring your URLs remain optimized for both users and search engines.
