What is a URL Slug and Why Is It Important for SEO?
A URL slug is the part of a web address that comes after the domain name and identifies a specific page. For example, in the URL blog.siwtech.com/url-slug-generator/, the slug is url-slug-generator. It is the human-readable identifier that tells both users and search engines what the page is about.
URL slugs are a confirmed Google ranking factor. According to Google’s official URL structure guidelines, words in a URL carry weight in search rankings — particularly when they match the user’s search query. Furthermore, a clean, keyword-rich SEO-friendly URL improves click-through rates from search results because users can immediately understand what the page is about before clicking.
Beyond rankings, URL slugs also matter for social sharing, backlink anchor text, and user experience. A page with the slug wordpress-seo-guide gets significantly more clicks than one with a slug like post-12345 or page-id-6789. You can verify this impact yourself by checking your click-through rates in Google Search Console.
What Are Stop Words and Should You Remove Them from URLs?
Stop words are common words like “a”, “an”, “the”, “and”, “or”, “but”, “in”, “on”, “at”, “to”, “for”, “of”, “with” — words that appear frequently in written text but carry very little SEO value in a URL. In the context of URL slug optimization, removing stop words creates shorter, cleaner, more keyword-focused URLs.
For instance, the title “How to Build a WordPress Website for Small Business” would generate the slug how-to-build-a-wordpress-website-for-small-business without stop word removal — that is 9 unnecessary words in the URL. With stop word removal enabled, our tool generates build-wordpress-website-small-business — shorter, cleaner, and more keyword-dense.
However, there are cases where keeping certain words improves readability. Our tool lets you toggle stop word removal on or off depending on your needs — giving you full control over your SEO URL structure. As Yoast SEO recommends, the best slug is one that is short, descriptive, and contains your focus keyword.
Hyphen vs Underscore in URL Slugs — What Does Google Prefer?
This is one of the most common questions about URL slug best practices — and the answer is clear. Google strongly prefers hyphens (-) over underscores (_) as word separators in URL slugs. According to Google’s own URL structure documentation, Google treats hyphens as word separators — meaning “url-slug-generator” is read as three separate words. Underscores, on the other hand, are treated as connectors — “url_slug_generator” is read as one single word.
In practice, this means a URL with hyphens ranks for individual keyword searches, while a URL with underscores may only rank for the exact underscore-connected string. Therefore, always use hyphens in your SEO-friendly URL slugs — our tool defaults to hyphen separator for this exact reason.
When to Use Underscores
Underscores are acceptable in file names and database identifiers — but not in page URLs meant for SEO. If you are building a custom web application or naming image files, underscores are fine. For any public-facing URL slug that you want to rank in Google, always use hyphens.
URL Slug Best Practices for WordPress in 2025
Following these URL slug best practices will significantly improve your WordPress SEO performance. Additionally, consistently applying these rules across all your posts creates a clean URL structure that Google rewards:
- Keep it short — ideal URL slug length is under 50 characters. Shorter slugs are easier to read, share, and remember. Google shows full URLs in search results — shorter ones get cut off less.
- Include your focus keyword — your main keyword should appear in the slug. For a post about “WordPress SEO tips”, the slug should be wordpress-seo-tips — not post-1234.
- Use lowercase only — URLs are case-sensitive on most servers. YourSite.com/Post-Title and yoursite.com/post-title can be treated as two different pages — causing duplicate content issues. Always use lowercase.
- Remove stop words — articles, prepositions, and conjunctions add length without adding SEO value. Our URL slug generator removes them automatically.
- Avoid special characters — characters like &, %, #, @, and spaces create URL encoding issues (%20, %26 etc.) that look messy and confuse crawlers.
- Never change slugs after ranking — once a page starts ranking, changing its URL slug breaks existing backlinks and loses accumulated link equity. If you must change a slug, always set up a 301 redirect.
- Avoid dates in slugs — including the year in your slug (/2025/wordpress-seo-guide) makes content appear outdated quickly. Timeless slugs like /wordpress-seo-guide rank better long-term.
After creating optimized slugs with our tool and publishing your content, always verify your new URLs are being properly indexed by submitting them in Google Search Console using the URL Inspection tool. Then track organic traffic improvements in Google Analytics over the following weeks.
How to Change a URL Slug in WordPress
Changing a URL slug in WordPress is straightforward. However, there is an important SEO precaution to take before making any changes. Here is the complete process:
- Go to WordPress Admin → Posts (or Pages) and open the post you want to edit
- In the right sidebar, find the Permalink section — click on it to expand
- Edit the URL slug field and enter your new optimized slug from our generator
- If the post is already published and ranking, install the Redirection plugin and set up a 301 redirect from the old URL to the new one before saving
- Click Update to save the new slug
- Go to Google Search Console → URL Inspection → enter the new URL → Request Indexing
Furthermore, if you use Yoast SEO plugin, it will warn you when your focus keyword is not in the slug — making it easy to keep your slugs optimized consistently across all your WordPress posts.

A URL slug is the part of a web address that identifies a specific page — for example, in blog.siwtech.com/url-slug-generator/, the slug is url-slug-generator. A well-optimized slug is short, lowercase, uses hyphens as separators, contains the focus keyword, and has no special characters or stop words.
Yes, URL slugs are a confirmed Google ranking factor. According to Google’s URL structure guidelines, keywords in a URL carry weight in search rankings. A keyword-rich, clean slug also improves click-through rates from search results, which further boosts rankings.
Always use hyphens (-) in URL slugs. Google treats hyphens as word separators, so “url-slug-generator” is read as three separate words. Underscores (_) are treated as connectors — “url_slug_generator” is read as one word — which hurts your keyword rankings. Our tool defaults to hyphens for this reason.
Stop words are common words like “a”, “the”, “and”, “or”, “in”, “for” that carry little SEO value in a URL. Removing them creates shorter, cleaner, more keyword-focused slugs. For example, “how-to-build-a-wordpress-website-for-small-business” becomes “build-wordpress-website-small-business” — shorter and more keyword-dense. As Yoast recommends, keep slugs short and descriptive.
Yes, but with caution. If a page is already ranking, changing its URL slug breaks existing backlinks and loses link equity. Always set up a 301 redirect from the old URL to the new one using the WordPress Redirection plugin. Then submit the new URL in Google Search Console for re-indexing.
The ideal URL slug length is under 50 characters — shorter is better. Long slugs get truncated in search results and are harder to read and share. Our SEO quality checker flags slugs over 50 characters and recommends trimming them. Focus on including just the main keyword and 1-2 related terms.
