No, slugs should only contain lowercase letters, numbers, and hyphens. This tool automatically removes invalid characters.
What Is a URL Slug?
A URL slug is the portion of a web address that appears after the domain name and identifies a specific page in a human-readable format. For example, in the URL example.com/best-seo-tools, the slug is best-seo-tools. Unlike query parameters or auto-generated IDs, slugs are designed to be clean, descriptive, and easy for both users and search engines to understand. A well-crafted slug tells visitors exactly what to expect on the page before they even click.
Why Slugs Matter for SEO
Search engines use URL slugs as one of many ranking signals. A descriptive slug that contains relevant keywords helps search engines understand the topic of your page, which can improve your position in search results. Google has confirmed that words in a URL provide a slight relevance signal. Beyond algorithms, readable slugs also improve click-through rates because users are more likely to click on a link that clearly describes the destination. Shared links on social media and in emails also look more trustworthy when they contain meaningful words rather than random numbers or codes.
Good Slugs
- /blog/improve-page-speed
- /products/wireless-headphones
- /guide/start-freelancing
Short, descriptive, keyword-rich
Bad Slugs
- /blog/post?id=48291
- /p/a7f3b2c1d9e5
- /page/How_To_Improve_Your_Page_Speed_In_2025
Random IDs, too long, underscores, uppercase
The SEO Impact of URL Structure
While the URL slug itself is a minor ranking signal, its indirect effects on SEO are significant. Here is how URL structure influences search performance:
- Click-Through Rate (CTR): Google displays the URL in search results. A clean, readable slug like
/guide/start-freelancingis far more inviting to click than/page?id=7823. Higher CTR sends positive signals to search engines. - Anchor Text from Links: When other websites link to your page using the URL itself as the anchor text, a keyword-rich slug acts as natural anchor text, reinforcing relevance.
- User Trust and Sharing: Clean URLs are shared more often on social media, messaging apps, and email. Each share is a potential backlink or traffic source.
- Crawl Efficiency: Search engine crawlers can more easily understand your site structure when URLs follow a consistent, hierarchical pattern. This helps with proper indexing.
- Keyword Relevance Signal: Google uses the words in the URL path as one of hundreds of ranking factors. While not as strong as page title or headings, it adds to the overall relevance score.
Slug Best Practices
Effective slugs follow a set of well-established guidelines. Keep them short, ideally between three and five words, so they remain readable and do not get truncated in search results. Use only lowercase letters, numbers, and hyphens as word separators. Avoid underscores, spaces, and special characters because they can cause encoding issues and look messy in the browser address bar. Remove stop words like "a," "the," "and," and "of" when they add no meaning. Focus on including your primary keyword naturally without stuffing. Once a page is live and indexed, avoid changing its slug unless absolutely necessary, and if you must change it, set up a 301 redirect from the old URL to prevent broken links and preserve link equity.
Slug Best Practices Checklist
| Rule | Bad Example | Good Example | Why |
|---|---|---|---|
| Use lowercase | /Blog/My-Post | /blog/my-post | Prevents duplicate URL issues on case-sensitive servers |
| Use hyphens, not underscores | /my_blog_post | /my-blog-post | Google treats hyphens as word separators; underscores join words |
| Remove stop words | /how-to-build-a-website | /build-website | Shorter URLs are easier to read and share |
| Include target keyword | /post-12345 | /react-hooks-guide | Keywords in URLs help with relevance signals |
| Keep it short (3-5 words) | /the-complete-beginners-guide-to-learning-react-hooks-in-2025 | /react-hooks-guide | Long URLs get truncated in search results and are hard to share |
| No special characters | /cafe%CC%81-guide | /cafe-guide | Encoded characters look messy and are harder to share |
How Major Platforms Generate Slugs
Different platforms take different approaches to automatic slug generation. Understanding these patterns helps you choose the right approach for your own projects.
WordPress
Generates slugs from the post title. Converts to lowercase, replaces spaces with hyphens, and strips most special characters. Allows manual editing. Appends -2, -3, etc. for duplicates. Example: "My First Blog Post" becomes my-first-blog-post.
Medium
Uses the article title followed by a unique hash. Example: my-first-blog-post-a1b2c3d4e5f6. The hash ensures uniqueness but makes the URL longer. The slug portion is editable before publishing.
GitHub
Repository names serve as slugs and are restricted to alphanumeric characters, hyphens, and dots. Repository names are case-insensitive. GitHub Pages uses the filename (without extension) as the slug for generated pages.
YouTube
Uses randomly generated 11-character IDs (e.g., dQw4w9WgXcQ) rather than slugs. The video title appears as a query parameter for readability but is not part of the canonical URL. YouTube handles (/@username) use slug-like custom names.
Internationalization: Handling Non-Latin Characters
One of the biggest challenges in slug generation is handling text in non-Latin scripts such as Chinese, Arabic, Japanese, Korean, Cyrillic, and languages with accented characters. There are two main approaches:
1. Transliteration (Romanization)
Convert non-Latin characters to their closest ASCII equivalents. Accented characters like "cafe" become "cafe", German "Strasse" stays "strasse", and Russian text is romanized. This produces universally compatible slugs but loses the original script.
Example: "Uber uns" (About us in German) becomes uber-uns
2. Internationalized Resource Identifiers (IRIs)
Modern browsers support Unicode characters directly in the address bar. A Japanese page can use a slug like /blog/programming-basics in Japanese characters. While this is more user-friendly for non-English speakers, the raw URL contains percent-encoded bytes that can be very long and hard to share in text form.
Trade-off: IRIs look great in the browser but become unreadable when copy-pasted as plain text.
Our slug generator uses the transliteration approach: it normalizes Unicode characters using NFD decomposition, strips combining diacritical marks, and removes any remaining non-ASCII characters. This ensures the output is a clean, universally compatible ASCII slug that works in every browser, email client, and messaging platform.
Worked Example: From Article Title to Perfect Slug
Let us walk through the step-by-step process of turning a real article title into an optimized URL slug.
Original title: "10 Essential Tips for Building Your First React Application in 2025!"
Step 1 - Lowercase: "10 essential tips for building your first react application in 2025!"
Step 2 - Remove special chars: "10 essential tips for building your first react application in 2025"
Step 3 - Remove stop words: "10 essential tips building first react application 2025"
Step 4 - Replace spaces with hyphens: "10-essential-tips-building-first-react-application-2025"
Step 5 - Shorten (optional): Focus on the primary keyword and intent.
Final slug: essential-tips-first-react-app
The automated output from Step 4 is perfectly valid, but manually shortening to 4-5 words in Step 5 produces a tighter, more memorable URL. The best practice is to let the generator handle the technical cleanup (lowercasing, removing special characters, hyphenating) and then manually review the result for length and keyword focus.
Common Slug Patterns
Different content management systems and frameworks follow different slug conventions. Blog platforms typically generate slugs from the post title, producing patterns like /blog/how-to-improve-seo. E-commerce sites often combine category and product name, such as /shoes/running-shoes-men. Documentation sites may use versioned paths like /docs/v2/getting-started. News outlets sometimes include dates for chronological context, resulting in patterns like /2025/03/market-update. Regardless of the pattern, the core principles remain the same: be concise, be descriptive, and keep it consistent across your entire site. Our slug generator handles all the heavy lifting by automatically lowercasing text, stripping accents and special characters, and replacing spaces with hyphens to produce clean, SEO-ready slugs every time.
301 Redirects: What to Do When You Change a Slug
Changing a URL slug after a page has been published and indexed can cause serious SEO and user experience problems. Every inbound link, bookmark, and search engine index entry points to the old URL. Without a redirect, those all become broken 404 pages.
- Always use a 301 (Permanent) redirect. A 301 tells search engines that the page has moved permanently and that link equity should be transferred to the new URL. A 302 (Temporary) redirect does not pass full link equity.
- Update internal links. After setting up the redirect, update all internal links across your site to point directly to the new URL. Redirect chains (A redirects to B redirects to C) slow down page loads and dilute link equity.
- Submit the updated sitemap. Regenerate and submit your XML sitemap in Google Search Console so search engines discover and index the new URL faster.
- Monitor for 404s. Use Google Search Console or a log analysis tool to verify that no pages are returning 404 errors after the change.
