A slug generator converts any title or phrase into a clean, URL-friendly slug — the readable part of a web address. For example, “How to Bake Bread” becomes how-to-bake-bread. Good slugs improve SEO, readability, and click-through rates. This guide explains what a URL slug is, how to create one step by step, the rules for SEO-friendly slugs, and common mistakes to avoid.
Short answer: To create a slug online, paste your title into a free URL slug maker tool. The tool lowercases the text, replaces spaces with hyphens, removes special characters, and gives you a clean slug instantly.
What Is a URL Slug?
A URL slug is the human-readable part of a web address that identifies a specific page. In example.com/blog/how-to-bake-bread, the slug is how-to-bake-bread.
Slugs matter for two reasons. First, Google uses them as a ranking signal — keywords in the slug help search engines understand what the page is about. Second, humans glance at URLs before clicking. A clean slug like how-to-bake-bread builds trust; a messy one like page.php?id=1234&x=2 does not.

A slug maker automates the conversion: it takes any title, strips out everything that doesn’t belong in a URL, and returns a clean result. Doing this by hand for twenty blog posts in a row is tedious — especially when titles contain apostrophes, accented characters, or special punctuation. You can convert slug text in bulk just as easily as one at a time.
How to Create Slugs Online
Follow these steps:
- Step 1: Open the free tool. Go to the URL slug maker. No signup needed. The slug name you generate works anywhere URLs are used.
- Step 2: Paste your title. Type or paste any text — a blog post title, product name, page heading, or category label.
- Step 3: Choose your separator. Hyphens are the SEO convention for URLs. Underscores work better for filenames and code identifiers.
- Step 4: Set your options. Enable lowercase (recommended), accent removal, and optionally stop-word removal for shorter slugs. Set a max length if your system enforces one.
- Step 5: Copy the result. Click Copy and paste the slug into your CMS, website builder, router, or database.
Worked example:
Input: How to Use SQL — A Beginner’s Guide (2026 Edition)
Output: how-to-use-sql-a-beginners-guide-2026-edition
The em dash, parentheses, apostrophe, and capitalization all get cleaned up automatically.
What Makes a Good URL Slug?
| Rule | Good Example | Bad Example |
|---|---|---|
| Lowercase only | bake-bread | Bake-Bread |
| Hyphens, not underscores | bake-bread | bake_bread |
| No spaces | bake-bread | bake bread |
| No special characters | cafe-au-lait | café-au-lait |
| No stop words | bake-bread | how-to-bake-a-loaf-of-bread |
| Contains primary keyword | how-to-bake-bread | page-1234 |
| Under 60 characters | convert-svg-to-png | complete-guide-to-converting-svg-vector-files-to-png-images |
Why hyphens beat underscores: Google treats hyphens as word separators but sees underscores as part of the word itself. bake-bread reads as two words; bake_bread reads as one. Always use hyphens in URL slugs.
Why lowercase matters: Some servers are case-sensitive. Bake-Bread and bake-bread can be treated as different URLs, causing 404 errors or duplicate content. Lowercase everything.
Slug Transformation Examples
| Original Text | Generated Slug |
|---|---|
| Hello World! | hello-world |
| 10 Best Tips & Tricks | 10-best-tips-tricks |
| Café with Crème Brûlée | cafe-with-creme-brulee |
| What is SEO? A Guide | what-is-seo-a-guide |
| Product Name [2024] | product-name-2024 |
Notice how a slug creator handles each problem: exclamation marks disappear, ampersands are dropped, accented characters become their plain equivalents (é→e, ü→u), question marks vanish, and brackets are stripped.
When to Use This Tool
Blog posts and articles. Generate the slug before publishing so the page URL is clean, readable, and consistent. Most CMS platforms auto-generate slugs, but a dedicated slug online tool gives you more control over stop words and length.
Product and category pages. E-commerce platforms often ask you to enter a URL slug separately from the product name. A URL slug generator gets the format right without manual editing.
Batch migrations. When setting up a website or migrating content, you may need slugs for dozens of page titles at once. A bulk slug generator handles the whole list in seconds.
File and folder names. The same slugify logic works for creating URL-safe file names, folder names, and anchor IDs for in-page navigation.
Common Mistakes to Avoid
Using underscores instead of hyphens. This is the most common slug mistake. Google explicitly recommends hyphens. Underscores make your slug harder for search engines to parse.
Keeping stop words. Words like “a,” “the,” “and,” and “in” add length without meaning. how-to-bake-bread is better than how-to-bake-a-loaf-of-bread. Remove them unless they change the meaning.
Making slugs too long. Aim for under 60 characters. Long slugs get truncated in search results and are harder to share. If your title is long, keep only the core keywords.
Including dates in evergreen content. best-recipes-2024 looks outdated in 2026. Only include dates when the content is genuinely time-specific.
Using generic slugs. post-123, page-2, and untitled tell nobody anything. Always use descriptive, keyword-rich slugs.
Changing slugs without redirects. If you update an existing page’s slug, the old URL breaks. Always set up a 301 redirect from the old slug to the new one.
Frequently Asked Questions
What is a slug in SEO?
A slug in SEO is the readable portion of a URL that describes the page content, like how-to-bake-bread in example.com/blog/how-to-bake-bread. Search engines use slugs as a ranking signal, and descriptive slugs improve click-through rates because users can see what the page is about before clicking.
Why are hyphens better than underscores in slugs?
Google treats hyphens as word separators but considers underscores part of the word. bake-bread is read as two words (“bake” and “bread”), while bake_bread is read as one word (“bake_bread”). Hyphens make URLs more readable for both users and search engine crawlers.
Should I remove stop words from my slugs?
Yes, generally. Removing words like “a,” “the,” “and,” and “in” keeps URLs short, descriptive, and focused on primary keywords. bake-bread-recipe is cleaner than a-recipe-for-how-to-bake-bread. Keep stop words only if removing them changes the meaning.
What is slugify?
To slugify means to convert text into a URL-safe slug format: lowercase the text, replace spaces with hyphens, remove special characters and accents, and strip unnecessary words. A slugify URL tool automates this process.
How long should a URL slug be?
Aim for under 60 characters. Shorter slugs are easier to read, share, and display fully in search results. Include your primary keyword near the beginning and cut everything that doesn’t add meaning.
Can I use numbers in slugs?
Yes, when they’re meaningful. top-10-recipes is fine because “10” is part of the content promise. Avoid meaningless numbers like page-2 or auto-generated IDs — they add nothing for SEO or users.
