How this slug generator works
A slug is the human-readable identifier at the end of a URL — the part a reader and a search engine both use to tell what a page is about. A good slug is short, lowercase, and uses real words separated by hyphens, with no spaces, accents or punctuation that browsers would have to encode.
This tool builds each slug in a few predictable steps. First it normalizes and removes diacritics so accented letters become their plain equivalents (é becomes e). Then it replaces every non-alphanumeric character with your chosen separator, collapses repeated separators into one, and trims any leading or trailing separators. Finally it lowercases the result and, if you set a maximum length, trims it without leaving a dangling separator.
| Title | Slug |
|---|---|
| My First Blog Post! | my-first-blog-post |
| Crème Brûlée: My #1 Recipe! | creme-brulee-my-1-recipe |
| 10 Tips & Tricks for SEO | 10-tips-tricks-for-seo |
| The Art of War | the-art-of-war |
| Hello, World — Again | hello-world-again |
Reference note: diacritic removal uses Unicode normalization (NFKD) and strips combining marks. Characters outside the Latin alphabet that have no plain equivalent are removed, so a non-Latin title may produce a short or empty slug.
Frequently asked questions
- What is a URL slug?
- A URL slug is the readable part of a web address that identifies a page — usually the text after the final slash. For a post titled "My First Blog Post" the slug is typically "my-first-blog-post". It is meant to be short, lowercase and human-friendly.
- How do I create an SEO-friendly slug?
- Start from the page title, make it lowercase, remove accents and punctuation, join words with hyphens, and keep it short and descriptive. Optionally drop filler stop-words such as "a", "an", "the", "of", "and" and "or" so the important keywords stand out.
- Should slugs use hyphens or underscores?
- Use hyphens. Google treats hyphens as word separators but reads underscores as joiners, so "my_blog_post" can look like one word while "my-blog-post" reads as three. Hyphens are the recommended default.
- Should slugs be lowercase?
- Yes, lowercase is recommended. URLs can be case-sensitive on some servers, so mixing cases risks duplicate URLs for the same page. Keeping every slug lowercase avoids that and looks cleaner.
- How long should a URL slug be?
- Keep it short — a few descriptive words is ideal, and many teams cap slugs at around 50 to 60 characters. Use the optional maximum-length setting to trim long titles cleanly.
- Do slugs affect SEO?
- A clear, keyword-rich slug helps users and search engines understand a page and can improve click-through from search results. Slugs are one of many signals, but a clean, readable URL is an easy win.
