What is a URL slug?
A URL slug is the readable part of a web address that identifies a page — the "how-to-write-a-slug" in example.com/blog/how-to-write-a-slug. It uses real words instead of a database ID or query string, so people and search engines can tell what a page covers before they click. A slug generator turns any title, heading, product name, or phrase into that clean, URL-safe string automatically.
This tool converts your text into a slug instantly and runs entirely in your browser — nothing is uploaded. You choose the separator, whether to lowercase, and whether to drop common stop words.
Who is the slug generator for?
- Bloggers and content writers — slugify post titles and section headings.
- E-commerce and marketing teams — slugify product, category, and campaign names.
- Developers and site owners — generate URL-safe identifiers for routes, files, tags, and database records.
- Documentation authors — turn headings into anchor links.
Anywhere text becomes part of a URL, a clean slug helps people and search engines read it.
How to use the slug generator
- Type or paste any text — a title, heading, product name, or tag.
- The slug appears instantly — accents stripped (café becomes cafe), punctuation removed, spaces replaced by your separator.
- Adjust the options: hyphen or underscore, lowercase on or off, and optional stop-word removal.
- Copy the slug into your CMS, your code, or wherever the URL lives.
What makes a good, SEO-friendly slug
Short, descriptive, and keyword-focused wins. Google's own URL structure guidelines recommend simple, human-readable URLs. In practice:
- Keep it short — aim for under about 60 characters and three to five words.
- Include the main keyword or the name of the thing the page is about.
- Use lowercase to avoid duplicate URLs on case-sensitive servers.
- Separate words with hyphens (more on that below).
- Skip stop words, dates, and IDs that add length without meaning.
A slug like "wireless-earbuds-pro" or "beginners-guide-open-source" reads and ranks better than a long, padded string.
Hyphens vs. underscores, and stop words
Google treats a hyphen as a space between words but reads an underscore as a joiner, so "open-source" is understood as two words while "open_source" can be read as one. That's why hyphens are the SEO-preferred separator for public URLs; underscores mostly belong in code. Removing stop words ("a," "the," "of") is optional — it shortens the slug, but keeping them is fine when they aid readability. This generator never lets stop-word removal leave you with an empty slug.
Slug mistakes to avoid
- Changing a live slug without a redirect — add a 301 so existing links and ranking carry over.
- Keyword stuffing — repeating a term doesn't help and looks spammy.
- Dates and version numbers — they age the URL and undercut evergreen content.
- Uppercase letters or spaces — both cause inconsistent, hard-to-share links.
