Slug Generator

Convert text into clean, URL-friendly slugs for your website or blog.

What Is a URL Slug?

A URL slug is the part of a web address that identifies a specific page in a human-readable format. For example, in the URL example.com/my-blog-post-title, the slug is my-blog-post-title.

Slugs are created by converting a title or phrase into a lowercase, hyphen-separated string that contains only letters, numbers, and hyphens. Special characters, spaces, and punctuation are removed or replaced.

Why Are Slugs Important for SEO?

  • Search engine ranking — Google considers URL structure as a ranking factor. Clean, descriptive URLs perform better than random IDs or query strings.
  • User experience — Readable URLs help users understand what a page is about before clicking. /how-to-learn-python is far more informative than /post?id=48273.
  • Link sharing — Clean slugs look professional when shared on social media, emails, and messaging apps.
  • Accessibility — Screen readers can interpret well-formed slugs more effectively than encoded special characters.

Best practice: Keep slugs short, descriptive, and keyword-rich. Avoid stop words (a, the, is, and) when possible. Use hyphens, not underscores — Google treats hyphens as word separators but underscores as word joiners.

How Our Slug Generator Works

  1. Lowercase conversion — All letters are converted to lowercase for consistency.
  2. Special character removal — Punctuation, symbols, and non-alphanumeric characters are stripped.
  3. Space replacement — Spaces and consecutive whitespace are replaced with a single hyphen.
  4. Trim — Leading and trailing hyphens are removed for a clean result.

Frequently Asked Questions

What characters are allowed in a slug?

Our generator produces slugs containing only lowercase letters (a-z), digits (0-9), and hyphens (-). This is the safest, most universally compatible format for URLs across all web platforms and CMS systems.

Should I use hyphens or underscores in slugs?

Use hyphens (-). Google officially recommends hyphens over underscores because their algorithm treats hyphens as word separators. The URL my-page is interpreted as “my page,” while my_page is treated as a single word “mypage.”
