What makes a good URL slug?

A good slug is lowercase, uses hyphens between words rather than spaces or underscores, contains only letters, numbers and hyphens, and is short enough to read at a glance. That keeps URLs tidy, shareable and friendly for both people and search engines.

What happens to accents and non-English letters?

Accented letters are converted to their closest plain equivalent, so "café crème" becomes "cafe-creme". This keeps slugs working reliably in links and file systems, where unusual characters can be encoded into something unreadable.

Why hyphens instead of underscores?

Search engines treat hyphens as word separators but tend to read underscores as joining words together, so "url-slug" is seen as two words while "url_slug" can be read as one. Hyphens are the long-standing convention for clean, readable web URLs.
