What is Slug?

A slug is the human-readable, URL-friendly part of a web address that identifies a page — for example "my-first-post" in /blog/my-first-post. Slugs are lowercase, use hyphens instead of spaces, and strip special characters.

Good slugs improve readability and SEO. They are typically generated from a title by lowercasing, removing accents, and replacing non-alphanumeric characters with hyphens.
