URL Slug vs Permalink: What’s the Difference?
The main difference between a URL slug and a permalink is that a permalink is the full URL, while a slug is just the last part of it.
This guide explains both concepts in a simple way with examples.
What is a Permalink?
A permalink (short for "permanent link") is the complete URL of a webpage. It is designed to remain unchanged over time.
Example:
https://example.com/blog/what-is-a-slug
This entire URL is the permalink.
What is a URL Slug?
A URL slug is the last part of the URL that identifies a specific page.
Example:
Permalink: https://example.com/blog/what-is-a-slug
The slug is: what-is-a-slug
