The URL Slug is the last part of the page's public address: https://your-site/pages/<slug> for pages and https://your-site/blog/<slug> for blog posts. While you type the Title, the slug is generated automatically: the text is lower-cased, punctuation is replaced by spaces and spaces become dashes (e.g. "Our Story!" → our-story). You can overwrite it manually; on save it is cleaned the same way.

Rules:

• It must be unique within pages (or within blog posts). Saving with a slug already used shows "Url Exists in other post: <title>".
• For blog posts the slug is mandatory ("Url empty").
• A page with an empty slug is the website's home page when your theme is set to use a CMS page as home.
• The slugs terms and privacy are reserved for the Terms & Conditions and Privacy Policy pages.
