A: A slug is a set of words or numbers used in a URL for a specific webpage, such as https://example.com/this-is-the-slug. The slug is used to identify specific posts or pages.

Slugs are auto-generated based on the title. And as with all web urls, they should (and usually are) be entirely lowercase and not contain spaces. Spaces are usually replaced by a hyphen or underscore. Punctuation marks are generally removed.

Your title can be "This is the title", and your slug would be "this-is-the-title". You can change the slug to "this-is-a-more-keyword-specific-slug". If you don't know what it is, just leave it the way it is generated.
