Slug
also called URL slug
The readable identifier for a page at the end of its URL.
The last part of the web address.
What It Is
Slug is part of Website, and more precisely Platform. The working definition is simple: the readable identifier for a page at the end of its URL.
It is a label with a settled working definition, so the value is in using it the same way every time. Held that way, the term stays useful instead of turning into decoration.
How It's Used
Slug comes up in site builds, page structure and the technical decisions underneath them. In real work it sits close to URL Structure, Collection and Canonical URL. The practical test is whether everyone in the room means the same thing by it.
Why It Matters
Getting Slug wrong is expensive in a quiet way. When it is unclear, the site still launches — it just quietly underperforms. Deciding it deliberately costs one conversation. Leaving it undecided costs several.
It is the short word for a longer explanation. The last part of the web address.
Termshift™
How the meaning shifts depending on who is using it, and where.
Inside the industry, Slug is used tightly and assumed to be understood: the readable identifier for a page at the end of its URL.
Away from the jargon, it is the last part of the web address.
The Bottom Line
Slug is not complicated — it is just often left vague. The last part of the web address. Decide it, write it down, move on.
