This article is a stub.

Invisible data or metadata for that matter is undesirable. The general problem with invisible data is that being invisible, nobody sees when it's wrong. If something is wrong on a web page and it's visible, a visitor can see it, a page author (without technical abilities) can see it. Invisible data doesn't get seen and errors inside it are not found as easily as visible data is.

See Principles of visibility and human friendliness.

Also known as, "dark data", "meta tags", "side files".
