The website=* tag can be used to provide the full URL to the official website for the related features, be it a building, park railway or anything else. A link to a relevant but unofficial alternative or additional resource can be created using url=*. A link to Wikipedia should use wikipedia=* (do however note the different format for wikipedia links which are not full URLs).

For small format websites (designed for smaller displays, reduced bandwidth, or mobile touchscreens) use website:mobile=*.

Avoid long URLs

Use as short an URL as possible. Choose simple URLs over complex URLs if they basically point to the same content. For example, use instead of, as both will get you to the front page. Websites are frequently redesigned, so strive for the most "robust" URL that works.
