URL means Uniform Resource Locator. It can stand for a variety of things while mappers mostly use it for websites.

This tag is being used for very different types of content - official websites of an amenity or its operator, third-party pages, the object's Wikipedia entry, photographs featuring the object, or even documentation on the OSM wiki. So it is advised not to use this tag when more specific alternatives are available such as website=* (or its synonym contact:website=*), facebook=* (or its synonym contact:facebook=*), twitter=* (or its synonym contact:twitter=*), image=*, wikipedia=* and so on.
