|Tools for this tag|
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.
For small format websites (designed for smaller displays, reduced bandwidth, or mobile touchscreens) use website:mobile=*.
Websites URL usually follow this syntax :
http(s)://(www.)domain.tld/(page)(?parameters)(#anchor), where parts in parenthesis may be optional.
https://www.openstreetmap.org/help would be a good website URL. Its format is valid, it's a direct link to the wanted ressource and a trustworthy website.
- www.openstreetmap.org/help The scheme (http/https) is missing
- http://www.bahn.de/p/view/index.shtml When linking to a website homepage, you can usually omit the part after the first '/', as the browser is automatically redirected (here http://www.bahn.de/). Also the "short" URL might be more stable as websites are often redesigned and such URL might change.
- https://goo.gl/x1fz3h An URL shortener can be misleading as it hides the real URL, can contain advertisements or even malware. The "direct" URL to the website should be used.
- https://encrypted.google.com/url?sa=t&rct=j&q=&esrc=s... Search results URL also hides information about the final destination of the link, and are not meant for permanent linking.
- http://openstreetmap.org/help . The HTTPS version of a website should be used when available, as it enhances security and privacy for users.
