Key:website - OpenStreetMap Wiki

The website=* tag is used to provide the full URL to the official website for the related feature.

Format

Website URLs usually follow the syntax:

http(s)://(www.)domain.tld(/)(page)(?parameters)(#anchor), where parts in parenthesis may be optional.

Example

website=https://www.openstreetmap.org - validly formatted direct link to a trustworthy website.

Best practices

Durability and machine-readability

• Take care when copying links from a search engine result. Search results URLs hide information about the final destination of the link, and are not meant for permanent linking. https://encrypted.google.com/url?sa=t&rct=j&q=&esrc=s...

• Prefer websites with domain names. URLs containing IP addresses tend to become outdated more quickly than URLs with domain names and are far less recognizable. This Sophox query finds websites at IPv4 addresses.

Usability

• If the official website is available in multiple languages depending on the URL, link to the version in the locally appropriate language or the language-neutral version. (Some websites automatically redirect to the user's language if you omit a language code from the URL.)

• website=* is only for official websites, not for general web links. Use wikipedia=* for Wikipedia articles. Social media profiles are tagged using contact:*=* keys: contact:mastodon=*, contact:facebook=*, contact:twitter=*, etc. If a social media web presence is the only web presence of the feature, some prefer to also list the URL using website=* to indicate that no other official website exists. (Do not use bulk edits to "deduplicate" the website and contact tags)

Privacy and security

• Remove any tracking parameters (mc_id, utm_source, utm_medium, utm_term, utm_content, utm_campaign, (and other utm_*), fbclid^[1], gclid, campaign_ref, gclsrc^[2], dclid^[3], WT.tsrc, wt.tsrc^[4], zanpid, yclid^[5], igshid^[6] etc.). For example, something like http://paris.intersquat.org/les-lieux/le-satellite/?fbclid=de58e340d6aa79a584552a2055042d004b9b19454bc0d7a6046fc81fc90f51 should be replaced by http://paris.intersquat.org/les-lieux/le-satellite
