Common UTM fields
Typical fields include utm_source, utm_medium, utm_campaign, utm_term, utm_content, and utm_id. They tell analytics systems where a click came from and which campaign or creative produced it.
Advertising platforms also use click identifiers such as gclid, fbclid, msclkid, and related values.
Privacy and link-sharing concerns
A tracking parameter can reveal the newsletter, advertisement, campaign, or account flow that produced the link. Some sites also place email, user, referral, or session identifiers in the query string.
URLs are commonly stored in browser history, analytics logs, chat systems, screenshots, referrer data, and support tickets.
What can be removed safely
Known campaign and click identifiers are often removable without changing the destination. Unknown parameters may control search filters, language, document selection, or access, so keep them until tested.
Signed URLs and invitation links can function like credentials. Do not publish them merely because they lack a recognizable tracking field.
Test the cleaned URL
Open the cleaned link in a private window and confirm the correct page appears. Check whether login, document access, filters, or checkout state changed.
When sharing publicly, remove unnecessary fragments, referral values, email fields, and account identifiers as well as UTM tags.
Final review checklist
- Common UTM and click IDs removed
- Unknown parameters reviewed
- Signed or invite links kept private
- Clean link tested
- Remaining path and query identifiers checked
