How to tag X (Twitter) links
Tags cost nothing on X
X wraps every link in t.co and counts it as 23 characters, so a long tagged link takes up no more room than a short one.
Always add utm_medium=social
GA4's list of social sites has twitter and t.co but not x. With utm_medium=social, a visit tagged utm_source=x still lands in Organic Social.
For ads, use twitter
GA4 files Paid Social only when the source is on its social list. For X ads, use utm_source=twitter with a paid medium; for posts, x is fine.
Example: An X post linking to a product page = https://example.com/new?utm_source=x&utm_medium=social&utm_campaign=launch

Reference
Where links work on X, and how to tag them
Every place a link can sit on X, whether people can click it, and the tag to give it.
| Where the link sits | Clickable? | Tag to add |
|---|---|---|
| Posts | Clickable, shown through t.co | utm_medium=social |
| Replies | Clickable | utm_content=reply |
| Bio website | Clickable | utm_content=bio |
| Ads | Clickable | utm_source=twitter, utm_medium=paid-social |
Mydrop's campaigns write utm_source=x for X. If your reports already use twitter, keep twitter: what matters is using one name everywhere.

X links, tagged automatically by Mydrop
