X (formerly Twitter) shows surprising amounts of attribution leakage — links inside threads, replies, DMs, and Twitter Ads all collapse to 't.co / referral' unless you UTM-tag them. The shift from Twitter to X also means most teams now have a mix of utm_source=twitter and utm_source=x in their data — pick one and standardize.
Pick these defaults and lock them in — every X (Twitter) link your team builds will stay consistent and roll up cleanly in reports.

If you're starting fresh, `x` is fine but commit to one.
No. X wraps your URL in a t.co redirect for click tracking, but the underlying URL with all UTM parameters intact is what the user lands on. Your analytics will see the full UTM string.
`utm_medium=cpc` for paid Promoted Tweets and Promoted Accounts. `utm_medium=social` for organic tweets.
Add utm_content=thread-cta (or utm_content=closing-tweet) to the link in your final tweet. This isolates thread-end traffic so you can measure whether your closing matters.
Yes. Use utm_medium=dm (instead of social) for links you send in DMs. This separates outbound effort from organic feed traffic.
