What each parameter means

Campaign source utm_source
Where the traffic comes from: a site, platform or publication. Example: google, newsletter, linkedin
Campaign medium utm_medium
The marketing channel. Standard values (cpc, email, social, paid_social, referral, display) let Google Analytics group traffic correctly. Example: cpc, email, social
Campaign name utm_campaign
The specific campaign, promotion or product launch. Example: spring_sale
Campaign ID utm_id
Optional ID that ties the link to a campaign in GA4 or your ad platform. Example: abc123
Campaign term utm_term
The paid search keyword the link is tied to. Example: running_shoes
Campaign content utm_content
Tells apart ads or links that point to the same URL, for example in A/B tests. Example: blue_banner

Best practices

  • Stay consistent

    Analytics tools treat "Facebook" and "facebook" as different values. Pick lowercase names, agree on them as a team, and reuse the same ones.
  • Tag external links only

    Use UTM links for ads, emails, social posts and partner sites. Links between your own pages can overwrite the real traffic source.
  • Keep it private

    UTM values are public. Never put emails, names, tokens or other personal data in them.

Frequently Asked Questions

A UTM link is a normal URL with extra parameters added to the end, such as utm_source, utm_medium and utm_campaign. When someone clicks it, analytics tools like Google Analytics read those parameters and report exactly which campaign, channel and source sent the visit.
