How to tag campaign links so your reports stay clean
What each UTM parameter is for
UTM parameters are labels added to the end of a link. Analytics tools read them to tell you where a visit came from.
- utm_source: the site, platform, or sender, such as linkedin, google, or newsletter.
- utm_medium: the type of traffic, such as social, cpc, email, or referral. GA4 uses it to assign the channel.
- utm_campaign: the campaign name. Keep it identical on every channel in the same campaign.
- utm_content: the creative, placement, or call to action, so you can compare variants.
- utm_term: the paid search keyword.
- utm_id: a campaign ID, useful when you import cost data into GA4.
Pick mediums GA4 recognizes
GA4 sorts traffic into default channels using rules on source and medium. A paid medium like cpc, paid-social, or anything starting with paid counts as paid. social, email, referral, affiliate, audio, and sms map to their own channels. A medium GA4 doesn't recognize, like offline or print, usually lands in Unassigned, where it's hard to find later. This builder shows the channel each link is likely to land in.
Naming rules that save a report
Analytics reports treat LinkedIn and linkedin as different values, so one campaign can split into several rows. Agree on a convention before launch and keep it.
- Use lowercase everywhere. This builder can do it for you.
- Use hyphens instead of spaces.
- Never add UTM tags to links between pages on your own site. They overwrite the visit's original source.
- Open one tagged link before launch and check it in GA4's Realtime report.
Frequently asked
Questions, answered.
What people ask before they use the UTM builder.
They're tags added to a link's address, like ?utm_source=linkedin&utm_medium=social. Analytics tools such as GA4 read them to report which source, medium, and campaign sent each visit.
Use source, medium, and campaign on every link. Source is the minimum for a link to be attributed, and without a medium GA4 can't put the visit in the right channel.
In reports, yes. GA4 shows Newsletter and newsletter as separate values, so mixed capitalization splits your data. Keep everything lowercase.
Usually because the medium doesn't match any of GA4's default channel rules. Change it to a standard value such as social, email, cpc, paid-social, referral, or affiliate. The channel estimate in this builder flags it before you launch.
Not when they're on links from other sites, emails, and ads. Keep them off your internal links and point canonical tags at the clean URL so search engines index the page without the tags.
Yes. Switch to Bulk, set the page and campaign once, then add a row per channel. You can copy every link or download a CSV for your launch sheet.
