Free tool
LinkedIn UTM Builder.
Tracking URLs for LinkedIn Ads, built the same way every time. Source and medium are fixed so the traffic lands in the right GA4 channel group, and campaign names are normalised so one typo does not split a campaign in two.
Why the source and medium are not editable
Every URL this tool builds carries utm_source=linkedin and utm_medium=paid_social. That pair is what GA4 reads to file the session under Paid Social. Swapping in cpc, or letting each person type their own, is the single most common reason a LinkedIn campaign shows up spread across three channel groups in reporting.
What goes where
utm_campaign holds the campaign name, utm_id the LinkedIn campaign ID (which is what lets you join platform cost to session data later), utm_content the ad group or audience, and utm_term the ad format.
