How to set up UTM links for influencer campaigns in Google Analytics 4
UTM links are the difference between knowing which creator drove which sale and guessing. They take 5 minutes to set up correctly and save weeks of post-campaign attribution confusion. Here is the exact structure to use.
The correct UTM parameter structure for influencer campaigns
A UTM link for influencer marketing should use four parameters consistently:
utm_source: The platform where the post appears. Use: instagram, tiktok, youtube, twitter. Keep lowercase and consistent - "Instagram" and "instagram" appear as separate sources in GA4.
utm_medium: The channel type. Use: influencer (not "social" - this lets you separate influencer traffic from organic social and paid social in your reports).
utm_campaign: Your campaign identifier. Use a consistent naming convention like: q2-2026-beauty-micro. Include quarter, year and campaign type at minimum.
utm_content: The specific creator identifier. Use: their handle without the @ symbol. This is how GA4 shows you which creator drove which traffic.
Example full UTM URL:https://yourbrand.com/product?utm_source=instagram&utm_medium=influencer&utm_campaign=q2-2026-beauty-micro&utm_content=creatorhandle
How to build UTM links without manual errors
Manual UTM link construction creates errors - inconsistent capitalisation, missing parameters, typos in campaign names. Use Google's Campaign URL Builder (search "Google UTM builder") for one-off links. For campaign-scale link generation, KALO IQ generates correctly structured UTM links for each creator automatically when you create a campaign record.
Either way, test every link before sending it to a creator. Click the link, check it routes to the correct landing page and confirm the UTM parameters appear in the URL bar. Then check GA4 the following day to confirm the session appeared under the correct source.

Where creators should place UTM links by platform
Instagram Feed and Reels: No clickable links in captions. Creator adds the UTM link to their bio and references "link in bio" in the caption. Link stickers in Stories (available to all accounts) are the most reliable Instagram placement.
TikTok: Bio link is the most reliable option. Creators add the UTM link to their bio for the campaign duration and reference it in the video.
YouTube: UTM link goes in the video description as the first link. The creator can also pin a comment with the link for the first 48 hours.
Twitter/X: UTM link can go directly in the post. No restrictions on clickable links.
Reading influencer UTM data in GA4
In GA4, go to Reports > Acquisition > Traffic acquisition. Change the primary dimension to "Session source" or "Session campaign" to see your influencer traffic. Filter by utm_medium = influencer to isolate influencer traffic from other sources.
Under "Session campaign" you see each campaign. Drill into utm_content to see per-creator performance. Add the "Conversions" metric to see which creator-specific traffic resulted in purchases or goal completions.
