Top Tips for Clean UTM Tracking
1. Always Use Lowercase
GA4 treats “Facebook” and “facebook” as different sources. Stick to lowercase for everything—source, medium, campaign name. Your reports will thank you.
2. Establish Naming Conventions Early
Before you launch a single campaign, document your standards:
- Source examples: google, facebook, newsletter, linkedin
- Medium examples: cpc, social, email, referral, organic-social
- Campaign format: season-offer-year (e.g., spring-sale-2026)
Consistency prevents your GA4 reports from turning into alphabet soup.
3. Never Tag Internal Links
Adding UTM parameters to links within your own site breaks session tracking. Use them only for external traffic sources—emails, social posts, ads, partner sites.
4. Keep Campaign Names Descriptive
“Campaign1” tells you nothing three months from now. Use names like “q1-email-webinar-series” or “black-friday-retargeting” that explain what you’re tracking.
5. Avoid Special Characters
Spaces, ampersands, and unusual symbols can break tracking. Stick to letters, numbers, and hyphens. Let the tool handle the URL encoding.
6. Review Weekly
Check your GA4 Acquisition reports every week to catch typos and naming inconsistencies before they pollute months of data. One misspelled campaign name can skew your entire attribution analysis.
Common UTM Mistakes to Avoid
Missing the medium parameter — Without it, GA4 can’t categorize your traffic properly. Always specify whether it’s email, social, cpc, or referral.
Overtagging — You don’t need UTM tags on every link. Use them for traffic coming to your site from external sources, not for navigation within your site.
Inconsistent capitalization — “Facebook”, “facebook”, and “FB” all count as separate sources in GA4. Pick one format and stick to it religiously.
