When someone clicks a UTM-tagged link, Google Analytics records these parameters, letting you see exactly which campaigns drive traffic and conversions.

What are UTM Parameters?
UTM (Urchin Tracking Module) parameters are tags added to URLs that help track the effectiveness of marketing campaigns. When someone clicks a link with UTM parameters, the data is sent to your analytics platform, allowing you to see exactly where your traffic comes from.
There are five standard UTM parameters: source (where traffic comes from), medium (the marketing medium), campaign (the specific campaign name), term (paid keywords), and content (differentiate similar content).

UTM Best Practices for 2026
Use Consistent Naming
Stick to lowercase letters and use underscores or hyphens instead of spaces. "facebook" not "Facebook" or "FACEBOOK". Inconsistent naming creates separate entries in analytics.
Be Specific with Campaign Names
Include date or quarter in campaign names for easier tracking: "spring_sale_2026" or "newsletter_jan_2026". This helps when reviewing historical data.
Want to Shorten Your UTM Links?
Long UTM URLs look messy. Create a free TrimLink account to shorten your campaign links and track clicks with built-in analytics.
Document Your Conventions
Create a UTM naming guide for your team. Define allowed values for source, medium, and campaign to maintain consistency across all marketing efforts.
Don't Use UTM on Internal Links
Only use UTM parameters for external traffic sources. Using them on internal links will break session tracking and inflate your traffic numbers.
Common UTM Mistakes to Avoid
Inconsistent Capitalization
"Facebook" and "facebook" show as different sources. Always use lowercase.
Missing Parameters
Always include source, medium, and campaign. Missing parameters make tracking incomplete.
Vague Campaign Names
"promo" tells you nothing. Use "summer_sale_2026_email" for clarity.
Using Spaces
Spaces become %20 in URLs. Use underscores or hyphens instead.
