What Are UTM Parameters?
UTM (Urchin Tracking Module) parameters are tags you add to URLs to track the performance of marketing campaigns. When someone clicks a link with UTM parameters, analytics tools like Google Analytics can identify exactly where that traffic came from and what campaign drove it.
Think of UTM parameters as digital fingerprints for your marketing efforts. They answer critical questions like:
- Which social media platform drives the most qualified traffic?
- What type of messaging resonates best with your audience?
- Which campaigns are actually driving revenue, not just clicks?
- How do different audience segments respond to your offers?
Example UTM-Tagged URL
https://demandlinks.com/signup?
utm_source=linkedin&
utm_medium=social&
utm_campaign=product_launch_2024&
utm_content=founders_video&
utm_term=marketing_analyticsThis URL tells us the traffic came from LinkedIn, it's social media traffic, part of the 2024 product launch campaign, specifically from a video targeted at founders about marketing analytics.
The 5 UTM Parameters Explained
There are five UTM parameters, but only three are required. Understanding when and how to use each one is crucial for effective campaign tracking.
1. utm_source (Required)
What it tracks: Where the traffic is coming from (the referrer)
This is the most important parameter. It identifies the platform, website, or source that's sending traffic to your site.
Best Practices for utm_source:
- Be specific: Use "linkedin" not "social"
- Be consistent: Always use "google" not sometimes "Google" or "google.com"
- Use lowercase: Avoid capitalization inconsistencies
- No spaces: Use underscores or hyphens instead
✓ Good Examples
- email_newsletter
- partner_website
✗ Bad Examples
- LinkedIn (capitalized)
- google.com (too specific)
- social media (too generic)
- email newsletter (spaces)
- partner site (inconsistent)
2. utm_medium (Required)
What it tracks: The marketing medium or channel type
This parameter categorizes the general type of marketing channel. It's broader than utm_source and helps you understand which types of marketing are most effective.
Standard utm_medium Values:
organic- Organic search resultscpc- Cost-per-click ads (Google Ads, etc.)social- Social media postsemail- Email campaigns
referral- Links from other websitesdisplay- Banner/display advertisingaffiliate- Affiliate marketingdirect- Direct traffic (rarely used)
3. utm_campaign (Required)
What it tracks: The specific campaign or promotion
This is where you identify the specific marketing campaign, product launch, or promotion. It's the most flexible parameter and where you can get creative with your tracking strategy.
Campaign Naming Strategies:
Date-Based:
product_launch_2024_q1, black_friday_2024
Goal-Based:
awareness_campaign, lead_generation, retention_push
Product-Based:
analytics_tool_launch, premium_upgrade_promo
4. utm_content (Optional)
What it tracks: Specific ad creative, link, or content piece
Use this parameter to differentiate between different ads, emails, or content pieces within the same campaign. It's perfect for A/B testing and understanding which creative elements perform best.
utm_content Use Cases:
- A/B Testing: video_ad_v1, video_ad_v2, text_ad_v1
- Email Sections: header_cta, footer_link, sidebar_banner
- Ad Variations: founders_testimonial, product_demo, pricing_focus
- Content Types: blog_post, case_study, whitepaper
5. utm_term (Optional)
What it tracks: Paid search keywords or audience targeting
Originally designed for tracking paid search keywords, utm_term has evolved to track any targeting criteria including audience segments, demographics, or interests.
Modern utm_term Applications:
- Keywords: marketing_analytics, utm_tracking, campaign_attribution
- Audiences: startup_founders, marketing_managers, enterprise_clients
- Demographics: age_25_34, location_usa, industry_saas
- Interests: digital_marketing, data_analytics, growth_hacking
UTM Naming Conventions That Scale
Consistent naming conventions are the difference between actionable insights and data chaos. Here's a framework that scales from startup to enterprise.
The Golden Rules
- 1Always use lowercase: Prevents duplicate entries in analytics
- 2Use underscores, not spaces: Ensures URLs work properly
- 3Be descriptive but concise: Balance clarity with brevity
- 4Document your conventions: Share with your team
- 5Review and clean regularly: Maintain data quality
Example Naming Convention Framework
utm_source
Platform or website name (lowercase, no spaces)
utm_medium
Marketing channel type (standardized list)
utm_campaign
goal_product_timeframe or similar structure
7 UTM Mistakes That Kill Your Data
These mistakes are more common than you think, and they can completely undermine your marketing attribution. Here's how to avoid them.
Mistake #1: Inconsistent Capitalization
Using "LinkedIn", "linkedin", and "LINKEDIN" creates three separate sources in your analytics.
Mistake #2: Using Spaces Instead of Underscores
Spaces in URLs get encoded as %20, making your UTMs unreadable and potentially breaking links.
Mistake #3: Overly Generic Parameters
Using vague terms like "social" for utm_source doesn't give you actionable insights.
Mistake #4: Not Using UTMs on Internal Links
Email campaigns and internal promotions need UTMs too, or you'll lose attribution.
- • Email newsletter links
- • Internal banner ads
- • Push notification links
- • SMS campaign links
