Understanding UTM Parameters

You’re investing time and effort into marketing your website – social media posts, email newsletters, online ads, guest blogging, and more. But when traffic arrives on your site, how do you truly know which specific effort drove that visit? Was it the link in your Twitter bio, the latest email blast, or a paid ad campaign?

If you’re squinting at your analytics dashboard, trying to guess the source, you’re missing out on crucial insights. The key to unlocking this mystery is UTM parameters.

Whether you’re using Google Analytics, Adobe Analytics, Matomo, Umami, or virtually any other standard web analytics platform, understanding and using UTM parameters is fundamental for effective marketing tracking and analysis.

What Exactly Are UTM Parameters?

UTM stands for Urchin Tracking Module. It’s named after Urchin Software Corporation, the company Google acquired that laid the groundwork for Google Analytics.

In simple terms, UTM parameters are short text codes that you add to a URL to track the performance of a specific marketing campaign. When a user clicks a link with UTM parameters, those parameters are sent to your website. Your analytics tracking code reads these parameters and attributes the visit to the source, medium, and campaign you specified.

This allows your analytics platform to give you a clear, detailed breakdown of where your traffic is originating, far beyond just knowing “Social Media” or “Referral.”

Parameters

There are a total of five UTM parameters. You can collect very detailed information using these parameters. Three of these parameters are required, while the other two are optional parameters.

The Core UTM Parameters

These are the three required(¹) parameters:

1- The Source (utm_source)

• Required
• Identifies the specific source of the traffic. Think of where the click originated.
• Examples: google, facebook, twitter, linkedin, newsletter, instagram, bing, youtube.
• Usage Example: utm_source=linkedin

2- The Medium/Channel (utm_medium)

• Required.
• Identifies the marketing medium or channel. Think of how the user got to your site.
• Examples:cpc (cost per click – for paid search/ads), organic (organic search – though often automatically detected), social (social media), email (email newsletter), referral (referral links from other sites), display (display ads), qr_code.
• Usage Example: utm_medium=social

3- The Campaign (utm_campaign)

• Required.
• Identifies a specific marketing campaign or promotion. This helps you group visits from different sources and mediums that are part of the same overall effort. Think of why this link exists.
• Examples:spring_sale_2024, product_launch, april_newsletter, linkedin_profile_link, holiday_promo.
• Usage Example:utm_campaign=linkedin_profile

Optional UTM Parameters for More Details

These two parameters offer additional detail but are not always necessary for basic tracking:

4- The Term (utm_term)

• Mainly used for tracking keywords in paid search campaigns (especially useful if not using auto-tagging).
• Usage Example:utm_term=womens+running+shoes

5- The Content (utm_content)

• Used to differentiate between multiple links or ads pointing to the same URL within the same campaign. Useful for A/B testing headlines, banners, or link placement.
• Usage Example:utm_content=banner_top, utm_content=textlink_sidebar

How to Construct a URL with UTM Parameters

Adding UTM parameters is straightforward:

1. Start with your base URL (the page you want users to land on).
2. Add a question mark (?) to the end of the base URL.
3. Add your first UTM parameter in the format parameter_name=value.
4. For each subsequent parameter, add an ampersand (&) followed by the next parameter in the parameter_name=value format.

Example Base URL: https://yourwebsite.com/product/awesome-gadget

Example URL with UTMs: https://yourwebsite.com/product/awesome-gadget?utm_source=facebook&utm_medium=social&utm_campaign=spring_sale&utm_content=image_ad

When someone clicks this link, your analytics platform will record a visit to the Awesome Gadget page, identifying the source as Facebook, the medium as social, the campaign as spring_sale, and the specific content as the image ad.

Why UTM Parameters Are Essential for Any Marketer

Implementing UTM tracking is a game-changer for understanding your marketing performance:

1. Accurate Attribution: Stop guessing! Know precisely which platforms, websites, or emails are sending you traffic.
2. Measure ROI: By connecting traffic source data to conversions (sales, sign-ups, etc.), you can calculate the return on investment for specific marketing efforts.
3. Identify Top-Performing Channels: Easily see which mediums and sources are most effective in driving not just traffic, but valuable actions on your site.
4. Optimize Campaigns: Use the data to refine your messaging, channel selection, and budget allocation for future campaigns.
5. Granular Insights: Understand performance differences even within the same channel (e.g., comparing two different links in an email newsletter using utm_content).

Best Practices for Using UTMs

To get the most out of your UTM tagging:

• Be Consistent: Develop a standard naming convention (e.g., always lowercase, use underscores or hyphens instead of spaces). facebook is different from Facebook to some systems.
• Use the Core Three: Always include utm_source, utm_medium, and utm_campaign.
• Be Specific: Use descriptive values that you and your team will understand later.
• Avoid Internal Links: Don’t use UTMs for links within your own website. This can overwrite valuable session data.
• Use a URL Builder: Tools like Google’s Campaign URL Builder or others available online can help you build consistent URLs and avoid typos.
• Keep Track: Maintain a spreadsheet or document listing the UTM parameters you’ve used for different campaigns.

UTM Parameters Across Analytics Platforms

The beauty of UTM parameters is that they are an industry standard. Whether you are using a free tool like Google Analytics, a robust enterprise solution like Adobe Analytics, or a privacy-focused alternative like Matomo or Umami, these platforms are designed to read and interpret UTM parameters automatically. They will typically present this data clearly in reports on traffic sources, campaigns, and acquisition channels.

In short

If you’re not already using UTM parameters, you’re flying blind in your marketing efforts. They are a simple yet incredibly powerful tool that provides the data you need to make informed decisions, optimize your spending, and ultimately drive better results for your website.

Start by tagging links you share on social media, in emails, or on other websites. You’ll quickly gain invaluable insights into what’s truly working.

1. Note on “Required” Parameters:
   When we refer to utm_source, utm_medium, and utm_campaign as “required,” we mean they are essential for your web analytics platform (like Umami, Google Analytics, etc.) to properly categorize and report the traffic data in a meaningful way. Technically, a URL with only one or two parameters might still load the page. However, without all three core parameters, the analytics tool will have incomplete information, leading to scattered or misattributed data in your reports. Using all three is the industry best practice for accurate and useful tracking. ↩︎
