What is UTM (Urchin Tracking Module)?
UTM stands for Urchin Tracking Module and is used to track where a website’s traffic comes from. When you add a UTM code to the end of a link, analytics tools like Google Analytics or HubSpot can track data on source, campaign, and channel. This provides a clear picture of which initiatives are driving visitors to your site. The name comes from Urchin Software Corporation, which Google acquired in 2005, and the technology was later integrated into the entire modern Analytics ecosystem.
A UTM acts as a small packet of information that travels with the link. You can think of it as a set of labels that you attach to each link so you’ll know later where it was shared. UTMs are especially useful when you want to understand the connection between traffic and campaign efforts across platforms.
How do you use UTM?
You use UTM by adding parameters to a link so you can track where the traffic is coming from. Each parameter consists of a keyword and a value, separated by an equals sign. You insert the entire string after a question mark in the URL. When someone clicks on the link, the information is automatically sent to your analytics tool. In other words, you’ll be able to track exactly where your efforts have had an impact.
Here's an example of how to build a URL with UTM parameters:
In this example, utm_source indicates the source (Facebook), utm_medium indicates the channel type (social), and utm_campaign indicates the campaign name. You can apply the same principle to social media posts, newsletters, ads, and Google Ads campaigns to obtain comparable data across channels.
That's Why You Should Use UTM
UTM makes the impact of your marketing activities measurable. When you work with multiple channels—such as email, social media, and paid search—it quickly becomes difficult to determine where your traffic is actually coming from. UTM gives you the overview you need by linking data from different platforms together in your analytics tool.
With precise UTM tags, you can, for example, determine whether a specific Google Ads campaign drives more qualified traffic than your organic posts on LinkedIn. This helps you adjust your strategy so you allocate resources where they’ll have the greatest impact. In practice, UTM tags enhance your ongoing reporting, channel analysis, and performance optimization across Amplify’s services, such as SEO, SEM, and social media marketing.
What types and varieties are available?
There are five standard parameters that you can combine, depending on how detailed you want to track your activities:
- utm_source: Indicates where the traffic comes from (e.g., Google, Facebook, or a newsletter).
- utm_medium: Indicates which channel the user clicked from (e.g., email, social, CPC).
- utm_campaign: Identifies the specific campaign (e.g., winter2026 or leadgenQ1).
- utm_term: Primarily used for keywords in paid search campaigns, so you can link click data to search terms.
- utm_content: Distinguish between multiple links within the same campaign, such as two versions of a banner or a CTA link in a newsletter.
When you use these parameters consistently, you can segment and analyze traffic with a high degree of precision. At the same time, you’ll be able to compare campaign performance across channels and time periods without having to guess where the visits come from.
How do you use UTM in practice?
In practice, you create your UTM links using a tool like Google’s Campaign URL Builder or directly through a marketing automation system like HubSpot. Here, you specify the values for source, medium, campaign, and, if applicable, term and content. Once you’ve generated the link, use it in your campaign assets—such as ads, newsletters, social media posts, or QR codes.
An example of how a link appears in a report:
When you analyze the results in Google Analytics, you’ll be able to see exactly how much traffic came from LinkedIn, which pages they visited, and how many actions they took. The same UTM can also be integrated with your CRM system, allowing you to track a visitor all the way from click to conversion. This makes it easier to attribute sales and leads to specific campaign activities and thus calculate ROI more accurately.
What should you keep in mind?
To get the most out of UTM, you need to take a structured approach to naming conventions and formats. Use consistent values so you can compare data without confusion—for example, use “facebook” rather than both “Facebook” and “fb.” This is a matter of data quality, because even small variations can split your statistics across multiple sources.
You should also avoid using UTM parameters on internal links on your own website, because they can overwrite the original traffic source. Instead, reserve UTM tags for campaigns that drive traffic to your website from external sources. Finally, it’s important to check how your links appear when shared, so that long UTM strings don’t ruin the user experience—consider using a URL shortener like Bitly if you share a lot of links on social media.
With a well-thought-out UTM strategy, you don’t just get better data in your analytics tool. You build a solid data foundation that enables you to make informed decisions about SEO, SEM, and other digital activities, because you know exactly what drives results.
