What is a URL tracker?

A URL tracker, also known as a tracking URL, is a link with parameters appended to a standard URL that captures and sends data to analytics or attribution systems, enabling measurement of user interactions and campaign performance.

When a user clicks (or views, in the case of impression tracking) a URL tracker, the information embedded in the link is collected by a measurement system as the user is routed to their destination.

In most cases, the process follows three key steps:

1. Tracking parameters are added to a standard URL to encode information about the campaign, traffic source, and other contextual data.
2. The request is sent to a tracking endpoint, where the parameters are logged alongside details such as timestamp, device, and source.
3. The user is routed to the intended destination, such as a website, landing page, or app store.

A URL tracker consists of several components that define how tracking data is structured and interpreted:

• Base URL (destination): This is the final destination where users are directed, such as a website, landing page, app store, or in-app content.
• Tracking domain or endpoint: The address that receives and processes tracking data when a user interacts with a link. It acts as the collection point where the interaction is recorded as the user is redirected.
• Query string and tracking parameters: The portion of the URL that appears after a question mark (?). It contains tracking parameters, which are key-value pairs that define campaign attributes.
• Event type (click or impression): The type of interaction being tracked, which determines how the interaction is handled within measurement systems.

Example of a URL tracker

The example below shows a standard URL tracker format commonly used in web analytics. In the image, utm_source=facebook identifies the traffic source, while utm_medium=paid_social defines the channel. The utm_campaign=spring_sale parameter specifies the campaign name, and parameters, such as utm_term=discount and utm_content=banner_ad, provide more granular details, such as keywords, targeting, or creative variations.

URL trackers provide visibility into which marketing activities drive traffic and conversions by gathering detailed information about user interactions, such as the source, campaign, or creative that prompted a visit. Each click or impression is attributed with greater accuracy, so activities aren't mistakenly classified as direct or organic. 

With a clear picture of marketing performance, it's easier to compare channels, identify high-performing creatives, and analyze which audience segments deliver strong results. Insights from this level of depth support smarter budget allocation, ongoing campaign optimization, and quick adjustments as new data comes in.

Within Adjust, URL trackers, also referred to as links, are used to define campaign structures. Each link corresponds to a specific combination of network, campaign, ad group, and creative, forming a standardized campaign hierarchy. This hierarchy provides a consistent framework for organizing campaign data across networks and channels.

Additionally, Adjust links can be configured with redirect parameters to control how users are routed after interacting with a campaign. For example, you can direct users to an app store, a specific in-app destination, or a fallback page, depending on campaign setup.
