The tl() method is an important core component to Adobe Analytics. It takes all Analytics variables defined on the page, compiles them into an image request, and sends that data to Adobe data collection servers. It works similarly to the t() method, however this method does not increment page views. It is useful for tracking links and other elements that wouldn’t be considered a full page load.

If trackDownloadLinks or trackExternalLinks are enabled, AppMeasurement automatically calls the tl() method to send download link and exit link tracking data. If your organization prefers to have more control over the links to track and their behavior, you can call the tl() method manually. Custom links can only be manually tracked.

Launch has a dedicated location set a link tracking call.

  1. Log in to using your AdobeID credentials.
  2. Click the desired property.
  3. Go to the Rules tab, then click the desired rule (or create a rule).
  4. Under Actions, click the ‘+’ icon
  5. Set the Extension dropdown to Adobe Analytics, and the Action Type to Send Beacon.
  6. Click the radio button.

You cannot set any optional arguments in Launch. method in AppMeasurement and Launch custom code editor

Call the method when you want to send a tracking call to Adobe.[Link object],[Link type],[Link name],[Override variable]);

The link object argument determines if the browser waits up to 500ms before navigating away from the page. If an image request is sent sooner than 500ms, the page immediately navigates to the clicked link.


AppMeasurement automatically enables the useBeacon variable for exit links, making this argument no longer needed in modern browsers. This argument was used more commonly in previous versions of AppMeasurement.

  • this: Wait up to 500ms to give AppMeasurement time to send an image request. Default value.
  • true: Do not wait.
// Include a 500ms delay with an exit link,"e","Example exit link");

// Do not include a 500ms delay with an exit link,"e","Example exit link");

The link type argument is a single-character string that determines the type of link tracking call. There are three valid values.

// Send a custom link,"o","Example custom link");

// Send a download link,"d","Example download link");

// Send an exit link,"e","Example exit link");

The link name argument is a string that determines the link tracking dimension item. When using the Custom link, Download link, or Exit link dimensions in reporting, this string contains the dimension item. If this argument is not set, the linkURL variable is used.

// When using the Download link dimension, this method call increases the occurrences metric for "Sea turtle PDF report" by 1.,"d","Sea turtle PDF report");

Variable overrides (optional)

Lets you change variable values for a single call. See variable overrides for more information.

var y = new Object();
y.eVar1 = "Override value";
y.linkTrackVars = "eVar1";,"o","Example custom link",y);

Examples and use cases

Send a basic link tracking call directly inside an HTML link:

<a href="example.html" onClick=",'o','Example link');">Click here</a>

Use JavaScript to make a basic link tracking call using method arguments:,"o","Example link");

You can consolidate link tracking code into a self-contained JavaScript function defined on the page or in a linked JavaScript file. Calls can then be made in the onClick function of each link. Set the following in a JavaScript file:

function trackClickInteraction(name){
  s.linkTrackVars = "eVar1,eVar2";
  s.eVar1 = name;
  s.eVar2 = s.pageName;,"o",name);

You can then call the function whenever you want to track a given link:

<!-- Use wherever you want to track links -->
<a href="example.html" onClick="trackClickInteraction('Example link');">Click here</a>

If trackDownloadLinks or trackExternalLinks are enabled, AppMeasurement automatically makes a link tracking call if the correct filters match. If you also manually call for these link clicks, you can send duplicate data to Adobe. Duplicate data inflates report numbers and makes them less accurate.

For example, the following function would send two link tracking calls for same link click (manual and automatic download links):

function trackDownload(obj) {,"d","Example PDF download");

You can help prevent duplicate link tracking calls by using the following modified function. It first checks to see if a link object exists, and only sends a manual link tracking call if the link object is an empty string.

function linkCode(obj) {
  var lt = obj.href != null ? : "";
  if (lt=="") {,"d","Example PDF download");
