Adobe plug-in: getTimeSinceLastVisit


This plug-in is provided by Adobe Consulting as a courtesy to help you get more value out of Adobe Analytics. Adobe Customer Care does not provide support with this plug-in, including installation or troubleshooting. If you require help with this plug-in, contact your organization’s Account Manager. They can arrange a meeting with a consultant for assistance.

The getTimeSinceLastVisit plug-in allows you to track how long a visitor has taken to return to your site after their last visit.

Install the plug-in using custom code editor

If you do not want to use the plug-in extension, you can use the custom code editor.

  1. Log in to Adobe Experience Platform Data Collection using your AdobeID credentials.
  2. Click on the desired property.
  3. Go to the Extensions tab, then click the Configure button under the Adobe Analytics extension.
  4. Expand the Configure tracking using custom code accordion, which reveals the Open Editor button.
  5. Open the custom code editor and paste the plug-in code provided below into the edit window.
  6. Save and publish the changes to the Analytics extension.

Install the plug-in using AppMeasurement

Copy and paste the following code anywhere in the AppMeasurement file after the Analytics tracking object is instantiated (using s_gi). Preserving comments and version numbers of the code in your implementation helps Adobe with troubleshooting any potential issues.

Use the plug-in

The getTimeSinceLastVisit function does not use any arguments. It returns the amount of time elapsed since the visitor last came to the site, bucketed in the following format:

  • Time between 30 minutes and an hour since the last visit is set to the nearest half-minute benchmark. For example, "30.5 minutes", "53 minutes"
  • Time between an hour and a day is rounded to the nearest quarter-hour benchmark. For example, "2.25 hours", "7.5 hours"
  • Time greater than a day is rounded to the nearest day benchmark. For example, "1 day", "3 days", "9 days", "372 days"
  • If a visitor has not visited before or the time elapsed is greater than two years, the value is set to "New Visitor".

This plug-in only returns a value on the first hit of a visit.

This plug-in creates a first-party cookie called "s_tslv" set to a Unix timestamp of the current time. The cookie expires after two years of inactivity.


// Given a visitor's first visit to the site
// Sets prop1 to "New Visitor"
s.prop1 = getTimeSinceLastVisit();

// 35 minutes later, the same visitor returns
// Sets prop1 to "35 minutes"
s.prop1 = getTimeSinceLastVisit();

// 4 days later, the same visitor returns
// Sets prop1 to "4 days"
s.prop1 = getTimeSinceLastVisit();
