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 the Web SDK extension

Adobe offers an extension that allows you to use most commonly-used plug-ins with the Web SDK.

  5. Click Data Elements on the left, then click the desired data element.

  6. Set the desired data element name with the following configuration:

    • Extension: Common Web SDK Plugins
    • Data Element: getTimeSinceLastVisit

  7. Save and publish the changes to the data element.

Install the plug-in manually implementing the Web SDK

This plug-in is not yet supported for use within a manual implementation of the Web SDK.

Install the plug-in using the Adobe Analytics extension

Adobe offers an extension that allows you to use most commonly-used plug-ins with Adobe Analytics.

  1. Log in to Adobe Experience Platform Data Collection using your AdobeID credentials.

  2. Click the desired tag property.

  3. Go to the Extensions tab, then click on the Catalog button

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".
NOTE
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.

Examples

// 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();
