Tracking conversion start time, end time, and duration - HandL UTM Grabber Guide

UTM attribution overview

This guide explains Tracking conversion start time, end time, and duration - HandL UTM Grabber Guide. It helps you capture UTM source, medium, campaign, term, content, click IDs, referrer, and landing page data and keep the marketing context needed for accurate reporting across forms, bookings, signups, and sales.

Please request the custom version via chat, and we'll provide it to you.

After you activate the custom version, you will have three additional cookies (parameters) added:

  1. Tracking conversion start time, end time, and duration:
    • handl_journey_start: This is an epochUnix timestamp in milliseconds

    handl_journey_duration_hrsThe time from the journeystart to the end, in whole hours (rounded)54

    Journey Duration is built into UTM Grabber from version 3.3.9 and is off by default.

    Turn on Journey Duration

    1. Go to WordPress Admin > UTM and open the HandL Options tab.
    2. Tick Track Journey Duration.
    3. Click Save Changes.

    Track Journey Duration setting in HandL Options

    From then on, UTM Grabber records the start time on each visitor's first visit, and updates the end time and duration on every page they view.

    How the values are set

    • The start is set once. handl_journey_start is saved on the visitor's first page view and isn't reset when they convert. If someone fills in a form in week 1 and places an order in week 3, the order's duration still counts from their first visit. The start is kept for as long as UTM Grabber's cookies last; see Setting the firstCookie time.Duration.
    • handl_journey_duration_hrs:The end and duration follow the visitor. Thishandl_journey_end and handl_journey_duration_hrs are updated on every page view, so a form or order saves the values from the moment it was submitted.
    • Consent applies. If you use UTM Grabber's GDPR option or a consent integration, the values are only saved once the visitor gives consent, like your other tracked fields.

    Save the values with your forms and orders

    The three fields work like any other UTM Grabber field:

    • WooCommerce orders save them automatically.
    • One Click Integrations list them with your other tracked fields. If you connected forms before turning on Journey Duration, open the Integrations tab: those forms show the three fields as missing, and you can add them from there. See One Click Integrations.
    • Hidden fields named handl_journey_start, handl_journey_end and handl_journey_duration_hrs are filled in, the same way as your UTM fields.
    • Shortcodes [handl_journey_start], [handl_journey_end] and [handl_journey_duration_hrs] show the values anywhere shortcodes work. See Native WP Shortcodes.

    To show a timestamp as a date in Google Sheets or Excel, use =A2/86400000+DATE(1970,1,1) and format the cell as a date and time. The result is in UTC.

    Using the durationcustom build?

    Journey Duration used to need a custom version of the conversionplugin. If your site ran that custom build, update to the latest UTM Grabber and tick Track Journey Duration in hoursHandL (rounded)Options. Until you do, the three fields stop being saved and the shortcodes show as plain text.
