Integrating Google Optimize with Google Tag Manager

1 min · 372 words

You may need to know if the current page has any Google Optimize Experiment running, to track that info on any tool, or to fire some vendor tag based on the current experiments statuses.

The following snippet will take care of sending a dataLayer push if there's any active experiment running, including:

    (function() {
        for (var gtm in window.google_tag_manager) {
            if (gtm.match(/^GTM/)) {
                if (google_tag_manager[gtm].experiment) {
                        'event': 'optimize-experiment-active',
                        'optimize-container-id': gtm,
                        'optimize-exp-name': google_tag_manager[gtm].experiment.split("$")[0],
                        'optimize-exp-variation': 'Variation: ' + google_tag_manager[gtm].experiment.split("$")[1]

    Then just create the needed dataLayer type variables to read the pushed data and use it on your tags/triggers.

    The dataLayer push will look like:

        event: "optimize-experiment-active", 
        optimize-container-id: "GTM-XXXXXX", 
        optimize-exp-name: "GTM-XXXXXX_OPT-YYYYY",
        optimize-exp-variation: "Variation: 1"
