Step 1: Login in Google Tag Manager and go to the container you want to use.
Step 2: Click Add a new tag.
Step 3: Give it a name (e.g: SparkLoop Tracking Script) and select Custom HTML
Step 4: In the textarea, paste the SparkLoop Tracking Code.
Step 5: Now we need to tell Google Tag Manager when to trigger the script. Scroll down to the Triggering section, click on it and choose when to trigger the tag. We highly recommend selecting All pages to load the SparkLoop Tracking Script on all your pages but feel free to set up a different targeting rule.
Step 6: Save your tag.
Step 7: Click the Submit button on the upper right-hand side of the page to publish your changes. SparkLoop Tracking Script has now been installed!
