i've been seeing so many researchers reporting "false" drops in engagement because their heatmaps are firing before the actual content even loads. if you're testing a high-res hero change, i always use a window load listener to trigger the conversion pixel instead of just the page view. it prevents that
skewed data where users bounce because the image is still buffering and your tool thinks they actually interacted with the page.
window.addEventListener('load', function() {window.dataLayer.push({'event': 'hero_image_ready'});});have you guys tried switching your triggers to window load for heavy media tests?
