If pop-ups are increasing your bounce rate, they may be too disruptive. Keep pop-ups to a minimum and avoid those that appear immediately upon page load. Instead, use timed pop-ups that show after users engage with content, which can reduce bounce rates. Content-obscuring pop-ups are particularly off-putting on mobile, where screen space is limited. A/B test different timings, sizes, and exit-intent pop-ups to ensure they enhance rather than detract from the user experience.
