Removing the footer from the checkout page is important if you want to reduce exit points and increase conversions. Remember, the more distractions and exit points the checkout has, the more likely the user will navigate away from paying. Unlike a lot of alternative snippets, this code will only remove the footer from page where the user pays for their order meaning it is shown once again on the Thank You page (order-received endpoint).
