I’m still very new to running an online store and honestly didn’t even know website speed was such a big deal. My shop used to feel a bit slow, and I thought it was just normal. After installing CrazyLoad, everything started loading faster right away, and I didn’t have to do anything complicated myself. For someone like me who doesn’t understand all the technical stuff, it was super easy and made my store feel much smoother for customers.
