In the past, we implemented a CDN to reduce bandwidth costs by 80%, and our page speed increased as the CDN cached images closer to the user. As an additional improvement, I proposed transforming the images to make them smaller and using a next-gen format to reduce the size even further. At that point, the business didn’t see the value in this, but a few months later, guess what? I was requested to check how we could improve the listing page speed.
