Online Catalog is simple, there is only one version of your website and the websites’ design will “respond” to whatever device you are viewing it on. In most cases, large images that are not necessary on a small screen will compact or disappear, content, articles and other elements on the page will neatly stack themselves on top of one another to accommodate the screen you are viewing it on.

Mobile optimization is the process of ensuring that visitors accessing your website from mobile devices have an engaging and user-friendly experience that's been optimized for that specific device.
