If you run a WooCommerce store, you don’t want visitors landing on your shop page only to be greeted with a blank white screen. This happens when users aren’t able to see any content on your website due to render-blocking issues. They’ll see content when it finishes downloading.
This not only causes visitors to bounce off your website immediately but also makes your website appear to be broken. Most site visitors will only stick around for about 2 seconds waiting for content to show up on their screens. After that, they’ll bounce off and, most likely, never come back.
