When you have WooCommerce installed it by default loads its scripts and styles on every page of your WordPress site. This is definitely not great for performance. As you can see below on our test site, WooCommerce was loading 8 scripts on our home page, where we don’t even have any products.
Thankfully in the perfmatters plugin, you can now disable WooCommerce scripts and styles everywhere except on product, cart, and checkout pages. Simply select “Disable Scripts” under the WooCommerce section.
We utilize the wp_dequeue_script and wp_dequeue_style functions. You could also use the built-in script manager to achieve the same results. However, the method above is much easier and quicker.
