Can a product page in WooCommerce be Used as a Focus Page?

Yes, you can add WooCommerce products in Focus Pages.

We’ve been using this ourselves on a few online stores ourselves and it’s a great money maker, especially because many store owners never go to optimize the content on their product pages.

It will give you a great advantage!

If your theme allows for custom text inside WooCommerce category pages, that can also be a gold mine for Focus Pages-driven results.
