For displaying best selling products with WooCommere the
[products best_selling="true"] or
[best_selling_products] shortcodes can be used. If your WooCommerce version is lower than 3.2 then you can only use the latter since the
[products] shortcode did not support the
best_selling attribute in the earlier versions.
The appearance of the displayed products depends on your active theme, the following examples are using Chap theme, but the shortcodes work with any theme as long as you’re using WooCommerce.
[best_selling_products columns="5" per_page="5" /]
