Storefront Call To Action Bar
A Storefront extension to place a call to action bar within Storefront at various possible places (above the footer widgets, perhaps, or in the header area?). This could link either to a specific URL or to a WooCommerce product, if available.
These links would be tracked and reported on within the WordPress admin.
A rudimentary version of this is available for free here: https://wordpress.org/plugins/storefront-footer-bar/
