The Delivery Suburbs post type works much the same as a Post or Page in WordPress – it is designed to provide a separate place to keep posts for SEO-friendly pages per suburb you deliver to, without cluttering your Posts/Pages menu.
We recommend using something like Elementor Pro (affiliate link) to create a template for the post type that includes a product gallery under the post content. You can then write your unique content per suburb in the post content itself.
We recommend naming the posts with the suburb’s actual name only, and using an SEO plugin to set the page’s SEO/browser title to something like,
Flower Delivery to <suburb> – My Florist | Florist in <shop suburb>
