Gives every location its own page on your site, and controls the URLs those pages get.
Create landing pages?
Gives every location its own page, one that search engines can index and customers can link to.
This is the setting most worth turning on. Without it, your locations only exist inside the map, where nothing outside your site can reach them.
Enabling it also changes one behaviour elsewhere: the location name in the results always links to its own page, which overrides the “Make the store name clickable if a store URL exists?” option in User Experience.
How to change the layout of these pages is covered in Create a Custom Store Page Template.
Remove the front base from the permalink structure?
The front base is whatever sits at the start of your Settings > Permalinks custom structure — /blog/, for example. By default your location pages inherit it, giving you /blog/stores/downtown/.
Enable this to strip it, leaving /stores/downtown/.
Store slug
The path segment for location pages. Default stores, giving /stores/downtown/.
Use the word your customers would: branches, dealers, clinics, stockists.
Category slug
The path segment for location category archives. Default store-category.
Only shown when landing pages are enabled.
