BestsellerMagazine.com - CATEGORY Report update: TITLE
The site map is "top of this hierarchy then down" and you can have as many sitemaps as you like (well, up to 50,000 sitemaps and a max of 2 billion entries)
Place your site maps where they make sense. eg
Each can have a sitemap, or host a sitemap INDEX which links to expressed sitemaps from there.
Theoretically these will assist search engines. Real world empirical evidence indicates this is marginal, at best.
Takeaway is to place your "regional" sitemap at the top of the regional folder to expose all you demand to be known based on that sitemap.
Other side is search engines these days are smart and will index all visible and shared links (that's your back link profile) and then (if you have one) compare those findings to your sitemap, but always relying on their OWN spidering as that is the crux of the matter.
