SITEMAP BASICS
Does a small website need a sitemap?
A small site with clear internal links may already be easy for crawlers to explore. A sitemap can still be a useful inventory and a simple way to expose your preferred public URLs.
Do not treat the file as a substitute for navigation. Make sure visitors and crawlers can reach important pages through ordinary links. If your website platform already maintains a correct sitemap, there may be no need to generate another manually.
