title: do i need sitemaps for each subdomain for site?
body: <p>I have a site built using different smaller sites hosted on subdomains. There are a lot of links between the subdomains and root domain, so all pages can be reasonably reached. </p>
  
  <p>Do I need a separate sitemap for each of the sites? One of the smaller sites is a WordPress blog, for which generating a sitemap is easy. However, some of the others don't have a sitemap generator. </p>
  
  <p>Do I really need a sitemap for each of the sites or can I expect google to crawl all the pages as long as there is at least one link to them?</p>
