title: Listing both sitemaps and sitemap index files in robots.txt?
body: <p>My site is comprised of 3 main sections: Reviews, Forum, and Blog. I have plugins for the forum and blog that automatically generate sitemaps for them. The forum plugin generates a sitemap INDEX file pointing to multiple indexes, and the blog plugin generates a regular sitemap file containing all my blog content. Here are their entries from robots.txt:</p>
  
  <pre><code>Sitemap: http://www.datesphere.com/forum/sitemap-index.xml
  Sitemap: http://www.datesphere.com/blog/sitemap.xml
  </code></pre>
  
  <p>I just created a Reviews sitemap.xml file that contains all the content in the Reviews section. I was planning to just add a line to robots.txt so the whole thing would look like this:</p>
  
  <pre><code>Sitemap: http://www.datesphere.com/forum/sitemap-index.xml
  Sitemap: http://www.datesphere.com/blog/sitemap.xml
  Sitemap: http://www.datesphere.com/reviews-sitemap.xml
  </code></pre>
  
  <p>HERE'S MY QUESTION: I know you can list multiple sitemaps in robots.txt, but is it OK to have a sitemap index file as well as multiple sitemaps listed? Will Googlebot ignore the other sitemap files if it finds a sitemap-index.xml file in robots.txt? If so, do I have to put my blog and reviews sitemaps in another sitemap index file and just list that in robots.txt?</p>
  
  <p>I've checked around but can only find answers to the question "can I list multiple sitemaps?"</p>
