My index page contains no textual content at all (except some footer links, copyright notice and some stuff in tag). It has, however, big Google's map with some pins attached which lead to articles. Of course this is the page I want to pop up in search results when user types my site name into Google.
In this case, should I add my index page to sitemap.xml? Thanks for any help. (Sorry, I can't paste link to this site yet.)
