My site's homepage has textual content related to the site's keywords. To rank well in mobile/desktop SERPS, do you need to include that textual content on a site's mobile theme? I created a mobile theme for an ecommerce site of mine, but it doesn't show the homepage's keyword related article, only the categories. And I'm wondering if I need to include a large wall of article text on the mobile site for SEO purposes, just like it's necessary for desktop SEO. Anyone know?
