Google has had a pretty nice feature for webmasters called, Google Sitemaps, which allows you to submit a list of links (a.k.a. a sitemap 
) directly to Google so they know what pages exactly to crawl and index.
They have now updated sitemaps to include the ability to submit a mobile sitemap. URLs indexed from this sitemap will be accessible to users searching via Google’s Mobile Search.
