If your site is new..... Socially Bookmark Set-up and XML sitemap Submit sitemap to Google Webmaster Tools If your site has already been crawled...then you may just have to wait...Google crawls websites every 2 weeks or every month or so. If you want to change the crawl stats you must add something new to your website everyday....this will entice the crawlers to return more often.
Put a link to your site on pages that get crawled often such as Digg or this forum. When google crawls and sees your link it will get indexed quickly.
