webmaster tools and fetch as google bot is probably the easiest indexing method and most effortless. Analytics does not do anything. Links work just as well, but rather than sending crappy links to your site just so you can index it, better take your time and don't rush into things. Especially with how the serps update look, even if you index your website fast, there is no indication that will rank anywhere fast in the first weeks, so no need to risky it.
