2)I'm confused about how that would work with Google:
Let's assume one of my web site's keywords is "weight loss". Obviously, that's built into my web site in English. When someone in, say, Japan enters "weight loss" in Japanese into Google, would Google's results' pages even list my web site ... which is in English?
And if so, is that "summarized entry" (my site's 'Title' or whatever that's called) on Google's SERP, or for that matter, my web site, shown in English or in Japanese?
If shown in English, that does me or Japanese people little or no good, unless they happen to know English. Is there a way around that? Like trying to get the Japanese translated version of my site well ranked? And how the heck do you do that?!
Or having a note in that "summarized entry" (my site's 'Title?) saying that it's available in Japaneses ... but that would have to be written in Japanese, right? And the other languages, too. Confusing.
Can someone help me out?
