How do I specify that a page is in a certain language so search engines can understand?
Is it a meta tag I put at the top? If it is, do you know if most of the search engines use this to determine language?
I have converted 1 page of content in english to several different languages, and would like to include that information in the html/let the search engines know which language they are dealing with.

Quick google search gave me this: HTTP and meta for language. tl;dr
<html lang="en">
There are other ways of specifying. If you are using apache, you can use a file extension for apache to pull the correct version based on the user-agent's given preferences. for example, name your index page index.html.en, index.html.jp, index.html.de and so on...

Depending on your dtd:
HTML:
<html lang="en">
XHTML:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
If you are using a right to left language:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="he" lang="he" dir="rtl">
If using XHTML, you'll want to specify both the xml:lang and lang attributes. The xml:lang attribute takes precedence over lang.
