I'm putting together meta data for an English website whose target search demographic is the Hispanic market. The website has a Spanish translation as well. When I entered the website into the Google Adwords keyword tool to begin doing keyword research, all keywords returned to me were in Spanish. I am unsure if the meta data keywords I'm preparing for the page should be in Spanish despite the fact that I am preparing the meta data for the English version. Moreover, should there be any mixed Spanish English (Spanglish?) keywords as users might be searching under the English search but in Spanish or with queries that are partially in Spanish?

Are misspelled brand queries considered branded keywords? I'm trying to segment branded traffic and wasn't sure what to include.
