I have an ad written in Swedish. Three of them in fact, two images and a text ad. Which is the better option?
1.) Choose "Swedish" in the language settings and "Sweden" in the countries settings.
2.) Choose "all languages" in the language settings and "Sweden" in the countries settings.
3.) Choose "Swedish" and "English" in the language settings and "Sweden" in the countries settings.
I have this doubt because I'm not sure what Google uses to deduce what language a user speaks: their browser language setting or the version of Google they are using (e.g. google.se) If that's the case, there must be many swedes using google.com, hence my idea of number 3 option.
The other thing is I am running a content-only campaign so these ads won't even be on google sites, only on sites showing AdSense, so if google generally looks at the google site being used to determine language, how would that work on a content-only campaign?
