Just starting using adsense, how do I know that I am set up to serve ads to the correct location/language. Can't see anything to check this when logged in?

You can't. Its the Adwords advertiser that specifies the language and geolocation that their ads get served.

Hi,

I wouldn't say that you can't ...

... we have a site http://www.w62.net where we're selling construction machinery. The site supports 10 languages and what we simply did was to set up a main index page where we added a meta tag to the header section:
<META NAME="language" CONTENT="en,de,fr,it,es,pt,nl,ru,gr,jp">

now google displays kind of mixed ads from different countries and in different languages on our main page ... from the main index page you may enter a certain country's index page where the language tag is only set to the specific country's 2dig code, like:
<META NAME="language" CONTENT="en">
or <META NAME="language" CONTENT="de">
or <META NAME="language" CONTENT="fr">
...



Unfortunately it does not always work out but most of the times it really does! Somewhere on the google site you'll find a list of supported countries/languages. I've lost the link to that list but it shouldn't be too difficult to find.
