A DigitalPoint Forums advertiser was wondering how to display relevant ads to his non-English sites. Because he's embedding a lot of YouTube videos with English descriptions, AdSense seems to be feeding him with ads that are English even though they are not pertinent to his reader base.
I did some research and discovered this Google AdSense Help Page that shows you how change your display language. The steps required are as follows:
- Log in to your account at https://www.google.com/adsense
- Click the My Account tab
- Click the Login Information  link
- Select a language from the Display Language drop-down list
- Click Save Settings
