Last week Google announced the availability of new AdSense user forums in French, bringing the total to 6 supported languages.  Continuing their internationalization efforts, Google announced yesterday that AdSense for content is now available in 4 additional languages.  If your website is in Croatian, Czech, Slovak, or Traditional Chinese, you can now put AdSense for content on your site and the ads will appear in the proper language.

Until the Google crawler visits your site and determines the language, ads may not appear in your native tongue.  Crawling can take up to 48 hours but, once complete, ads in the primary language or your site should begin to appear.

AdSense for content is currently available in 22 languages.
