The Global Translator Plug-in makes your blog reach more people as it automatically translates your blog to other languages. However, be vary of using the Global Translator plug-in especially when using Google Adsense.
The Global Translator Plug-in can translate your blog into 34 languages (if you are using Google Translation service). In terms of getting your pages indexed in Google, that would mean, all your current pages can be seen in 35 languages (English or default language included). That would be a lot of pages and the more pages you have in Google, the better they always say.
However, I would like to warn you about this clause in the Google Adsense Policy. Based on the question, “What languages does Adsense support?” It is stated that,
Please also be aware that placing the AdSense code on pages with content primarily in an unsupported language is not permitted by the Adsense Program Policies
With this new info, I was shocked and was afraid of defying Google once again, so I cross checked the list and filtered out the languages that Adsense supports. Then I disabled the languages that adsense does not support.
Based on that, here is a list of the languages that Adsense supports and what I suggest you leave in your Global Translator Plug-in (disable the other languages).
I’m not really sure what happens but I’m just being paranoid after getting my pagerank back. ^_^
