Good lord, Google Translate is even worse with Japanese than I remember. Sorry! This is a very common phrase in Japanese, that comes up all the time. It means something like "Please work very hard", but it's meant to be very encouraging!

You misspelled your Japanese. In Chinese characters the term is "頑張って," and in kana it is "がんばって." Google Translate did the best it could with what you wrote.

It's still an interesting commentary on Google's handling of Japanese kana. I knew immediately what the GP comment meant to say, but googling (.co.jp) for "ごんばって" doesn't even come up with a "did you mean...?"
