50$ free Google Adword credit

I got this 50$ free Adword credit when I signed up with Google Adwords for first time through this link.

This 50$ is valid and offered to only new A/C. To sign up you should have a valid credit card and have to deposite 5$ initially.
If you have already signed up with Google Adwords create a new A/C to get this 50$.

Use this 50$ carefully to maximise your benefit.
