Google Translate code on each content page??

I am new with Drupal. I have added Google Translate code to each of my website content pages, and it works perfectly. My question; is there a better way to accomplish this instead of adding the code to each page? Someone suggested added it to the “Block” but I’m not sure how that is done. Thanks in advance for your help.
