title: How to manually change the Google Analytics tracking code on your website
body: <p>A few months ago the Google Analytics tracking code on a website suddenly changed. It was different before and since it has changed, Google is not collecting any data anymore. The solution for this is to change the code on every page of the website to the new one, but to do it manually this will take me hours. Is there an easier way?</p>
  <p>I already tried to link the new code to the old one in Google Analytics, but that doesn't give any result.</p>
  <p>So... What I'm wondering is:
  Is there a possibility to add your own tracking code in Google Analytics?
  Or would it be possible to change the GA tracking code on the website <strong>once</strong> instead of doing it for every page?</p>
