title: Can I use Google Tag Manager to collect analytics from mulitple domains?
body: <p>The set-up:</p>
  
  <ul>
  <li>1 site, 2 domains:  = mysite.com and mysite.co.uk</li>
  <li>These 2 domains use DNS to point to the same site (IP).</li>
  <li>There is 1 snippet of Google Tag Manager (GTM) code just after the opening <code>&lt;body&gt;</code> tag of the site (every page). </li>
  <li>In the GTM container, I have added both domains on the "Container Settings" page.</li>
  <li>There is one Google Analytics (GA) account which only contains the .co.uk domain. (An analytics account can only contain 1 domain.)</li>
  <li>A tag has been set up in GTM with the type of Google Analytics and it has the UA code from the 1 GA account added.</li>
  <li>A rule has been added to fire on all pages</li>
  </ul>
  
  <p>Now, I don't care whether someone visits via .com or .co.uk, but I want to capture combined analytics for both. My questions is, with the way I've set things up using GTM, will GA save data for both domains ie mysite.com and mysite.co.uk, or do I need to set things up another way to achieve this? Ideally, I don't want to go down the forwarding route i.e. forward all traffic from .com to .co.uk.</p>
