title: Does Google Analytics tracking code tie to a specific domain?
body: <p>A simple question.</p>
  
  <p>When I set up Google Analytics and use the assigned tracking code, does GA automatically filter results coming from the Domain URL I specify for that tracking code?</p>
  
  <p>In other words, if I used UA-1234567-8 on mysite.com and mysite2.com, will both sites get tracked or will just the site that's entered as my "Domain URL" in my account profile get tracked?  I can't seem to get definitive verification.</p>
