title: Google Tag Assistant asks feed ID
body: <p>I was asked to upgrade an existing site from using the old remarketing tracking code that looked like this:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  var google_conversion_id = 12345;
  var google_custom_params = window.google_tag_params; // this is empty
  var google_remarketing_only = true;
  &lt;/script&gt;
  &lt;script type="text/javascript" src="https://www.googleadservices.com/pagead/conversion.js"&gt;
  &lt;/script&gt;
  &lt;noscript&gt;
  &lt;div style="display:inline;"&gt;
  &lt;img height="1" width="1" style="border-style:none;" alt="" src="//googleads.g.doubleclick.net/pagead/viewthroughconversion/12345/?value=0&amp;amp;guid=ON&amp;amp;script=0"/&gt;
  &lt;/div&gt;
  &lt;/noscript&gt;
  </code></pre>
  
  <p>to another method that looks like this:</p>
  
  <pre><code>&lt;script async src="https://www.googletagmanager.com/gtag/js?id=AW-12345"&gt;&lt;/script&gt;
  &lt;script&gt;
      window.dataLayer = window.dataLayer || [];
      function gtag(){dataLayer.push(arguments)};
      gtag('js', new Date());
      gtag('config', 'AW-12345');
  &lt;/script&gt;
  </code></pre>
  
  <p>because it is asynchronous and should not block page loading. But the Google Tag Assistant extension that validates that tracking is set up correctly asks me to enter a "feed ID" when using the newer (gtag.js based) method. Previously it was showing Remarketing Tag as green.</p>
  
  <p>Why is it needed now and not with the old code? I asked someone who has access to the AdWords account and they don't have the feed ID (or can't find it...).</p>
  
  <p>I verified that the request to <code>googleads.g.doubleclick.net/pagead/viewthroughconversion/</code> is sent though devtools as described in Verifiction using browser based developer tools:</p>

  <p>Is my configuration correct? </p>
