Your Core Web Vitals may be negativly impacted if your AMP page performs really great when served from an AMP Cache, but less well on the origin. A good way to make sure you are delivering a great experience for all your users is to keep track of how your pages' Core Web Vitals are performing on and off of the AMP Cache.</p> <p>We can build on our Google Analytics to do this. One of substitutions provided by amp-analytics is <code>ampdocHost</code> - this lets us track the URL of the page the user visited. We exand our earlier config using <code>extraUrlParams</code>. This lets us define a custom key and value for our analytics events. We need to <a href="https://support.google.com/analytics/answer/2709829">set up</a> a new Custom Dimension, that will be used as the key. </p> <p><amp-img src="/static/img/google-analytics-custom-dimensions-example.jpg" layout="intrinsic" width="1069" height="566" alt="Screenshot of Google Analytics, showing the Custom Dimensions edit page" class="i-amphtml-layout-intrinsic i-amphtml-layout-size-defined" i-amphtml-layout="intrinsic"><i-amphtml-sizer slot="i-amphtml-svc" class="i-amphtml-sizer"><img alt aria-hidden="true" class="i-amphtml-intrinsic-sizer" role="presentation" src="data:image/svg+xml;base64,PHN2ZyBoZWlnaHQ9IjU2NiIgd2lkdGg9IjEwNjkiIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2ZyIgdmVyc2lvbj0iMS4xIi8+"></i-amphtml-sizer></amp-img></p> <p>Once you have created the Custom Dimension to track the AMP Host, make sure you note the <code>Index</code> listed on the analytics page. This number is used in our configuration objects to connect <code>ampdocHost</code> to the Dimension you just created. Below we assume your index was "1", (i.e. <code>cd1</code>). If your <code>Index</code> is 2, then use <code>cd2</code>, etc.</p> <div class="ap-o-code-preview"> <div class="-ta"><pre><span></span><code><span class="p"><</span><span
