amp-experiment info not visible in GA or Google Optimize

问题

I've implemented a small experiment on an AMP site following this tutorial: https://developers.google.com/optimize/devguides/amp-experiments

Here's what I've done:

1. amp-analytics and amp-experiment components

<script async custom-element="amp-analytics" src="https://cdn.ampproject.org/v0/amp-analytics-0.1.js"></script>
<script async custom-element="amp-experiment" src="https://cdn.ampproject.org/v0/amp-experiment-0.1.js"></script>

2. Code for the experiment

<amp-experiment>
  <script type="application/json">
    {
      "AMP_Product_Page": {
        "sticky": true,
        "variants": {
          "Original": 50,
          "Variant_1": 50
        }
      }
    }
  </script>
</amp-experiment>

3. Code for analytics

<amp-analytics id='analytics1' type='googleanalytics'>
    <script type='application/json'>
    {
        "vars": {
        "account": "UA-105350-7"
        },
        "requests": {
        "experiment": "${pageview}&xid=${xid}&xvar=${xvar}"
        },
        "triggers": {
            "trackPageview": {
            "on": "visible",
            "request": "experiment",
            "vars": {
                "xid": "fB2hAs9HS2WgWqe332c6Ow",
                "xvar": "VARIANT(AMP_Product_Page)"
            }
        }
        }
    }
    </script>
</amp-analytics>

4. Created an experiment in Google Optimize

I created an experiment in Google Optimize and used the ID in the code above. I can also see the experiment in Google Analytics, it has 0 sessions, though.

I've also added some basic CSS rules and they are working fine.

The code above is live and I can see the experiment running on the site, also the <body> tag has an attribute amp-x-amp_product_page="Variant_1".

Google Analytics requests

I have a Google Analytics integration deployed using GTM AMP container and it's working fine.

Now, when I look at the requests made by Google Analytics, here's what I see:

Pageview request (OK)
Second pageview request with experiment data (status 302)

That second request seems not to make it to GA.

I tried sending experiment data with an event, but it seems like xid and xvar are not allowed variables for an event in amp-analytics.

回答1:

Variants should be numbered instead of named in . So in your case they should be "0" and "1" instead of "Original" and "Variant_1".
