I have an e-commerce site built on Nuxt.js and tracking set up in Google Tag Manager with Analytics. Whenever someone checks out, on the confirmation page I push to the dataLayer the checkout event (code below).
My problem is that sometimes the transaction is duplicated, sometimes the next day. The confirmation page cannot be reloaded or revisited and I get about 2 or 3 duplicates a week. I have seen creating custom tasks in analytics to prevent duplicate transactions but thought there has to be a simpler answer.
dataLayer.push({
'event': 'checkout',
'ecommerce': {
'checkout': {
'id': product.id,
'name': product.name,
'category': product.category,
'price': product.price.replace(/,/g, ""),
'quantity': 1
}
},
});
It seems that for some users the it was caching the ecommerce object and pushing on other events. To avoid this I just put the following code after pushing my purchase event:
dataLayer.push({ ecommerce: null });

I have a production site in which my transactions are all recorded in google analytics correctly. Recently we have decided to create a staging environment which will be a replica of production. For this staging environment I created a new google account and hooked it up with Anaytics and Google tag manager. I then updated the code in staging environment to use this UA and GTM account ids.
When I look at my staging GA dashboard now, I see data, however I do not see a 'transactions' heading under 'ecommerce' and there is nowhere I can see my transactions. I have enabled 'ecommerce' for this GA dashboard from Account > Settings. Is there anything else I need to configure to see transactions in the dashboard?
Here is the official GTM dataLayer GA Enhanced Ecommerce spec:
https://developers.google.com/tag-manager/enhanced-ecommerce
Transactions are referred to as "purchase":
https://developers.google.com/tag-manager/enhanced-ecommerce#purchases
<script>
dataLayer.push({
'ecommerce': {
'purchase': {
'actionField': {
'id': 'T12345', // Transaction ID. Required for purchases and refunds.
'affiliation': 'Online Store',
'revenue': '35.43', // Total transaction value (incl. tax and shipping)
'tax':'4.90',
'shipping': '5.99',
'coupon': 'SUMMER_SALE'
},
'products': [{ // List of productFieldObjects.
'name': 'Triblend Android T-Shirt', // Name or ID is required.
'id': '12345',
'price': '15.25',
'brand': 'Google',
'category': 'Apparel',
'variant': 'Gray',
'quantity': 1,
'coupon': '' // Optional fields may be omitted or set to empty string.
},
...
The spec documentation isn't of the highest quality, so for a happy implementation I recommend the following best practices
dataLayer.push not working after GTM script
Always initialize the dataLayer
Always set the "event" property
To facilitate your life even more, you can do:
Event = ecommerce_{action}
Category = Ecommerce
Action = {action} (eg purchase, click...)
The event naming convention will allow you to create 1 single GTM trigger (Event REGEX ecommerce_.*) and therefore 1 single tag to capture all your Ecommerce events (having to create separate triggers/tags for each Ecommerce action is unnecessary and painful)
Once that's done, create a GTM Google Analytics Event tag with the above trigger, and enable Ecommerce in the GA settings:
I need your help about GTM and UA.
Like this exemple i catch the Event in Google Analytics that's work fine :
// Measure the removal of a product from a shopping cart.
dataLayer.push({
'event': 'removeFromCart',
'ecommerce': {
'remove': { // 'remove' actionFieldObject measures.
'products': [{ // removing a product to a shopping cart.
'name': 'Triblend Android T-Shirt',
'id': '12345',
'price': '15.25',
'brand': 'Google',
'category': 'Apparel',
'variant': 'Gray',
'quantity': 1
}]
}
}
});
In Analytics i can catch the "Event" but where is products data ?
Thanks in advance for your help.
The products data is in the datalayer. You can set set the GA tag to read the dataLayer (alternatively you can set it to use an E-commerce-Variable containing the product data). This is just not very visible in the documentation, you need to click the little green arrow below the code example to expand the description of how to configure your tag (the example assumes you are using and event to send e-commerce data):
If you use a GA setting variable you might need to click "override settings" in the GA tag first.
I am currently trying to send custom dimension values with the product impressions event. Everything else seems to work but I am not able to report on the custom dimension values.
I have set up dimension8 and dimension 9 for star rating and review count. I have passed through these values to the object and it is successfully being sent.
dataLayer.push({
'event': 'productDetailImpressions',
'ecommerce': {
'detail': {
'actionField': {
'list': 'PDP'
},
'products': [{
'name': name,
'id': id,
'price': price,
'brand': brand,
'category': category,
'variant': variant,
'dimension8': reviewCount,
'dimension9': starRating
}]
}
}
});
I have set these custom dimensions up with product scope in GA.
I can view the tag and the information it is sending with a plugin in the browser, the values look correct.
However I am still not able to report on these values inside Google Analytics.
Is there anything I am doing wrong?
Thank you.
The scoping of dimensions required 2 things:
Configure scope in Google Analytics admin interface
See below screenshot:
Send custom dimension with the proper hit
Data is sent to Google Analytics with "hits". Hits are:
page tracking hits
event tracking hits
ecommerce tracking hits social
interaction hits
Now this doesn't mean that you should structure your dataLayer so that the custom dimensions are on the same level ase the object (eg user, product) you're trying to associate them with. Instead, you should follow the standard method for setting dimensions:
In Google Analytics, it is:
// Set the dimension
ga('set', 'cd1', 'Level 1');
// Send custom dimension along with a hit (eg pageview)
ga('send', 'pageview');
Now with Google Tag Manager, GTM doesn't send any hits to Google Analytics, it's just a tool for preparing your data and automating the use of GA. So an example on how to do it:
dataLayer.push({
'event': 'productDetailImpressions',
'dimension8': reviewCount,
'dimension9': starRating,
'ecommerce': {
'detail': {
'actionField': {
'list': 'PDP'
},
'products': [{
'name': name,
'id': id,
'price': price,
'brand': brand,
'category': category,
'variant': variant,
}]
}
}
});
Then create some dataLayer variables to read the custom dimension values:
Finally, assign those dimensions to your GA tags:
note: you could potentially make it work with the dataLayer you have, you would just have to replace your dataLayer variable to point to the right location, however I think it's bad practice because it leads to believe that dimensions have to be nested within the scoped object in order to work (which is not true) and it makes things harder to debug.
I have problems organizing a proper GTM debugging for a new project. I was trying to setup a basic tag from their docs, using:
<script>
// Measure a view of product details. This example assumes the detail view occurs on pageload,
// and also tracks a standard pageview of the details page.
dataLayer.push({
'event': 'gtm.load',
'ecommerce': {
'detail': {
'actionField': {'list': 'Apparel Gallery'}, // 'detail' actions have an optional list property.
'products': [{
'name': 'Triblend Android T-Shirt', // Name or ID is required.
'id': '12345',
'price': '15.25',
'brand': 'Google',
'category': 'Apparel',
'variant': 'Gray'
}]
}
}
});
console.log("Pushed");
</script>
as tracking code, and also setting up the basic GTM tag, as suggested by the example: https://developers.google.com/tag-manager/enhanced-ecommerce#details
And using the Window Loaded event type for trigger.
The gtm debugger shows that events are triggered.. But nothing appears in google analytics.
I was also checking, if some messages are being sent to GA using the firebug, and looks like they are sent:
Sent beacon:
v=1&_v=j47d&a=681300097&t=pageview&_s=1&dl=http%3A%2F%2F192.168.0.107%2F%3Fproduct%3Dtest-product&ul=en-us&de=UTF-8&dt=test%20product&sd=24-bit&sr=1366x768&vp=1351x415&je=0&fl=22.0%20r0&_u=SCCAAAALI~&jid=&cid=247695807.1477915334&tid=UA-73812011-1>m=GTM-TWQ9DJ&pal=Apparel%20Gallery&pa=detail&pr1nm=Triblend%20Android%20T-Shirt&pr1id=12345&pr1pr=15.25&pr1br=Google&pr1ca=Apparel&pr1va=Gray&z=280618779
There are a couple of options here, depending on how much control you have with the page code. If you have full control, and if you want you load the ecom data on page load, then you do a dataLayer declaration with that data just before your GTM container:
dataLayer = [{
'ecommerce': {
'detail': {
'actionField': {'list': 'Apparel Gallery'}, // 'detail' actions have an optional list property.
'products': [{
'name': 'Triblend Android T-Shirt', // Name or ID is required.
'id': '12345',
'price': '15.25',
'brand': 'Google',
'category': 'Apparel',
'variant': 'Gray'
}]
}
}
}];
Doing it this way allows you to capture the data on page load with your pageview tag.
You shouldn't do it with an event push, not especially with an event named gtm.load as that is the built-in event that gets pushed when the page assets have completely loaded, so you are probably not seeing data as there is a conflict with your 'page load' since there are now two gtm.load events being pushed.
If you still prefer an event, then just use a different name, eg. myEvent, and then create an event tag to fire on that event.
Lastly don't forget to enable your tag to use the dataLayer in order to capture the ecom info.
I want to use GTM to track eCommerce transactions. This is a test for client environments where the code might be placed after the GTM code snippet which is why using Dom Ready as a trigger for the transaction tag is not reliable.
This is my test code:
<body>
<!-- Google Tag Manager -->
<script>window.dataLayer = window.dataLayer || [];</script>
<noscript><iframe src="//www.googletagmanager.com/ns.html?id=GTM-M4RNT2"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'//www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-XXXXXX');</script>
<!-- End Google Tag Manager -->
<div class="container">
<script>
window.dataLayer = window.dataLayer || []
dataLayer.push({
'transactionId': '32698',
'transactionAffiliation': 'Acme Clothing',
'transactionTotal': 38.26,
'transactionTax': 1.29,
'transactionShipping': 5,
'transactionProducts': [{
'sku': 'DD44',
'name': 'T-Shirt',
'category': 'Apparel',
'price': 11.99,
'quantity': 1
},{
'sku': 'AA1243544',
'name': 'Socks',
'category': 'Apparel',
'price': 9.99,
'quantity': 2
}]
});
</script>
</body>
As you can see the eCommerce code is taken straight from the Google documentation here.
I made sure that the pageview tag I'm firing works and I can see myself on the realtime view.
The issue is that no matter what I do to trigger the transaction tag, no eCommerce transactions are shown in Google Analytics.
Here is what I've tried:
Using 'event': 'eCommerce' right after the transaction products or in a separate script tag after the transaction code push and then using that event as a trigger
I've created a dataLayer variable in GTM that references transactionId and defaults it to false and then using event gtm.dom as a trigger with a filter for transactionId does not equal false
The frustrating part is that I have the GTM preview window open and it looks perfectly like it should work.
In attempt 1 above it shows a sequence of pageview, message, eCommerce DOM ready, page load where the dataLayer after message is correctly filled with transaction data and the eCommerce tag firing on the eCommerce event (i.e. data is in the dataLayer for sure.
In attempt 2 the dataLayer after Message is filled with transaction data and the eCommerce tag is fired on the DOM Ready event.
This has been going on for days now so it isn't a case of "the data hasn't shown up in GA yet". I am using the right UA tag since both tags reference the sasme onstant GTM variable and since I see myself in realtime the pageview tag uses the right UA and therefore so does the transaction tag. And yes eCommerce is obviously enabled in the view settings.
Simply pushing the transaction data to the data layer will not trigger the tracking to work. You need an action such as a pageview to pick up the transaction data and send it.
If you are unable to add the data layer before the GTM snippet, my recommendation would be the following:
Convert your code to be in the Enhanced Ecommerce format (provided below)
Add a custom event, in this case it is named trackTrans.
Add an event tag in GTM, labeled similar to Send Transaction. You can specify whatever values you'd like the for the event category/action/label.
In the event tag go to more settings > Ecommerce Features, enable Enable Enhanced Ecommerce Feature and Use data layer
Setting the trigger to be a Custom Event and specify trackTrans for the value
In your view settings make sure to enbable enhanced ecommerce tracking
dataLayer.push({
'ecommerce': {
'purchase': {
'actionField': {
'id': 'T12345', // Transaction ID. Required for purchases and refunds.
'affiliation': 'Online Store',
'revenue': '35.43', // Total transaction value (incl. tax and shipping)
'tax':'4.90',
'shipping': '5.99',
'coupon': 'SUMMER_SALE'
},
'products': [{ // List of productFieldObjects.
'name': 'Triblend Android T-Shirt', // Name or ID is required.
'id': '12345',
'price': '15.25',
'brand': 'Google',
'category': 'Apparel',
'variant': 'Gray',
'quantity': 1,
'coupon': ''
}]
}
},
'event' : 'trackTrans'
});
With what I have described above, the page will load then an event will fire and send the ecommerce transaction data with it.
As per your reference to the Google documentation, you need to
Place this code above the Google Tag Manager container snippet so that the data layer is ready when Google Tag Manager fires the Google Analytics tag asynchronously.
I have found a way to make it work. Ryan's answer was close but our experience with using event based triggers was spotty at best. I am now using the following setup that essentially guarantees transaction pickups by GTM unless the code is dynamically injected after page load via JS.
Here is how:
I created a dataLayer Variable which references transactionId and set its default to false
I created a trigger of type Custom Event, set the event to gtm.dom and a filter for the dataLayer variable I created to be not equal to false.
This ensures an actual transaction on the page overwrites the default value of false in that GTM variable and the gtm.dom trigger ensures that all code has loaded.
We have already tested this with clients on varying degrees of awfullness in terms of GTM implementations.
