[@nicholaspistone1847]

Thank you! This was really helpful. I just created a data layer variable to identify user type and create segments for different classes of logged-in users. I'm thinking I will create a Tag+Trigger that fires on window load events and captures the user type and sends it to GA as the event action or something like that. Then I'll create a segment for users with that event to sort each type into its own segment.

Hi all, I would like to know if a value I've already pushed into the datalayer will be cleared when navigating to a new page? I am dealing with a thank you page. Before this, I had already push the info to the datalayer, but it seems that the data disappears when changing pages, so the thank you page doesn't receive the customer's information.

[@JansonSmith]

Thanks for the video. Do you know how to pull the transaction value in GTM if if it's only displayed at the checkout page, and not on the order confirmation? I want the purchase value to go into GTM when a purchase is made, but this info is only provided on the checkout page, not on the order confirmation!

[@funnellmarketing2076]

I really liked this and love your videos. One thing I'm not sure of - I could have any number of products. Is there a more elegant way of pulling this information and pushing it to the dataLayer than simply writing loads of datalayer variables? I mean eventually you'd just give up and say "well, I've written like 30 datalayer variables, and if someone gets 31 products then I guess we just won't be able to grab the 31st item in the array".

[@johnnyrandak960]

Hey Julian I love your videos. I've been learning from you for years now! Hey this is a really basic question-what are the benefits of using data layers and creating events with them? I did some hunting for the high level answer to this question online and was having trouble finding one. Are they mainly used for audience creation? Deduplication? Are data layers more important for eCommerce businesses than other businesses? Thanks for your time!

[@musk.]

Thanks, Julian. One thing I don't understand is creating DLVs for multiple products in a checkout. There's a similar comment below for adding up the price of all products in a cart, but I didn't understand your response to that either. In this example, there are two products but the price of product 1 only corresponds to the first product in the shopping cart, right? My my shopping cart has 3 products and i only have one DLV for product 1 price, are the rest not summed up? Is there a simple solution for getting the total price after a transaction? The data layer and javascript are still very new to me. Thanks again

Thank you Julian for the enlightening tips! i would like to know how the data layer push in variable values is it by a java script right but does the java script pull out this value from the cms? just want to know the technical process and the chain that's going on. it makes it easy to master analytics once you got a granular idea on how's things going from the starting point.

[@MeasureSchool]

you would need to write some server side code that generates the javascript that will push the data to the dataLayer. GTM itself can't access your CMS as it only runs on your Browser.

Your questions is what actually missing from almost so far every tutorial and video. How to build the data object in the first place and what is the process from A to Z. Like virtually how the flow works. I have to make a lot of assumption to conceptualize the workflow and reading Google support docs would bore me to extremes.

[@bettercallsaul6145]

Heyhey, what if you would like to have a conversion in Google ads for every product you have sold? (Lets say we only have 5 products in shop) Can I create a Tag for every product and make it fire by reading out the data layer event based on product name and trigger it based on a rule like - if custom variable matches product name value? But would be difficult because you can’t compare multiple dot notations at the same time 🤨

[@nathanielpatterson5855]

Hi Julian. Great video. Super Helpful! A few curious questions - Is there a way to add up the product price for all products in the cart? Say from 0-100 or something of that nature? If not is there a way to subtract Shipping and Tax from Revenue? Thanks in advance!

yes, there is, with JavaScript. You would need to pull these vaues out of the dataLayer and then write your JS to output the values in another variable (usually a custom JavaScript variable)

Hi Julian. Your videos have been incredibly helpful. Just had a weird case with my shop, the dataLayer variables are getting captured properly inside GTM debug mode but they are not passing it over to the Facebook Pixel.

Just for context, my ViewContent and AddToCart events are capturing custom variables properly which are being used for Dynamic Product Ads.

wondering if anyone can help me with this issue: Have to set up Facebook API and am sending emails as PII, this has already been set up as a DLV.

Given the DLV refreshes for every new page load is there a way I can store the email or push the DLV value into the new page? any experience or links to relevant help would be much appreciated!

Hi, as Julian wont see or answer this - this question is for anyone who tested this - its 2021 - does anyone know of DataLayer push problems with a Wix page? I defined a Dlv variable with the value GTM showed me for that particular key. But when I check the list of variables upon the action on the Wix pg that is supposed to push that key then it simply states its undefined. The key I defined is in the list of variable with the name I gave it but there is no value. What could be the reason? Thanks

I'm tracking the value of the purchases through the dataLayer you showed in the other videos and beside the value and currency for the Facebook Pixel, I was wondering what other information I should include in the pixel and why. For example, I know I can see the amount spent and the value generated directly from Facebook Ad Reports but what can I do with the order number, or pulling any other information from an order.

Hi Julian, great value as usual! I've stumbled upon a little problem and was hoping you could give me some pointers. At first i'd just put 'revenue' for the transaction total which obviously wasn't working (instructions from old vid), luckily I stumbled upon this one. Now when I finish an order in the testarea of GTM the variable finally gets loaded correctly. The FB purchase event also get fired. However when I move into diagnostics of Facebook business manager it says the parameter of value is undefined. Ive tried switching up between '{{dlv-transactiontotal}}' and {{dlv-transactiontotal}}, which gave no different results. Hopefully you can help me out! Thanks

[@MeasureSchool]

probably your facebook pixel is firing, when the variable is not yet filled. You would need to inspect that in the debug view by selecting an event on the left side

We are able to get the dynamic values for language , title and looged in in developer console but if we use the same path in GTM dataLayer variable we are unable to get it . We used path to get values for title like dataLayerLocalAnalytics[0].title , dataLayerLocalAnalytics.0.title nothing works can you please help here. Quick reply is much appreciated.

[@MeasureSchool]

you dataLayer is named dataLayerLocalAnalytics. Obviously GTM doesn't know about your name change and you would need to define this when you initiate the dataLayer.

[@skeepskeeperson]

Maybe an easier way to get the path from the "Chrome" Developer Console would be to find your nested targeted object and right click and then select "Copy property path". With a big note of this will not work in Firefox. The back and forth between GTM and Dev Tools seems way too tedious.

[@MeasureSchool]

good tip, if you prefer that method

[@user-zn5tn9br3b]

I always think, why I can't catch the price data with gtm directly, why the page must have a datalayer ...

because that's the best practice way. If you use scraping (which is possible too), you open yourself up to all kinds of problems, when the website changes

If I had a clear neat list of Enhanced Ecommerce Data Layer Values like the ones you show around 4:10, I wouldn't have to watch all these GTM videos.
