This application has changed my life, it is the best if you have no knowledge of code. It facilitates integration automatically, I definitely recommend it, it is very easy to use!

Update: We have resolved internal issues which resulted in the app not loading as expected. Most importantly though, the author has been in touch immediately to resolve this issue. Support is important! Original review: We are using this app to publish our GTIN data to Google Merchant Center and it worked without any issues. Today we were notified by Google that 90% of our products on GMC do not have a GTIN. So we try to check what is happening in GTM, but ... "cannot connect to server" ... is this app dead?

Don't even bother. Not only did they ask me to remove a template which was sort of working, they then didn't want to help to configure the tags in the template to ensure they are working. My Google Analytics is pretty much broken, not reporting any revenue or tag data and their customer service is shockingly terrible. I had initially used Niddocks who this company initially was, he was not only SUPER helpful, he was informative, technically sound and just plain great. The company then got sold to these guys and they have been cowboys ever since. After stressing that their tags were incorrect and infact their predecessor had added custom code to ensure the data layer objects could be ready, they then said I should pay $400 to get this fixed and they can take Paypal payments?! Seriously don't waste your time.

Rob helped me one-on-one and fixed every issue on my Shopify! He is so amazing, Best customer support I've seen before! This app is my highest recommendation for anyone - who is want to setup google tag manager!

Hands down best support I have received for an app this cheap - I would recommend 100% as the best solution to deal with all your shopify tracking needs.

Super helpful support went above and beyond just helping me install the app. They also helped with custom coding. This is the best solution for implementing Google Tag Manager on a Shopify store.

Its never been this easy to get all my tracking setup perfectly. Rob has been amazing, he responds within minutes at times and nothing is ever too difficult for him. Amazing service, highly recommended. Thanks Rob!

App does it's supposed to perfectly. But the support is incredible. Adwords can be a very confusing universe, but Niddocks is there to help you navigate it. This app is worth every penny.

This app has singlehandedly solved my biggest frustration with Shopify - the implementation of Google Tag Manager. The app works great, and the service is definitely there to back it up. They are genuinely very nice, helpful people. They set everything up for me, and even went back in after I installed a few tracking codes to make sure everything was working well. A for the product, A+ for support.

Finally, an app which means we can pull accurate source / medium through from ecommerce sales. This finally means we can track our sales and make sure we make the right marketing decisions. Great support too.
