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?

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!

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.

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.
