Headless Shopify & GA4 tracking

[Charlieim]

Hi, 

We're currently working towards a Sanity (Next.js) & Shopify headless setup for a site. In theory, it'll all be served from the Sanity side and then when it comes to checkout, the user will be handed over to the Shopify side. The Shopify side will be hosted on a subdomain.

Just hoping for some advice about the best ways to track data / connect to GA4, please?

Hi,

Install and setup GA4 tracking in both Next.js and Shopify
Check cross-domain tracking set up

[Charlieim]

I had thought the same initially, however, after some research, it looks like there is the option of:

• Using GTM on the Next.js side 
• Using Google & YouTube app on the Shopify Side

Have the same Gtag/data stream for both platforms as GA4, by default, will track over subdomains and domains if the Gtag is detected on both. It's suggested that this doesn't require any set up of cross-domain tracking.

Does that sound right to you? Would you recommend another way instead?

[Small_Task_Help]

You can use GTM for both

[Charlieim]

That's great thanks for the help.

Would the Google & YT app be more accurate for data do you think?

Hello charlieim,

Google ads and YT app is accurate but not as accurate as Google Tag Manager. 

Google Tag Manager has the feature of server-side tracking with first-party domain setup.

server-side tracking with a subdomain or first-party domain bypasses all kinds of cookie blockers, IOS 14 updates or browser restrictions.
