Comparison · Shopify
Shopify’s Google app or your own Tag Manager? Standard cases: the app. Custom rules or two websites: your own Tag Manager.
Shopify’s app is the supported standard route. Your own Tag Manager through custom code gives more control and costs support and upkeep in return. This comparison separates the two cleanly, including what happens to the product feed.
The tracking check shows within two working days which route fits you. Credited if you commission within 30 days.
The two routes
- Shopify’s Google app: The supported standard route directly in Shopify
- Your own Tag Manager: Through custom code, full control over the reports
How we compare
-
Both routes can be right
After the check we pick the simplest route that meets your need, not the most expensive one.
-
No percentage promises
How much a route brings back depends on your visitors. Anyone promising a fixed number does not know your data.
-
The foundation first
No route repairs wrong numbers. If amount or reference are wrong in the shop, they arrive wrong everywhere.
-
Technical, not legal
Whether a setup is permissible is for you and your privacy advisers. We build the technology.
In short
The decision is not about the tool but about the need. If the standard reports and a supported route are enough, the app is the more stable choice. If the shop needs custom rules, a shared measurement with the main site or several websites, there is no way around your own Tag Manager. What matters: the app often delivers more than measurement, namely product feed and Merchant Center. Those connections are assessed separately.
In detail
The differences in detail
| Point | Shopify’s Google app | Your own Tag Manager |
|---|---|---|
| Setup | Through the Shopify channel, few steps, well described. | Custom code, build in Tag Manager and your own testing. |
| What gets reported | The standard reports in the shape the app provides. | Freely definable, with custom details and rules. |
| Control | Limited to the app’s settings. | Complete, with versions and a way back. |
| Product feed and Merchant Center | Delivered by the app. A reason of its own to keep it. | Not covered by this. The feed stays the job of the app or another solution. |
| Cookie banner | Bound to the app’s rules and to Shopify’s own consent. | Freely controllable, but yours to test. |
| Main site and shop | Not designed for it. Two websites stay two measurements. | Possible, together with the Tag Manager on the main site. |
| Support | Supported by Shopify. | Shopify explicitly describes custom code as an advanced, self-managed route with limited support. |
| Sealed-off environment | Not relevant for you. | The code runs sealed off. Page address, origin and test tools behave differently than usual. |
| Upkeep | Largely covered by the app. | Yours to follow up on when checkout, theme or platform change. |
| Ownership | The settings live inside the app. | Tag Manager and code sit in your account and can be taken along. |
The decision
What speaks for which route.
Your own Tag Manager pays off when
- main site and shop converge into one measurement
- custom reports or details are needed
- conversions should be created directly in the ad account
- several paths have to be aligned against double counting
- the settings have to be versioned and portable
- the limits of the sealed-off environment are accepted deliberately and tested
The app is enough when
- · the standard reports cover the need
- · only the shop is measured, without a second website
- · product feed and Merchant Center matter
- · nobody wants to maintain custom code
- · support matters more than custom rules
Both routes can be right. We sell neither custom code nor the app on principle. After the check we pick the simplest route that meets your need reliably.
Where it goes wrong
The most common mistakes
- App and Tag Manager run in parallel and report every purchase twice.
- The app is uninstalled although the product feed depends on it, and Merchant Center breaks.
- The custom code registers too late and misses early events.
- Google Analytics receives the placeholder address instead of the real page and attribution shifts.
- The code only loads when both consents are given and loses measurement data as a result.
- The order number is always the same, so the protection against double counting does not help.
Common questions
Does the Google app have to be removed?
Not automatically. Merchant Center, product feed, ad account and Google Analytics are assessed separately. Often the app stays for the feed while the measurement moves into Tag Manager.
Can Tag Manager run in Shopify at all?
Yes, through custom code. Shopify provides that route and calls it an advanced route with your own testing. The code runs in a sealed-off environment.
Why does the Google preview not work as usual?
The sealed-off environment can prevent the usual connection. We verify instead through the Shopify Pixel Helper, the network traffic and the reports in Google Analytics and Google Ads.
Can I switch later?
Yes. A switch runs in a controlled way: backup of the old state, parallel operation, verification, then switching off the old route. Without that sequence you get duplicate or missing purchases.
