Tag PilotCut maintenance costs with a standard Google Tag Manager tracking stack
Tracking is a must-have for any online business, but with recent developments like server-side tracking it takes significant development and technical resources to build and maintain.
Learn how building on the Google Tag Manager ecosystem helps cut maintenance costs in the long run.
It’s hard to imagine a serious online business without tracking. It is important for understanding what drives sales and how users interact with your offer, and it is a requirement for any successful advertising campaign: without tracking, advertising platforms cannot scale the reach of your ads or tune their targeting.
At the same time, legal, technical and cultural changes around privacy and invasive tracking practices have made the tracking stack more complex:
- Consent Management Platforms,
- tag managers,
- server-side tagging,
- Conversions APIs,
- product catalogues and feeds.
As a result, choosing the right tracking solution is a strategic, long-term decision that can speed up or hold back business growth.
Here is why Google Tag Manager is one of the best long-term investments for your tracking stack.
An industry standard with an extensive ecosystem
Google Tag Manager launched in 2012. According to W3Techs, it has a 99.6% market share among tag managers (October 2026).
It is a mature, battle-tested system backed by one of the biggest tech companies. When a new tracking technology emerges, it quickly becomes available for Google Tag Manager.
Its popularity has also created a rich ecosystem: every part of the tracking lifecycle is covered by a wide variety of alternative, competing and complementary tools and services.
No vendor lock-in
Thanks to that ecosystem, there is little risk of vendor lock-in, where an ecommerce owner has too few options and is stuck with a single vendor to avoid a costly migration.
Your position as the business owner is protected by the modular architecture of Google Tag Manager based setups. The whole tracking setup is made of individual components:
- the dataLayer implementation (a tracking plugin),
- Consent Mode (a Consent Management Platform),
- Tag Manager templates and tags,
- server-side GTM hosting.
Each of these components can be replaced without major disruption to the whole tracking system, and they can come from different vendors.
Experts and customisation
The ecosystem is not just tools and products. It also means easy access to tracking specialists and to learning materials like step-by-step guides and videos.
Those experts and guides thrive because Google Tag Manager is not only the industry standard but also a very customisable solution.
What to watch out for
A modular, flexible tool like Google Tag Manager brings all the benefits above, but it also comes with risks.
Google’s documentation and standards are extensive, but they don’t cover every use case. Each vendor may implement the missing pieces differently, so switching between tools takes some low-level knowledge.
The same applies to freelancers and agencies: frequently changing implementation specialists can lead to accumulated technical debt, as each new expert may bring a slightly different approach, for example to naming conventions.
Our take
Make conscious decisions that benefit you in the long run: choose standard components you can replace, and keep one consistent approach across your setup, whoever implements it.
