ISSUES WITH GOOGLE TAG MANAGER IN CHINA
Despite its advantages, Google Tag Manager faces significant issues in China mainly due to internet speed/loading difficulties and legal compliance concerns. GTM is a product of Google, which runs its services on its Cloud Infrastructure, Google Cloud Platform (GCP). Since Google services are intermittently blocked in China, it causes serious loading problems for websites using GTM.

Specifically, compatibility issues with Chinese websites make the loading process painstakingly slow. Websites that rely on GTM are unable to load efficiently, which affects user experience and website performance.
Furthermore, China has stringent laws regarding website compliance. Foreign businesses operating websites in the country must conform to these laws. However, since GTM is not based in China, websites using it often face regulatory hurdles and risk being blocked.

While GTM is an efficient tool for businesses operating outside China’s jurisdiction, within it, businesses might find it to be more of a liability than an asset due to the said issues.
