Hi @Catchvikram444,
I wanted to take a moment and welcome you to our community. Thank you for your first contribution. I’m here to help you connect with experts in our community and get the answers you need.
You want to know how to implement GTM with GA4 in mind for your website and mobile apps but don’t know where to start. What your general approach should be. For that, our playbooks have your back: https://community.cxl.com/t/use-google-tag-manager/2381?u=tania. Our playbooks are built to guide you step-by-step and help you figure out what your starting focus should be.
Regarding your question of reusing the same tags, triggers and variables, we need to understand what that will help you accomplish. Is it to make GTM implementation easier? Or something else? Please let us know, because answering this will allow me to properly connect you with the right experts that can help you from our community.
Let me know what you think, and if you have more questions,
Tania
