We have a website with decent traffic and have been able to generate business from it. Currently, we have Google Analytics and Search Console and are getting data and these two are also linked. My CEO has been told by someone that we need to implement Tag Manager and move to the "next level".
I have no experience in doing this and I am very scared this can back fire and we can lose all data. Please can someone help?! If not anything, someone who can at least help with a "how to" guide or even some practical do's and don'ts?
