Migration from Google Analytics to Google Tag Manager
I have a tough decision to make, and I would like a professional advice before to act.
I have always use GA to track the traffic and activities on our website (http://www.exlaluce.com.au/). Recently, I wanted to get more accurate information concerning the clicks and downloads on the website.
I found out that GTM was probably the best tool. Now that GTM is installed I keep watching tutorials saying that I should migrate from GA to GTM by removing the GA snippet from my code. The thing is that I am hesitating, I have already accomplished some work on GA and I wonder if I will have to set up GTM in order to get the same kind of information. Example: I have excluded the staff traffic and the spam & robots traffic from GA data. My data are now cleaned. If I migrate from GA to GTM, will I have to do this again in GTM?
I assume this might be a very easy question but I am not sure of the answer. I would really appreciate if someone could help on this one.
Thanks a lot,
