Google Tag Manager is your friend here. One code for Unbounce, containing all the scripts and tags you could want.

@vutuanminh are you naming your trackers? Would be helpful, if you can post your tracking script here.

hi @Malik, I add the GA tracking code using Script Manager

The first tracking code works but the second one doesn’t. Should I use Custom Script instead?

@Adam_Smartschan I haven’t used Google Tag Manager before so might need to learn it first. Thank you so much for your suggestion.

@vutuanminh you can’t add 2 tracking codes like that on Unbounce. You will have to add that as a separate global script. Not the default unbounce way… thats meant for when you have only 1 tracking code. Your default GA script has to be customized - like i said you have to name at least one tracker… see here

@malik thank you. I really appreciate your help.
